CTS-Series Cooling Tower Filter Systems – Engineered for Cooling Towers, Closed-Loop Systems & HVAC Water Management

The Everfilt® CTS-Series Cooling Tower Filter is purpose-built for demanding environments like cooling tower basins, closed-loop systems, and HVAC water infrastructure, where the presence of organic and inorganic debris can compromise performance, reduce efficiency, and lead to premature equipment wear or failure. Designed for reliability and ease of integration, the CTS-Series offers powerful, scalable filtration solutions for both open and closed water systems.

Optimize Cooling System Longevity & Efficiency

Catch basin water contaminated with airborne dust, silt, or biological debris can clog nozzles, foul heat exchangers, and corrode system internals. The CTS-Series Cooling Tower Filter protects critical equipment by removing particulates down to 40 microns with standard filtration, or as fine as 5 microns using optional multi-media packs.

Versatile Configuration for Every System Type

Available in carbon steel, 304SS, or 316SS construction, the CTS-Series Cooling Tower Filter accommodates a wide range of system requirements, flow rates, and water chemistries. Whether used in open cooling towers, chilled water loops, or evaporative condensers, these freestanding, skid-mounted units come with optional starter motors, manual or automatic backwashing, and multi-mode control panels for seamless system integration.

Key Benefits
 

• Ideal for cooling towers, closed-loop HVAC systems, process chillers, and industrial cooling basins

• Filter options for 5, 10, 20, 30, or 40 micron removal, including multi-media filtration packs

• Constructed from carbon steel, 304SS, or 316SS to meet site-specific durability needs

• Removable 304SS wedge wire underdrains (no PVC or false bottoms) for long-term reliability

• Skid-mounted for ease of transport and rapid deployment

• Electric, pneumatic, or hydraulic actuated valve options

• Manual or automatic backwash modes to reduce maintenance demands

• Large side-access manways for safe, simple inspection and servicing

• NSF-approved 3M-134 interior coating with UV-resistant fuze-coated exterior for corrosion resistance
