GXT Series

Gardner Denver Authorised Distributor

GXT Series – Refrigerant Air Dryers 24.0 to 90.1 m3/min

Reliable Efficiency

With an advanced stainless steel heat exchanger and low maintenance design, the GXT series high capacity refrigerant dryer will continue saving you money year after year. Offering outstanding electrical power savings and reduced operating costs it’s the ultimate energy efficient refrigerant dryer solution.

Design Features

Stainless steel heat exchanger

Not only durable, the corrosion resistant and thermally efficient stainless steel brazed plate heat exchanger will ensure air quality and long term performance.

User friendly control

Standard with an integral fully automatic controller with LED display. The GXT series dryer optimises energy usage by intuitively adapting to system needs.

Environmentally friendly

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

Rugged design

Built with quality components and housed in an epoxy coated galvanised cabinet, the GXT series refrigerant dryer is made to last.

Dryer Operation

Warm saturated air from the compressor is rapidly chilled in the air to air heat exchanger by the cold air exiting the air to refrigerant heat exchanger.

Precooled air then enters the air to refrigerant heat exchanger and is further chilled, causing water vapour in the air to condense.

A moisture separator lowers the velocity of the air and mechanically separates condensate from the air stream. Liquid condensate is removed from the separator by an automatic timed electric drain.

Cool dry discharge air then re enters the air to air heat exchanger where incoming air warms the discharge air, preventing condensation forming on outlet piping.

Correction factors2

To calculate drying capacity for specific conditions, multiply the volume flow capacity by the correction factors (volume flow x A x B x C).
