ELGi Airmate EGRD 200 and EGRD 500 series air dryers

ELGi Equipments recently expanded its range of high-efficiency non-cyclic refrigerated air dryers with the inclusion of three-phase options on five of its medium-sized models that produce flow rates from 210 to 590 cfm (5.95 to 16.71 m³/min).

The Airmate EGRD series of non-cyclic refrigerated dryers feature a controller that is designed to ensure optimum efficiency by automatically reducing the fan speed or stopping the fan depending on the condensing pressure and dryer temperature. An efficient rotary compressor also provides low specific power consumption, which further contributes to the overall energy efficiency of the dryers, while the inclusion of ELGi’s next-gen heat exchanger minimises the pressure drop and maximises thermal efficiency.

For maximum efficiency, the three-stage heat exchange system with cold storage allows the unit to cycle on and off as necessary. The efficient and compact heat exchanger is also able to operate effectively in high ambient temperatures, making it suitable for Australian conditions. Energy savings are also achieved through the inclusion of a zero loss drain which means that only condensate is drained with no air loss.

The Airmate EGRD 200 to 500 series models include a fixed speed, hermetically sealed and energy-efficient rotary compressor. Together key features such as a suction separator muffler, an internal protector, a reverse-phase protector in the three-phase variants, as well as a run capacitor contribute to the reliability of these compressors. A hot gas bypass valve prevents the freezing phenomenon in the heat exchanger.
