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.
