3.2 Purpose
The laboratory refrigerator and the laboratory freezer are equipped
with an explosion-proof interior (hereafter referred to as “potentially
explosive area”). The laboratory refrigerator and laboratory freezer
are used for commercial storage of biological and chemical sub-
stances. The laboratory refrigerator and the laboratory freezer are
not medical products.
Storing your sensitive and highly flammable substances requires
cooling that is both precise and safe. Our LABEX
®
models are spe-
cially developed for these requirements and meet the highest
safety requirements, as verified by TÜV SÜD on the basis of nor-
mative European principles.
Our LABEX
®
models are specially designed for storing explosive
substances. You can rely on the quality of our products:
n Due to the construction, sparks cannot develop.
n The interior is free from any ignition sources.
n The structural safety of all mechanical components has been
proven.
n The power circuits in the refrigerator interior are subject to
energy restrictions.
n The temperature sensors are protected by appropriate safety
barriers.
n The recirculating blower is galvanically protected by a safety
power pack.
n Earthing of the entire refrigerator interior ensures equipoten-
tiality.
n The machine room is specially sealed off from the interior con-
tainer.
n Vacuum compensation for the refrigerator interior is provided by
a controlled ventilation valve.
n Only plastics with proven conducting properties are used in the
interior.
n The interiors have been checked for freedom from ignition
sources in line with Directive 2014/34/EU.
