Refrigeration Dryer Series - PRD10-PRD250 (10-250 SCFM)

Refrigeration air dryers are ideal for general purpose oil free air treatment applications. Dewpoints of 38°F to 50°F are suitable for many indoor applications where general removal of water and some vapor is suitable for the end user's process.

Description
    PRD Series refrigeration air dryers are ideal for general purpose oil free pneumatic air treatment applications. They typically provide pressure dew points of 35°F (1.7°C) to 50°F (10°C) pressure dew point (pdp).  Refrigeration air dryers work by cooling the air, so are limited to positive pressure dew point ratings to prevent freezing of the condensed liquid. Refrigeration dryers use a set of heat exchangers or a single heat exchanger (with chambers) first to pre-cool the air; second to refrigerate the air to condense out moisture vapor; and last to re-heat the air to prevent pipe sweating downstream particularly in humid conditions.

    Non-Cycling (Direct Expansion) dryers are a type of dryer where the compressed air and the refrigerant come into direct contact via the heat exchanger. While reliable and simple to use, they generally require that the unit continues to run regardless of actual compressed air flow through the dryer. Cycling dryers that utilize a thermal mass as the means to absorb the heat from the compressed air. By chilling a thermal mass, a refrigerant compressor may turn off in times of low demand thereby saving energy by shutting off the refrigerant compressor.
