Construction and description
2.2 Description
The appliance can heat the working chamber up to 70 °C (IPP) or 45 °C (IPS) and cool it
down to 0 ºC (IPP) or 14 °C (IPS). Low-noise, long-life and energy-saving Peltier cooling
and heating technology is used for this. In heating operation, a part of the required en-
ergy is extracted from the surroundings (heat pump principle). Condensation formation
during the cooling down process takes place outside the working chamber on the Peltier
element
Optionally, the appliance can be equipped with a light module.
2.3
Material
For the outer housing, MEMMERT deploys 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 compatibil-
ity 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
impedance 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 com-
pany what the system impedance is.
Observe the country-specific regulations when connecting (e.g. in Germany
DIN VDE 0100 with residual current circuit breaker).
