The Atlas Copco FD 40 Refrigerated Air Dryer uses a refrigerant circuit and heat exchanger to pre-cool air, refrigerate it to condense out moisture vapor, and then re-heat the air to prevent pipe sweating downstream. The compact brazed plate or aluminum heat exchanger was designed specifically to provide optimal pre-cooling and the lowest possible pressure drop. The electronic no-loss condensate drain comes with a level sensor to open the drain only when needed, preventing unnecessary loss of compressed air.

An Elektronikon Alpha controller displays the pressure dew point and relative humidity. The unit includes a remote alarm and start/stop control through voltage-free contact. FD dryers use CFC-free refrigerants (R134A and R410A) with an ozone depletion potential (ODP) of zero. Capillary tubes cope with all conditions, with no moving parts. A condenser with louvered fin technology improves performance in dusty environments.
