Why Choose Refrigeration Dryers?

Compressed air is an important provider of energy for industry; what is often overlooked however is the need to provide quality treatment for this air. Compressed air contains condensate which, when cooled, will turn into water, causing extensive damage to both the compressed air network and the finished product itself.

DRD refrigeration dryers actively remove this condensate to achieve near perfectly dry compressed air. The benefits are notable: less system downtime, reduced costs and maintenance, and an improved finished product. DRD, thanks to its PlusPack heat exchanger (patent pending) and the most compact dimensions on the market, will prove a major asset in your factory.
