Energy Efficiency

The RES, Thermal Mass Cycling Air Dryer is the perfect air dryer for dew point suppression with a varying air demand. A typical non-cycling air dryer will be at 90% of its full power even when the inlet capacity is at 10%.

A cycling air dryer has the ability to turn the refrigeration air compressor off to match the inlet capacity. Due to the thermal mass circuit, a cycling air dryer is able to cycle off and on. The thermal mass circuit is a reservoir, pump and additional heat exchanger filled with a water/glycol mixture. This thermal mass circuit acts as a buffer and stores the thermal heat energy until the refrigeration air compressor needs to turn on to cool the circuit down.

Example:

300 CFM Air Dryer operating 24 hours a day, 365 days a year.

Non-Cycling
8,000 hours x 3 KW x $.10 KW = $2,400 a year

Cycling Air Dryer only needs to operate when needed so it runs 1,000 hours.

Cycling
1,000 hours x 3 KW x $.10 KW = $300 a year

A cycling air dryer would save $2,100 a year. This is a significant savings.

Efficient Design

The Gardner Denver, RES air dryer components such as heat exchangers, refrigerant circuit, condensate separator and drain are readily accessible by removing the panels. The efficient design allows the need for additional floor space by integrated a Grade B (3 micron particulate /21ppm oil removal) pre-filter and providing the option of a cold coalescing filter – Grade E (0.01 micron particulate/0.008 ppm oil removal).
