Technology

KDR’s patented innovation is a desiccant drum compressed air dryer for both oil-free and oil-flooded air compressors that uses no purge air, little or no power and be used for both built-in and stand-alone applications.

Its unique design means it can be built for small compressor applications (2KW and above) at low-cost. It is durable and quiet with none of the noisy venting of traditional twin tower desiccant dryers.

Unlike conventional refrigeration dryers the KDR dryer can be serviced by compressor service technicians and its unique changeable element will last 6000 hours. Compressor service technicians can change all parts of the unit. There is no refrigerant gas.

The KDR dryer as a built-in unit uses no power (working as a heat of compression dryer) whilst the stand-alone version has large power savings at part-load.

Being small and with few parts the KDR dryer is very cost competitive.

The drum dryer used in all KDR Compressors’ E-Save products is ASME and PED rated.

The structured honeycomb with ultra low pressure drop desiccant which fills the drums is of highest quality ensuring maximum adsorption to produce low dew points of down to -20℃. Along with delivering ultra dry air the desiccant is long lasting ensuring long intervals between replacement of spares.

The pneumatic arm which can be seen extending from the bottom left portion of the drum pictured is patented technology which allows the drum to make quarter turns on pneumatic energy alone. There is no other drum dryer in the world that turns in this manner.
