Immense manufacturing know-how and outstanding material knowledge lies behind the unique Memmert heating system, continually improved over decades. The equipment chambers, made of stainless steel, are deep drawn in fully automatic production facilities, and form the technical basis for the protected placement of heating elements on the four sides of the working chambers of the universal ovens, incubators and sterilisers. In the CO₂ incubators and HCP humidity chambers, the doors and rear wall are heated as well. The unbeatable advantages of the Memmert heating system:

• The heating elements are protected, yet still lie close to the chamber load
• No corrosion or furring of heating elements
• Working chamber easy to clean, as it has no spaces or corners difficult to access
• The direct contact between the heating ribs and sliding shelves guarantees an excellent thermal transfer, and thus an improved temperature uniformity
• The arrangement of heating elements around the interior ensures optimal temperature uniformity throughout the chamber (even when heavily loaded)
• The excellent thermal conductivity of the aluminium sheets attached to the outer side of the chamber additionally optimises temperature uniformity and heat accumulation (e.g. in case of mains failure)
• Heat is distributed homogenously in the chamber in three ways: Heat conduction through the material, thermal radiation from the surfaces, and convection (natural as well as forced air movement)

In the waterbaths the heating elements also lie in deep drawn ribs protected from wetness and furring. Through this type of construction (heating elements in the floor and side walls), natural turbulence is created, providing optimal temperature uniformity in the bath.
