REFRIGERATED DRYERS RDX-series

For complete drying of compressed air, it is necessary to use refrigerated dryers. RDX series Constant low dew point for efficient
dehumidifiers are a robust design with low pressure loss and high efficiency. moisture removal even in the case of
variable compressed air flow conditions

RDX-series refrigerated dryers with a capacity of 0.4–36.0 m3/min are equipped with an efficient cast-aluminium
heat exchanger and an inbuilt coalescence separator. The low degree of pressure loss due to the inbuilt separator
and the reliable outer insulation of the heat exchanger facilitate a high level of energy efficiency for the system. The
coalescence separator is insensitive to pressure fluctuations in the case of varying load and reliably removes up to 98%
of condensed moisture.

Combined 3-in-1 heat exchanger

The combined heat exchanger in an RDX refrigerated dryer
consists of three functional units: an air/air heat exchanger, an
air/refrigerant heat exchanger and a coalescence separator.
The air/air heat exchanger pre-cools hot compressed air.
This saves up to 50% in energy in the subsequent refrigerant
cooling process. At the same time, cold dry air leaving the
dryer is heated to a suitable temperature for subsequent use.
The air/refrigerant heat exchanger brings the temperature of
the compressed air to dew point. The coalescence separator
removes condensate from the compressed air. The separated
condensate is periodically discharged by the condensate drain
valve.
