The beauty of the device is in the simplicity. The CoolPro is just an adaptive algorithm that shaves time off the end of the compressor run cycle and gets its cues from the call for cooling. If the call for cooling is satisfied, then the CoolPro shaves off more time. If it isn’t, it shaves off less time and adapts. It is really just a simple control beyond the system on/off switches utilized by A/C and Commercial refrigeration. The result is 25-30% less compressor run time/energy savings. It does not affect comfort or normal compressor operation or cycling. The CoolPro is brought to you by V-Blox, a 15 year old OEM without a negative comment and over 8,000 commercial and industrial customers.
