Many smaller compressors do not use an aftercooler in their designs. Therefore compressed air exits the compressor at about 100 oC temperature. Dalgakıran high temperature dryers incorporate an aftercooler to reduce the inlet temperature, providing efficient dewpoint management.
HIGH TEMPERATURE DRYER—DRD H SERIES
- High operating inlet temprature
- Integrated condenser
- Independent air cooled aftercooler
- Moisture separator
- Auto drain
- Easy installation and maintenance
THE REFRIGERANT CIRCUT AND INSULATION
Dalgakıran exclusivesly uses environmentally friendly R134a refrigerant gas in the dryers. This refrigerant is suitable for both high temperature applications. R-134a has excellent thermodynamic properties and can operate at very low pressure compared to other refrigerants.
This will in turn increase the refrigerant compressor’s service life. With R-134a Dalgakıran dryers can operate at very high ambient temperatures. Dalgakıran engineers add extra capability to the heat exchangers with a superior no loss insulation system.
Dalgakıran DRD H Series Digital Cycling air dryers supply constant dewpoint at all flow ranges. This perfect insulation philosophy continues to the refrigeration circuit side also. Superior insulation and oversized condensers (for ultra-high ambient temperatures) enable the DRD H Series Dryers to offer continuous air quality.
