Self-Cleaning Water Filters for HVAC Applications

Industrial heating, ventilation, and air conditioning (HVAC) systems depend on clean cooling water to function efficiently. However, this water is often contaminated by airborne dust, sand, pollen, algae, and pipe scales. These contaminants circulate through heat exchangers, chillers, and compressors, significantly reducing cooling and heat transfer efficiency and increasing maintenance costs. Dirt particles settle on warm surfaces, causing fouling and scale buildup, which impacts performance and shortens equipment life. Proper water filtration is key to addressing these challenges. Tekleen Automatic Self-Cleaning Filters ensure your HVAC system runs at peak efficiency while protecting critical downstream equipment.

The Problem: Contaminated Cooling Tower Water

Cooling tower water contamination causes:

  • Reduced cooling efficiency: Dirt and debris block heat transfer and foul surfaces.
  • Increased maintenance needs: Fouling and scale buildup demand frequent cleaning and repairs.
  • Higher operational costs: Scale formation increases water pressure drops and energy consumption.

A study by Carrier® found that just 0.002 inches of fouling increases pumping needs by 20%.

The role of water filtration in HVAC systems and key challenges

Effective water filtration ensures that HVAC systems operate at peak efficiency. It prevents scale buildup in heat exchangers, a critical factor for maintaining heat transfer efficiency. Filtration protects downstream equipment from particulate damage, safeguarding expensive components and prolonging their lifespan, and minimizes biological fouling – reducing the risk of system inefficiencies caused by bacterial or algal growth. These benefits collectively result in lower maintenance costs and reduced system downtime, enabling HVAC systems to function reliably.
