FAQ: Frequently Asked Questions For Everfilt Cooling Tower Filters

Why Choose an Everfilt® Cooling Tower Filter System?

Cooling tower filter systems are key components to maintaining a clean and effective cooling tower. Dirt, algae, dust, and other airborne debris most commonly hinder the performance of the cooling tower itself. Keeping the circulating water clean and free of debris provides a more efficient cooling system while avoiding the risk of potential downtime and costly repairs. Closed-loop filtration systems are great solutions and require minimal connections when implementing into a new or existing cooling system.

The Everfilt® CTS-Series stands apart from competing cooling tower filters through its durable welded stainless steel wedge wire underdrain system, which provides superior flow distribution, improved filtration performance, more effective backwashing, and longer equipment life. Additionally, its highly customizable design and maintenance-friendly features, including skid-mounted turnkey options, removable underdrains, large access manways, and automatic backwashing, allow for easier integration, reduced installation and operating costs, and simplified long-term maintenance.

1. What Filtration Levels are Available with the CTS-Series Cooling Tower Filters? 

The CTS-Series can provide filtration down to:

• 40 microns with standard filtration

• 30, 20, 10, or 5 microns with optional multi-media filtration packs

The appropriate filtration level depends on water quality requirements and system sensitivity.

2. What Types of Cooling Systems Can the CTS-Series Cooling Tower Filters Be Used In? 

The CTS-Series is commonly used on:

• Cooling towers

• Closed-loop HVAC systems

• Chilled water systems

• Process cooling systems

• Evaporative condensers

• Industrial cooling basins

• Data center cooling systems

• Manufacturing facilities

3. How Does the CTS-Series Protect Heat Exchangers & Chillers? 

The CTS-Series removes suspended solids before they reach critical equipment.

Cleaner water helps prevent:

• Heat exchanger fouling

• Chiller tube blockage

• Pump wear

• Valve damage

• Reduced thermal efficiency

Maintaining cleaner water often leads to lower energy consumption and reduced maintenance requirements.

4. Is the CTS-Series Available with Automatic Backwashing? 

Yes, the CTS-Series is available with:

• Manual operation

• Automatic backwash operation

• Pneumatic controls

• Hydraulic controls

Automatic backwash systems help reduce labor requirements and keep filtration performance consistent.

5. What Flow Rates Can the CTS-Series Cooling Tower Filters Handle? 

The CTS-Series is available in a wide range of configurations capable of handling:

• Flows from approximately 25 GPM

• Systems exceeding 3,000 GPM

Single-vessel and multi-vessel designs are available for larger applications.

6. Are There Available Color Options? 

Yes, as long as they are chosen from our color chart, over 100 options are available.
