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.

Adjusting dryer's capacity for different operating conditions
For complete drying of compressed air, it is necessary to use refrigerated dryers. RDX series dehumidifiers are a robust design with low pressure loss and high efficiency.
The capacity applies to a working pressure of 7 bar, a compressed air temperature at the dryer's inlet of 35°C and an ambient temperature of 25°C, according to DIN ISO 7183. In order to calculate the dryer's capacity for real operating conditions at the dryer's inlet, please use the following correction coefficients:
Capacity(air compressor) x F1 x F2 x F3 = Capacity(dryer).
Example:
For an air compressor capacity of 1.6 m3/min, a working pressure of 4 bar, a compressed air temperature at the dryer's inlet of 45°C and an ambient temperature of 35°C, the required capacity of the refrigerated dryer is calculated as follows:
Capacity (dryer) = 1.6 x 1.25 x 1.39 x 1.14 = 3.169 m3/min.
