Cyclone Filtration has emerged as a highly efficient method for keeping water clean in both closed-loop HVAC systems (heating and chilled water circuits) and open cooling tower circuits. In HVAC applications, water quality is just as critical as air quality – while an HVAC filter cleans the air, water circulating through chillers, boilers, and cooling towers also needs filtration to prevent fouling and corrosion. This blog explores why cooling tower filtration and closed-loop filtering are necessary, compares different technologies (bag filters, media filters, centrifugal separators, and cyclone filters), and highlights the unique advantages of cyclone separators. We also discuss Aevira’s advanced cyclone filtration solutions – detailing how they prevent water loss in closed systems, automate purging in open systems, boost sustainability by reducing water and chemical use, and integrate with Building Management Systems (BMS). Finally, we provide guidance on implementing a cooling tower water filtration strategy and a side stream filtration system for chilled water system applications, with a call to action to contact Aevira for expert assistance.
The Need for Filtration in HVAC Water Systems
Water is the lifeblood of HVAC heating and cooling circuits. In a cooling tower water treatment system, water continuously circulates to dissipate heat. Open cooling tower water
is exposed to the atmosphere, making it a magnet for dust, pollen, bacteria, and debris. Meanwhile, closed-loop systems (like chilled water loops and heating hot water loops) recirculate the same water, but they aren’t immune to contamination – internal corrosion, biofilms, and occasional ingression of makeup water can introduce particles. If these contaminants are not filtered out, they can wreak havoc on system efficiency and longevity. Sediment and sludge accumulation lead to:
Reduced heat transfer and poor temperature control: Deposits insulate heat exchangers, coils, and condenser tubes, impairing HVAC performance and causing heat transfer loss. For example, a layer of silt or rust in chiller tubes acts as an unwanted insulator, forcing chillers and boilers to work harder to reach set temperatures.
Corrosion and equipment damage: Particles can cause under-deposit corrosion on pipe walls and tube surfaces. In closed loops, steel pipes often shed iron oxide (magnetite) into the water; if not removed, this sludge circulates through pumps, control valves, and chillers, causing abrasive wear (e.g. pump seal leaks) and further corrosion. In open towers, abrasive sand or dust can damage pump impellers and valves if not caught by a cooling tower water filter.
Clogging and fouling: Without filtration, strainers, spray nozzles, and small passageways can plug up. Cooling tower spray nozzles and basin sweeper piping often clog with leaves or dirt, reducing cooling efficiency. In closed systems, blocked control valves or fouled coils lead to uneven flow and comfort complaints.
Biological growth and chemical inefficiency: Dirt in water provides a habitat for bacteria and algae. Nutrient-rich sediment can promote biofilms, including Legionella in cooling towers. Moreover, suspended solids can absorb treatment chemicals – for instance, corrosion inhibitors can adsorb onto silt and get filtered out or settle, and chlorine or biocides can be consumed reacting with organic debris. This means you’d need higher chemical doses to maintain effective levels if water is dirty. Clean water via filtration thus keeps chemical water treatment (like biocides and inhibitors) working optimally and reduces chemical use overall.
In short, whether it’s an open cooling tower filtration system or a closed-loop sidestream filter, filter cooling tower water and HVAC loop water is critical for maintaining efficiency, preventing damage, and controlling biological risk. Many building engineers now include sidestream filters as a standard part of both cooling tower water treatment packages and closed loop maintenance plans, rather than waiting for a problem to occur. “A side stream filter unit is a crucial part of a comprehensive water management system,” as Waterline’s journal notes – proactive installation extends equipment life and avoids costly downtime.
Closed Loops vs Open Cooling Towers: Different Challenges
Both closed and open systems benefit from filtration, but the nature of contaminants differs:
Closed Heating/Chilled Water Systems: These are “closed” to the environment, meaning water recirculates in sealed pipes and coils. However, closed loops still corrode internally over time, especially if water chemistry isn’t perfect. The most common contaminant is iron oxide rust (often a fine black magnetite sludge) from steel pipe corrosion. Even new systems can have installation debris (e.g. pipe scale, welding slag) or particulates introduced during maintenance. Without a side stream filtration system for chilled water system or hot water loops, these solids accumulate in low-flow areas like expansion tanks, coil headers, etc., causing gradual performance loss. The debris can also settle in heat exchangers, causing cold spots, or erode pump seals and valve seats. Closed loops typically rely on chemical corrosion inhibitors and biocides for water quality, but those alone can’t remove physical solids. Thus, a sidestream cyclone filter or magnetic trap is installed to continually pull a portion of the water, filter out particulates, and return clean water to the loop. Because closed systems don’t get continuous make-up water, preventing water loss during filtration is crucial – any water removed to take out sediment must be minimized or returned, to avoid introducing fresh oxygenated water that could accelerate corrosion. We’ll discuss how cyclone separators address this with zero-loss designs in the Aevira solution section.
Open Cooling Tower Circuits: These include the cooling tower sump, condenser water pumps, piping, and heat exchangers (chiller condensers or process coolers). Open systems are open to the air at the cooling tower, meaning they constantly ingest airborne dust, organic matter (like leaves, insects), and even microbiological spores. Additionally, as water evaporates in the tower, dissolved minerals concentrate, and some precipitate as scale or sediment. The open sump is essentially a settling basin where heavy particles can collect as sludge. If not filtered, this sludge will recirculate and foul equipment. Cooling towers commonly use cooling tower side stream filtration to combat this. By filtering a portion of flow continuously, the system removes suspended solids and prevents them from accumulating in the basin or heat exchangers. Cooling tower water filtration has been shown to improve heat transfer efficiency and reduce the frequency of manual cleanings. Unlike closed loops, open towers can afford (and in fact require) some water bleed-off (blowdown) to purge concentrated contaminants. Therefore, filtration systems for towers can periodically purge trapped solids to drain without adverse effect, as long as the water lost is compensated by fresh make-up water. This purge can even complement the tower’s regular blowdown by focusing on physical sediment removal.
How much flow to filter? In practice, a sidestream filter typically treats 5–15% of the circulating flow in the system. This is sufficient to turn over the entire system volume multiple times a day (e.g., filtering the full volume 2–3 times per 24 hours), which gradually polishes the water. Many engineers size a side stream filter for cooling tower circuits at about 10% of the tower recirculation rate. For example, a 76 l/s cooling tower loop might use a 7.6 l/s sidestream cyclone filtration skid. This continuous partial filtering has minimal impact on system flow but steadily removes contaminants. Because sidestream units operate in parallel, they do not interfere with the main flow – if a filter starts to clog, it won’t starve the chiller or tower of water, thus avoiding any risk to operations.
Now that we understand the need, let’s compare the filtration technologies available for HVAC water systems and see how cyclone filtration stands out.
Comparing Filtration Technologies for HVAC Water
Several filtration methods can be used in cooling tower filtration or closed-loop sidestream applications. The most common ones are bag filters, media filters (such as sand filters), screen/mesh filters, disc filters, and centrifugal separators (including cyclone filters). Each technology has pros and cons in terms of particle size removal, maintenance, water usage, and suitability. The table below compares bag filters vs media filters vs centrifugal vs cyclone filters for key factors:
Filtration Technology | Mechanism | Particle Size Removal | Maintenance & Consumables | Water Loss | Pros | Cons |
Bag Filters | Water is passed through a porous fabric bag that traps particles. Typically installed in a housing; bags can be made of felt, polypropylene, etc. | Fine filtration possible (selectable micron ratings, e.g. 1–100 microns). Effective for capturing even small particles until the bag fills. | Requires regular bag replacement or cleaning. Consumable cost for bags; labor to change. If solids load is high, bags clog quickly. Need to depressurize housing to service, causing slight water loss and downtime. | Minimal during operation (closed housing). Some water lost when opening housing to change bag, but overall low. | High efficiency (can remove very fine particles if proper micron bag is used). Simple housings with low initial cost. No continuous water waste during filtering. | High maintenance – frequent monitoring and bag changes. Not ideal for heavy dirt loads (bags foul rapidly). Replacing bags incurs ongoing cost and handling of waste. Interrupts flow during service unless duplexed. |
Sand/Media Filters | Beds of granular media (sand, multimedia) trap particles as water percolates through. Depth filtration mechanism – larger debris trapped at top, finer at lower layers in high-efficiency designs. | Standard sand filters: down to ~10 micronsenergy.gov (moderate fine). High-efficiency media filters (with fine sand or garnet layers) can remove down to ~0.5 microns energy.gov under ideal conditions. | Media beds eventually clog and must be backwashed to flush out captured solids. Backwashing (often automated) requires taking the filter offline or using a multi-cell design. Media may need replacement over years. No consumable cartridges, but pumps/valves for backwash add complexity. | Significant water usage for backwash. Each backwash cycle sends a volume of water to drain to carry away sediment. This is an expected part of operation – effectively a controlled water loss in exchange for cleaning the media. | Handles high dirt loads well – can filter large volumes of water and dirt capacity is relatively high before backwash is needed. Automated operation available (self-backwashing filters). Good for fine filtration needs (captures smaller particles than centrifugal units can in one pass). | Water waste from backwashing (can be 5% or more of throughput water used for cleaning, impacting water usage in cooling tower filtration system). Equipment is larger and requires ancillary piping for backwash waste and fresh rinse water. Also, captured organics in sand can promote bacteria if not backwashed promptly . Ongoing power cost for backwash pumps. |
Centrifugal Separators | Also known as hydrocyclones or swirl separators. Water enters a cone-shaped chamber tangentially at high velocity, spinning it. Centrifugal force flings heavier particles (sand, rust, etc.) to the perimeter; they settle into a collection chamber at the bottom, while cleaned water exits at the top. No physical filter media – separation is by inertia and gravity. | Medium coarser range. Efficient for heavier-than-water particles typically ≥ 40–75 microns (depending on design) . Removes grit, sand, rust flakes, and other dense solids very well. Will not catch finer silt (<20 µm) or low-density/fluffy debris in one pass. (Multiple passes in recirculation can gradually remove finer portions down to ~20 µm over time.) | Minimal maintenance. No cartridges or media to replace. The only regular task is purging the collected sediment from the bottom chamber. Can be manual (opening a valve periodically) or automated via an electric purge valve and timer. No consumable costs. Wear parts are minimal (no moving parts; maybe occasional gasket/seal replacement). | If purged to drain, each purge loses a small amount of water along with the sediment. However, purge intervals can be optimized to reduce water loss to nearly zero (especially if using a recovery vessel – see Aevira’s solution). Generally, very little water is wasted compared to sand filter backwash. Some advanced systems capture the purge in a bag or tank to avoid any water loss. | Simple & reliable: no moving parts to foul, long service life. Virtually maintenance-free: no filter cleaning needed, just sediment purge. No filter replacements means lower operating cost. No backwash needed: hence very low water waste and no disruption of flow. Low, steady pressure drop: typically ~5–12 psi loss that stays constant (doesn’t increase over time as in media filters that clog). Great for continuous operation and handling large volumes of sediment over time. Compact footprint for the flow rates handled. | Limited fine filtration – will not remove very fine particles, colloids, or lighter-than-water matter (like floating organic bits) effectively. May need to be paired with a polishing filter (e.g. bag or cartridge) if ultra-fine filtration is required. Performance is tied to maintaining sufficient flow velocity; if flow falls outside design range, separation efficiency drops. Typically requires a steady flow pump for best results. Not effective for oil/grease (which are lighter than water) – those require different separators. |
Cyclone Filters (Advanced Hydrocyclones) | Cyclone filtration refers to refined centrifugal separator designs often integrated into side stream filtration systems. Aevira’s cyclone separators, for example, use the same vortex principle but add enhancements like an enlarged sediment collection vessel or secondary filter stage. They spin out heavy solids and either automatically purge them or store them for later removal. | Similar size range to standard centrifugal separators for primary separation (capturing large suspended solids like sand, grit, rust >40 µm efficiently). However, unique designs can improve fine capture: e.g. an internal trap or screen might catch finer particles that the vortex alone doesn’t remove. In practice, cyclone filters excel at bulk solid removal and can reduce overall particle loads by >90% for common cooling tower debris. They ensure that only a much smaller fraction of ultra-fine particles remain for perhaps chemical treatment or secondary filters to handle. | Very low maintenance by design. No regular replacements needed since there’s no filter media – only periodic purging or cleaning of the collection vessel. Aevira’s systems incorporate bag filter housings for closed loops, meaning the separated solids are captured in an easily removable bag without venting water (the closed system stays pressurized). In open systems, automated purges can flush the sediment to a drain or trap. Maintenance mostly involves checking that purge valves and sensors (if any) operate correctly, and emptying any collection bag at scheduled intervals. | Zero or minimal water loss. Cyclone filter systems can be configured to avoid water loss entirely in closed systems (capturing sediment in a bag or chamber). In open systems, purged water is part of normal blowdown and kept to a minimal amount. Compared to sand filters that send hundreds of gallons to waste during backwash, cyclone systems might only lose a few gallons per purge cycle – or none at all if using a closed capture. | Robust and sustainable: Cyclone filters have no consumables and no moving parts, ensuring long-term durability and steady performance. They prevent water waste – especially in closed loops where water makeup is undesirable, cyclone units with collection achieve near zero water loss lakos.com. They are easy to install (often skid-mounted) and integrate into existing systems with a simple parallel connection. Cyclone filters also maintain water quality without chemicals – by removing solids, they reduce the need for flocculants or dispersants, and help chemical treatments (like biocides/corrosion inhibitors) work more effectively, thereby potentially reducing chemical dosing needs. Overall, they offer a set-and-forget solution for cooling tower water filtration and HVAC loop protection. | Specific to heavy solids – like all hydrocyclones, they primarily target dense particulates. Extremely fine or low-density suspended matter might still require supplemental treatment (filtration or settling). Thus, while cyclone filters handle the majority of typical HVAC debris, in polishing applications (like ultrapure systems) an additional fine filter or cartridge might be added downstream. Initial cost can be higher than a basic strainer or bag filter unit, but the life-cycle cost is low due to minimal maintenance (often paying off in saved water, labor, and consumables within a few years). |

As shown above, cyclone filtration offers an excellent balance for HVAC water treatment: it removes the troublesome particles that cause 90% of the issues (the heavy silt, sand, rust) with virtually no ongoing cost or water waste, which is a huge advantage in facilities focused on sustainability. Next, we’ll zero in on the unique selling points of cyclone filters and why they are often the preferred cooling tower filtration choice for engineers and facility managers looking for reliability and efficiency.
Unique Advantages of Cyclone Filters (USP)
Cyclone separators (sometimes called hydrocyclone sand separators) have several unique selling points compared to other filtration methods:
No Consumable Filters: Unlike bag or cartridge filters that must be replaced regularly, a cyclone filter has no disposable media. It continuously separates out solids without needing filter cartridges, which means lower operational cost and less waste. This not only saves money on consumables but also reduces environmental waste (no used filter bags to landfill).
Minimal Maintenance and Downtime: Cyclone units have no moving parts and don’t get “clogged” in the traditional sense. The pressure drop remains steady and low as solids collect in the separator’s sediment chamber. Maintenance is usually limited to periodically purging the collected sediment. This purge can be automated (e.g., a motorized valve opens for a few seconds on a timer or when a sensor detects a full collection chamber). There’s no need to shut down the system for cleaning – filtration occurs without interrupting operation
. Plant personnel spend far less time on filter upkeep compared to backwashing a sand filter or swapping bags.
Very Low Water Loss: Cyclone filtration is a water-sustainable solution. Media filters can waste hundreds or thousands of liters in frequent backwashing, and even simple bleed-off of dirty water from a cooling tower wastes treated water. Cyclone filters, by contrast, isolate sediment with little to no water. In closed loops, separated solids can be held in a chamber or bag filter housing and removed without dumping any water from the system (a key Aevira design feature). In cooling tower systems, any purge is short and targeted, significantly reducing the volume of water blown down solely for cleaning purposes. Some cyclone systems boast “zero water loss” during normal operation– a big plus for water conservation goals.
Energy Efficiency and Protection of Equipment: By keeping water free of sediment, cyclone filters ensure heat exchangers and cooling surfaces stay clean, which maintains high energy efficiency. Even a thin layer of scale or sludge can greatly reduce heat transfer; by preventing that layer, cyclone filtration helps HVAC systems run at optimal efficiency. Clean water also protects pumps (reducing wear from abrasive grit) and prevents blockages in strainers and coils, thereby avoiding pressure drops that would make pumps work harder. All these effects mean energy savings and prolonged equipment life.
Enhanced Water Treatment Efficacy (Chemical Reduction): Cyclone filtration improves overall water quality, which means any chemical treatment regimen can be more targeted and potentially reduced. For example, if solids are effectively removed, you may be able to eliminate certain dispersant chemicals that were previously used to control sediment or turbidity. Biocides work better in water free of sludge (since biofilms have less substrate to grow on), possibly allowing lower biocide dosage to achieve the same bacterial control. Also, with cleaner water, systems can run at higher cycles of concentration (in cooling towers) without fouling, which saves water and chemical usage on makeup. In some cases, facilities have reported 20–30% reductions in chemical use and notable water savings after implementing high-efficiency side-stream filters.
Compact and Easy Retrofit: Cyclone filter systems are typically skid-mounted and compact relative to their flow capacity. They can be easily added to existing mechanical rooms or cooling tower piping with minimal modification – usually just a matter of piping a sidestream pump discharge into the cyclone unit and returning the clean flow to the sump or system. Their small footprint and simple tie-ins make them ideal for retrofits in crowded plant rooms where a large sand filter vessel might not fit.
Reliability in Harsh Conditions: Because of their simple construction, cyclone separators can handle a wide range of water qualities (high temperature closed-loop water, dirty cooling tower water, etc.) without issues. There’s no filter media to degrade in hot water or foul irreversibly. Facilities that experience periodic “upset” conditions (like an influx of dust during a construction project, or corrosion after a system is opened for repair) especially benefit – a cyclone will simply collect the extra debris and can be purged as needed, whereas other filters might choke up and require emergency servicing.
In summary, the USP of cyclone filtration is hands-off protection of your HVAC water systems: once installed, it quietly and continuously defends against the sludge and grit that would otherwise impair your system. This brings us to how Aevira leverages these advantages in their cyclone filtration solutions.
Aevira’s Cyclone Filtration Solutions for HVAC & Cooling Towers
Aevira has developed specialized cyclone filtration systems tailored to both closed-loop HVAC applications and open cooling tower water treatment. Our designs maximize the inherent strengths of cyclone separation while addressing the specific needs of each system type. Here’s what sets Aevira’s cyclone filtration solutions apart:
Zero Water Loss in Closed Systems – Bag Filter Integration: In closed heating or chilled water loops, maintaining system volume is critical. Aevira’s cyclone units for closed loops come with bag filter housings integrated on the separator’s discharge. As the cyclone spins out particles, those solids collect in a bag inside a sealed housing instead of being sent to a drain. This means you can periodically remove the accumulated sediment by just replacing or cleaning the bag without draining any water from the system. The closed-loop pressure and volume are preserved. This approach marries the best of both worlds – the cyclone does the continuous heavy lifting (separating out most solids), and the bag provides a convenient capture method for fine sediment, all while preventing water loss and avoiding introducing oxygen. It also makes it easy to inspect what’s been captured – operators can pull out the bag during scheduled maintenance to see the volume and type of debris being removed (often an eye-opener for those who assumed their “closed” system was clean!). By using bag filter housing as a collection vessel, Aevira ensures closed-loop filtration can run indefinitely with no need for make-up water or system shutdown to purge. This is a key differentiator for facilities aiming to maintain sealed systems with minimal top-up.
Automatic Purge for Open Cooling Towers: In open cooling tower circuits, Aevira’s cyclone filter systems include an automatic purge function to periodically expel collected solids. The separator’s bottom collection chamber is fitted with a motorized purge valve (and optional controller or timer). At set intervals – or based on differential pressure build-up or volume sensors – the valve opens for a short duration, flushing concentrated sludge out to a waste line. This automated purge keeps the separator’s storage section from overfilling and ensures removal of sediment from the system entirely. The purged water, which carries all the dirt, can be sent to the facility’s drain or even a recovery tank if desired. Because cooling towers regularly require blowdown to control water quality, the purge can be timed to coincide with that process, making it effectively part of the cooling tower water treatment system operation. The purge frequency and duration are adjustable based on how dirty the water is – heavy dirt environments might purge daily; cleaner environments, maybe weekly. In any case, it’s a set-and-forget cleaning cycle – operators do not need to manually intervene. Importantly, the purge waste is much smaller than a typical sand filter backwash; only the sludge concentrated by the cyclone is removed, which is a fraction of the total flow (thus saving water). By automatically expelling sediment, the system prevents re-entrainment of settled solids and keeps the cooling loop extremely clean (often the tower basin will be visibly cleaner, with clear water that allows you to see the bottom of the sump).
Sustainability Benefits – Water and Chemical Savings: Aevira’s cyclone filtration aligns with green building goals and sustainable operation. First, as noted, water savings are substantial. Reducing routine water wastage is beneficial for both the environment and the utility bills. Facilities that switch from older filtration methods to Aevira’s cyclone system have seen lower makeup water consumption since we’ve eliminated continuous backwashing or excessive bleed. Second, chemical reduction is achieved by virtue of cleaner water. With less suspended solids, your biocides, corrosion inhibitors, and anti-scalants perform more effectively, often enabling a cutback in dosage rates over time. Moreover, by physically removing organics and nutrients, the filter lessens the biological load, potentially reducing the reliance on aggressive biocides.
Some clients even explore running their cooling towers with minimal chemical treatment, using Aevira’s filters plus secondary devices (like UV) to maintain water quality – in such scenarios, the cyclone filter is crucial to remove the food source for microbes and the silt that shields bacteria from UV or biocides. Additionally, Aevira’s systems don’t require any chemicals for their own operation (e.g., no flocculants or filter aids), unlike some traditional water clarifiers. All these factors contribute to a more eco-friendly water management approach. Finally, keeping equipment clean extends its life and efficiency, indirectly saving the energy (and carbon footprint) associated with manufacturing replacements or consuming extra power due to fouling.
BMS Interfacing and Smart Control: All of Aevira’s cyclone filtration packages are designed with modern building integration in mind. They come with instrumentation and control options that allow seamless BMS (Building Management System) interfacing. For example, differential pressure sensors across the cyclone unit can monitor if abnormal pressure drop occurs (which could indicate unusual blockage or a closed valve), and send an alarm to the BMS. The purge control unit can be tied into the BMS such that purge events are logged and can be triggered remotely if needed. Flow sensors or hour meters can track how long the unit has been running, and this data can feed into maintenance schedules. Aevira can also outfit the system with water quality sensors (turbidity, ORP, etc.) as part of a holistic water treatment monitoring system, all visible on the central BMS. The benefit of BMS connectivity is remote telemetry and control – facility managers can verify the filtration system’s status at a glance (e.g., “purge valve open” indicator, or an alert if a collection bag is full in a closed system via a level switch). This reduces the need for manual inspections and ensures that the filter is always functioning as intended. In critical facilities like data centre's or hospitals, this integration provides peace of mind that the side stream filter for the cooling tower or chilled water loop is protecting the system continuously, and if any issue arises, it will be immediately known and can even trigger backup actions.
Custom Sizing and Skid-Mounted Solutions: Aevira offers cyclone filtration units in a range of sizes to fit various system flow rates and contamination levels. Whether it’s a small 100 L/min secondary circuit or a large 2000 m³/hr industrial cooling tower, we can size the cyclone separator (or multiple separators in parallel) to handle the job. Our engineering team considers factors like particle types (e.g., sand, iron oxides), particle size distribution, specific gravity, system temperature, and flow characteristics when selecting the model – ensuring optimal separation efficiency. Systems can be skid-mounted with integrated pumps (if a side-stream pump is needed), valves, controls, and even pre-filtration (like a strainer guard for very large debris) so that the unit arrives as a plug-and-play package. This greatly simplifies installation for the contractor – just connect the inlet/outlet and power up the controls. Aevira can also design side stream filtration system for chilled water systems that incorporate magnetic separators in tandem with cyclones to catch both non-magnetic and magnetic particles, giving a comprehensive solution for closed loop cleaning (magnetite is magnetic, so a combo of magnet + cyclone is extremely effective in closed chilled water loops). Our cooling tower filtration skids can include basin sweeping pumps as well, which push sediments toward the cyclone intake, ensuring no dead zones in the cooling tower basin. These tailored solutions underscore Aevira’s commitment to providing not just equipment, but a complete filtration strategy that addresses the unique challenges of your facility.
In essence, Aevira’s cyclone filtration systems embody efficient engineering and sustainable operation – they keep your water circuits crystal clear with minimal oversight, ensuring your chillers, boilers, and cooling towers run at peak performance year-round.
