Construction and description
2.2 Construction and function
The appliance can heat up the interior to up to 60 °C and cool it down to –10 °C (without
humidity and without light) or +10 °C (with humidity). A compressor is used for cooling.
Humidification of the interior is achieved by evaporating water from a tank at a set rate by
means of a hot-air generator on the rear side of the appliance. The sterile hot air is introduced
into the interior above the fan and mixed with the air current. Humidity is reduced through
condensation, using Peltier cooling modules on the rear side of the appliance. Ice that might
build up due to dehumidification is automatically defrosted in cycles.
The model ICH L / ICH L eco is equipped with an illumination box in the upper interior, which
contains fluorescent tubes. The chamber load can be illuminated with UV light and/or day-
light.
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.
