Dry air output to better than -40 Celsius 19" Rack Mount Dehydrator Type 6251/6252
Low noise levels & minimum vibration
Digitally controlled alarms
Wet air by-pass fail safe
Oil-less air compressor


This automatic pressurising dehydrator has been designed to operate under very arduous conditions, it has been tested to IEC standards in vibration, Shock, Bump, Free Fall, Dry Heat, Cold, Change of Temperature and humidity. Routine maintenance is minimised by the use of an automatically regenerated molecular sieve. Scheduled maintenance intervals are only required after 2500 hours of compressor run time, with a typical duty cycle of 5% - 10% this unit is cpable of running for prolonged periods without intervention. The standard unit is fitted with an air receiver tank in series with the dry air output, the pressure in this tank is sensed by the control electronics, closed loop control of the compressor ensures that this pressure is maintained at a preset level. The final output pressure is adjusted by a pressure regulator mounted on the front panel. Types 6251 & 6252 only differ in terms of front and rear connections, the 6251 interfaces via the front panel and the 6252 via the rear.
