The revolutionary CMT dryer is the only regenerative refrigerant dryer available in the compressed air market today. It combines the sub zero pressure dew point (PDP) of a typical regenerative desiccant dryer, with the low operating and energy costs of a refrigerant dryer, to provide an extremely low total cost of ownership (TCO). Sub zero air dryers take clean, dry air to new levels of cost-efficiency across a broad spectrum of operating conditions.
Many applications require very dry, high-quality air with sub zero dew points. CompAir’s desiccant dryers are the best option for the most stringent requirements – ISO Class 1-2 with a pressure dew point (PDP) as low as -70°C (-94°F). However, ISO Class 3 air, with a PDP of -20°C (-4°F), is sufficient for a large portion of the market. For applications that only require Class 3 air, we've expanded our family of high quality air dryers with our CMT dryers. They combine the ease of maintenance and operation of a refrigerated dryer with the sub zero pressure dew points typically associated with a desiccant dryer. Please download our white paper at the bottom of the dryers homepage to learn more about the ISO classes and how the apply to compressed air.

Air enters the dryer through the pre-cooler/re-heater
Leaving the pre-cooler/ re-heater, the air enters the first heat exchanger for regeneration
With only 15% of the of the moisture remaining, the air now enters the sub zero dryer heat exchanger where it is cooled and dried to -20°C (-4°F) PDP.
The air dried to -20°C (-4°F) PDP is reheated before exiting the dryer in two steps.
