2. Description and function
2.1 Description
The appliance can heat the interior up to 35 ºC and cool it down to 0 ºC. In addition to
the HPP standard equipment, the appliance features an exhaust air unit in the back of the
chamber and 4 swivel-type LED light strips for adjusting the interior lighting in steps of 1%. In
addition, the temperature-humidity working range (see chapter 2.2) can be enlarged by con-
necting it to a central compressed air supply (see page 11).
2.2 Working range
The temperature-humidity diagram (Fig. 2) specifies at what range of temperature and humid-
ity a permanent, condensation-free operation is possible.
By connecting it to a central compressed air supply, the temperature-humidity working range
of the appliance can be extended by the use of external compressed air. This makes dehumidi-
fication of the air in the appliance possible even at 10 ºC down to 10 % relative humidity:
Caution:
If the chamber is in operation at the upper limit or outside the working range for long
periods, puddles of water may form inside the chamber and water may force its way out
of the door seal.
