Free Coolers

Aqua-Vent™ free coolers automatically offload refrigeration compressors in cool weather

Operating Range

High Temperature

85° F

Low Temperature

-20° F

The Basics

Uses cool ambient air to directly cool your process fluid allowing compressors to be turned off and saving energy
Maintenance free automatic system switches chiller on and off according to ambient temperature
Lower yearly chiller running hours guarantees long system life span

Optional Features

Fully customizable system that can be made to fit any application or cooling requirements
Integrated free cooler on air cooled chillier


These integrated cooling/chilling systems are the perfect compromise between the high-energy efficiency of air-cooled heat exchangers and consistent temperature control of industrial chillers. 

During cool weather the “free-cooler” or watersize economizer is capable of handling the entire cooling load. During warm weather, when the “free-coolers” cannot cool as efficiently they cannot keep up with the cooling requirements so the system automatically switches the chiller system on to provide supplemental cooling. 

This system provides a number of benefits:

The primary benefit is the energy savings.  Turning off the compressor saves a huge amount of energy.  Typically, running a “free-cooler” can reduce your energy consumption by more than 75%.  This is substantial, especially in northern climates where you can turn off your chiller for several months during the year.

 Second this fully integrated system provides an alternative to high maintenance evaporative cooling towers that require cleaning and draining in environments where freezing is an issue. This system is completely automatic with no input or maintenance necessary between seasons and even more important, no maintenance will be necessary during the winter

Third this system guarantees a long operating life because most of the year the load is taken off the chiller and specifically the compressor. This significantly reduces the compressors yearly running hours and provides a longer system life span.
