Sub-Zero Refrigeration Dryers — Revolutionary Regenerative Refrigerated Dryers

Why choose a sub-zero refrigeration dryer?

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, delivering 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.

Optimised for Class 3 air quality

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 they apply to compressed air, or contact us for further information.

Features

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