GXR Series

Gardner Denver Authorised Distributor

GXR Series – Refrigerant Air Dryers 2.5 to 18.0 m3/min

Advanced Design

Using advanced heat exchanger, separation and refrigeration technology, the GXR series refrigerant dryer delivers dependable operation and optimum performance. It’s intelligent design reducing life cycle costs and makes installation a breeze.

Design Features

Stainless steel heat exchanger

Compact and thermally efficient the stainless steel brazed plate heat exchanger is corrosion resistant and ensures air quality and long term performance.

Environmentally friendly

Energy efficient operation and use of ozone friendly refrigerants reduce the GXR series refrigerant dryer’s environmental impact.

Optimal dew point

Best possible dew point performance under all conditions delivers dependable high quality compressed air.

Low pressure drop

The design of the brazed plate heat exchanger and integral separator ensures minimal pressure drop, improving system performance and reducing operating costs.

Dryer Operation

Warm saturated air from the compressor enters the air to air heat exchanger where it is cooled by the air exiting the refrigerant dryer. This precooled air then enters the air to refrigerant heat exchanger and is further chilled, causing water vapour in the air to condense. Condensed moisture is collected from the air stream by an integral separator with a stainless steel demister.

Liquid condensate is removed from the separator by an automatic timed electric drain. Cool dry discharge air then enters the re-heater where the elevated refrigerant temperature warms the discharge air, preventing condensation forming on outlet piping.
