Design and Function
2.4
Material
For the outer housing, MEMMERT uses stainless steel (W.St.No. 1.4016), and for the interior,
stainless steel (W.St.No. 1.4301), which stands out through its high stability, optimal hygienic
properties and corrosion-resistance towards many (but not all!) chemical compounds (caution
for example with chlorine compounds). The chamber load for the appliance must be carefully
checked with respect to chemical compatibility with the materials mentioned.
A material resistance table can be requested from the manufacturer.
