Smart cooling increases the efficiency of air conditioning and refrigeration

by 20-70%.


Save Money

Why continue to waste an average of 30% of the money you are spending on HVAC/R energy costs? Even on the newest systems, COOLNOMIX® delivers a rapid payback.


Boost Performance

No one likes temperature swings. With dual sensors, COOLNOMIX® provides your system with more accurate temperature control, offering employees a more comfortable work environment.


Cut Emissions

COOLNOMIX® reduces energy waste by optimizing compressor operation so that your system only runs when it needs to. This efficiency lowers power plant greenhouse gas emissions and criteria pollutants.


No Maintenance

COOLNOMIX® is an add-on retrofit device which does not require infrastructure changes. Just set up and save.

COOLNOMIX® has helped organizations worldwide eliminate unnecessary fluctuations and wasted energy.

How It Works

COOLNOMIX® (CNX) is an add-on technology for commercial direct expansion (DX) cooling systems that helps the existing control system improve the temperature stability and energy efficiency of the vapor-compression refrigeration cycle, resulting in a reduction of 20-70% of its energy consumption.



A Low-Cost Retrofit Option
The device is placed in the cooling system circuitry in series between the existing thermostat and the control unit. It’s non-invasive and therefore won’t affect your warranty.

Adaptive to Variable Demand
Utilizing two hard-wired precision sensors and a relay-based controller, artificial intelligence will help the control system determine the optimal time to call for cooling, and then run the compressor at this time.


Key Features

  • Set and Save: No maintenance required.

  • Quality Ensured: 3 Year Manufacturer’s Warranty.

  • Resilient: Standalone device requires no integration or connectivity to function.

  • Dual Sensors : Provide indoor comfort quantification and more precise cooling delivery.

  • Energy consumption optimization : Compressor runtime is reduced once required comfort levels have been achieved.

  • Compressor health protection: Ensures a minimum cooling system run-time of 3 minutes and a minimum off-time of 3 minutes.

  • Bluetooth Monitoring: The COOLNOMIX® Connect app provides powerful insights at your fingertips.



COOLNOMIX® for Air Conditioning

Once you add COOLNOMIX® to your existing HVAC system, it’ll keep the temperature right where it needs to be. No unnecessary fluctuations. No wasted energy. Improved indoor comfort.

    • Air Conditioning Setpoints : 61-88 °F


  • Compatible DX Units : Packaged Rooftops, Splits, VRFs

A Smart Investment

Nippon Comsys Corp, Japan’s largest telecom engineering contractor, piloted 15 COOLNOMIX units on some of the newest VRF cooling systems. Due to the overwhelming success of the pilot, which averaged 40% savings, Comsys equipped all Mitsubishi units in their headquarters with COOLNOMIX. As the design authority of NTT, Comsys has recommended that NTT Docomo roll out 40,000 units at 20,000 mobile phone base stations, estimating that NTT would save $500 million over 10 years.
