Construction and description
2.2 Function
Appliances of the SNxxplus
type series feature natural
circulation (convection).
For the SFxxplus type series,
air is circulated by a fan on
the rear panel of the interior
chamber (Fig. 3, No. 1). It
increases the air flow and
provides stronger horizontal
forced air circulation than
natural convection.
In both the convection and
fan ventilated appliances,
supply air (2) is preheated
in a pre-heating chamber
(3). Through the ventilation
slits in the side panel of the
working chamber, the pre-
heated air is introduced into
the interior of the chamber.
The supply and exhaust air
(5) volume (air change) is
controlled by the air flap
(4) on the rear panel of the
appliance.
2.3 Material
For the outer housing,
MEMMERT deploys stain-
less 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 towards many (but not all!) chemical compounds (caution for exam-
ple 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.
2.4 Electrical equipment
►Operating voltage and current consumption: See nameplate
►Protection class I, i.e. operating insulation with PE conductor in accordance with EN 61010
►Protection type IP 20 acc. to EN 60 529
