Description of the device
Heating system:
An air jacket heating is used for heating the work space. The ar-
rangement of the heating elements ensures that condensate for-
mation above the water reservoir is prevented as fast as
possible.
The outer door of the device is also heated. The heat radiated
onto the interior glass door/gas tight screen prevents condensate
formation. The work space of the device always remains visible,
despite high humidity.
Rear panel openings:

A sealable access port [1] allows cables, hoses or ad-
ditional sensors to be routed into the work space of the device.
A pressure compensation opening with insert [2] at the rear
panel of the device allows a compensation between the pres-
sures in the work space and in the operating room.
NOTE – Operating conditions
When accessories are to be operated in the
work space of the CO
2
incubator, the ambient
condition requirements must be observed (see
table below). The energy introduced into the
work space affects the beginning of the tem-
perature control range. When additional hea-
ting sources are introduced into the work
space, condensation (e.g. at the glass door)
may occur.
