Construction and description
2.2 Description
The appliance can heat the interior up to 60 °C and cool it down to 15 °C. Low-noise, long-life
and energy-saving Peltier cooling and heating technology is used for this. In heating opera-
tion, a part of the required energy is extracted from the surroundings (heat pump principle).
Additionally, the humidity in the interior can be regulated. The humidity is increased by the
evaporation of water from a tank which is then fed into the interior and reduced by conden-
sation on a Peltier module.
2.3
Material
For the outer housing, MEMMERT uses stainless steel (Mat.No. 1.4016 – ASTM 430) and for
the interior, stainless steel (Mat.No. 1.4301 – ASTM 304) is used, which stands out through
its high stability, optimal hygienic properties and corrosion resistance to many (but not all!)
chemical compounds (caution for example with chlorine compounds).
The chamber load for the appliance must be carefully checked for chemical compatibility with
the materials mentioned. A material resistance table can be requested from the manufacturer.

Connections and interfaces
2.5.1
Electrical connection
This appliance is intended for operation on an electrical power system with a system imped-
ance Z
max
of a maximum of 0.292 ohm at the point of transfer (service line).
The operator must ensure that the appliance is operated only on an electrical power system
that meets these requirements. If necessary, you can ask your local energy supply company
what the system impedance is.
Observe the country-specific regulations when making connections (e.g. in Germany
DIN VDE 0100 with earth leakage circuit breaker).
