The advantages at a glance
The Profi electronic controller
has an integrated data memory for
temperature recording.
The
refrigeration components
are
securely integrated in the ceiling area,
allowing ready access.
Laboratory appliances with a
Profi electronic controller are
equipped with an access port
(7.0 mm in diameter) in the ceiling
area to enable connection of an
independent temperature sensor.
In case of power failure, the electronic controller is immediately powered by an
integrated 12 V battery. As a result, the integrated memory continues to log
the internal temperatures without interruption for another 72 hours.
To increase the net capacity of the inner liner, functional parts like fans and
evaporators are located outside the refrigerator compartment to save space.
Laboratory refrigerators and freezers with Profi electronic controller
The smooth interior made
of 304-grade stainless steel
is easy to clean and enables
optimum hygiene.
The practical door remains open at 90 °
and is self-closing at less than 60 ° for
convenient use.

The temperature can be set to
1/10 °C accuracy via the menu-guided,
multilingual Profi electronic controller
with integrated real-time clock.
Maximum temperature stability in the interior is ensured by the dynamic cooling
system with double ventilation, in conjunction with optimal routing of the air fl ow.
After a refrigerator or freezer door has been opened, a vacuum is built
up by
air exchange – with the e ect that the door is hard to reopen
immediately afterwards. The integrated pressure relief valve ensures
that the vacuum is quickly equalised so that the door can easily be reopened.
The hot-gas defrost system with demand and time control permits very short
defrost cycles: 8 minutes for laboratory refrigerators, 12 minutes for laboratory
freezers. To additionally improve temperature stability during defrost, the internal
temperature is lowered by 1 °C (refrigerators) or 2 °C (freezers) shortly before.
The laboratory appliances with a Profi electronic controller are equipped
with a volt-free contact for alarm forwarding to an external warning system.
Visual and audible door alarms alert
the user if the door is open for
longer than 1 minute.
The LKPv and LGPv ranges come with
castors as standard to allow versatile
use depending on the available space
and convenient cleaning also underneath
the appliances.
In laboratory appliances with a Pro electronic controller, 3-point
calibration enables temperature control adapted to the user.
