The especially precise, environmentally-friendly, energy-saving heating and cooling system with Peltier technology is used in the cooled incubator IPP, the constant climate chamber HPP and the storage chamber IPS. Heating and cooling in a single system: If a voltage is placed across a Peltier element, one side is cooled and the opposite side simultaneously heats up. Simply by reversing the polarity of the supply voltage, the hot and cold sides of the Peltier element can be swapped.
The Peltier technology works in a particularly economical and energy-saving manner at temperatures close to ambient temperature, since energy is only required if heating or cooling is needed, in contrast to compressor technology. Very fine adjustments can be made here to the heating or cooling functions.
In heating operation, in the same way as in a heat pump, thermal energy is removed from the ambient air and introduced into the inner chamber. Because of the closed Peltier cooling system, no outside air is exchanged. The advantages: No de-humidification of the inner chamber and a notably reduced risk of contamination.
