At higher ratings in particular, heat-regenerative adsorption dryers are more efficient and most notably more cost effective to run than cold-regenerative ones.Key data: Pressure dew point: -40°C at 100% nominal load Volume flows: 245 - 4280 m3/h Operating pressure: 4 - 16 bar (overpressure) Ambient temperature: 5 - 50°CAdvantages: Ideal positioning of heating elements in drying bed Optimum use of regenerative energy Low maintenance costs Simple installation/operation Constant pressure dew point
