Design and description 2.2 Description The constant climate chamber can heat the interior up to 70 ºC and cool it down to 5ºC. For this purpose, low-noise, long-life and energy-saving Peltier cooling and heating technology is used. In heating operation, a part of the required energy is extracted from the surroundings (heat pump principle). Humidity in the interior can be regulated between 10 and 90 % rh (rh = relative humidity).
Design and description Range A: In this range, temperature and humidity can be combined as you please, without resulting in any significant condensation. If there are extreme ambient conditions, the working range may be restricted. Range B: If the specified range is exceeded upwards, 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.
