The Free Cooling Units system module takes over the control of the existing comfort A/C units and adds economical direct free cooling to the energy-intensive compressor cooling function. Whenever the ambient temperature allows, Free-Air is activated and the comfort A/C units are switched off. Free-Air has been thoroughly tested, is simple to install, ready for operation immediately and easy to maintain.
Free Cooling is the key to unlock substantial energy savings in telecom shelters and rooms. Our free cooling units provide our customers with huge energy savings around the clock and have done so for years.
Free Cooling controlled ventilation it removes excessheatfromtelecombasestationsand cools down the shelter or enclosure by use of ambient air. No compressor is involved in free cooling. The free cooling system is significantly more economical in use than air conditioners. One will typically save 70-95% of your energy for cooling by switching to ACME's free cooling units.
