In a heat-regenerated system, heated ambient air is used for regeneration. In this system no purge air is lost, so the amount of air "in" is equal to the amount of air "out". A Delair® DB dryer would be applicable where a low pressure dew point of –40°C is required. Our Delair™ DB-LD is capable of reaching a dew point of –70°C. In very critical manufacturing processes, such as found in the semi-conductor industry, the DB-LD dryer is much appreciated, due to its excellent air quality and low running costs.
