Construction and description
2.3
Working range of constant climate chambers HPPeco
The temperature-humidity diagram speci
fi
es at what range of temperature and humidity
a permanent, condensation-free operation of the constant climate chamber HPPeco is
possible.
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.
Climate points in the threshold range of the climate diagram can only be reached
with the correct dehumidi
fi
cation time interval. For optimal time interval setting, see
chapter 7.3.7

■
Range A:
In this range, temperature and humidity
can be combined as you please, without
resulting in any signi
fi
cant condensation.
In extreme ambient conditions, the work-
ing range may be restricted.

■
Range B:
If the speci
fi
ed range is exceeded up-
wards, e.g. 80 % rh at 60 °C, the hot
steam fed in will immediately condense,
due to the dew-point, at the coldest point
in the appliance.
■
Range C:
At low temperatures and low relative air
humidity, the effective range is heavily
dependent on the degree of humidity of
the chamber load.
