HPP constant climate chamber with compressed air
dehumidification

In this special variation, the temperature-humidity working area of the appliance is extended
by the use of external compressed air. This makes it possible to dehumidify the air in the appli­ance even at 10 ºC down to 10 % relative humidity:

In order to do this, connect a suitable
pressure hose at the rear of the chamber
(see picture) to an external compressed air
supply (max. 5 bar).

Temperature °C

Only oil-free compressed air may be
used.

If 10 % humidity is not attained at 10 ºC,
the compressed air is not, or not sufficiently,
pre-dehumidified. In this case it is possible
to dehumidify the compressed air before it is
fed into the chamber via a maintenance unit
connected upstream, available from MEM-
