Construction and description
2.3 Function
Appliances of the UN...
and IN... type series feature
natural circulation (convec-
tion). For the UF... and IF...
type series, air is circulated
with a fan at the working
chamber rear panel (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.
2.4 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 towards 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.
2.5 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
►Interference suppression acc. to EN 55011 class B
►Appliance fuse: Fusible link 250 V/15 A quick-blow
►The temperature controller is protected with a miniature fuse 100 mA (160 mA at 115 V)

age medium to the appliance (see page
52).
►export protocol logs from the appliance
to a USB storage medium (see page
54).
►transfer user ID data stored on a USB storage medium to the appliance (see page 55).
The USB interface is located on the lower right of the ControlCOCKPIT (Fig. 4).
Ethernet interface
Via Ethernet interface, the appliance can be
connected to a network, so that you can
transfer programmes created with Atmo-
CONTROL software to the appliance and read
out protocol logs. The Ethernet interface is
located on the rear of the appliance (Fig. 5).
For identification purposes, each appliance
connected must have its own unique IP ad-
dress. Setting the IP address is described on
page 44.
