Liebherr research and laboratory freezers
provide constant refrigeration performance
even in extreme climate conditions. The
use of ultra-modern components, efficient
and environmentally-friendly refrigerants
as well as precision controls ensures that
samples, chemicals and research materials
are stored optimally. Optional documentation
software continuously logs the temperature
profile – and if required, warning systems
alert the user when defined temperature
limits are exceeded.
Highly efficient with low energy consumption:
the precision electronic controller, the
dynamic refrigeration system and highly
effective insulation guarantee low operating
costs and are eco-friendly as well. The
high quality of the appliances guarantees
long life and reliable operation and
provides for economic and ecological
sustainability in laboratory and research
applications.
All laboratory appliances are designed
according to the ISO 60068-3 standard
with regard to maximum temperature
stability. They are specially constructed
for intensive professional use and feature
a very sturdy design – with highest-quality
materials and perfect workmanship right
down to the smallest detail. The exemplary
quality of the appliances is ensured by
elaborate tests. All electronic and
refrigeration components fulfill Liebherr's
stringent specifications to form a wellbalanced and therefore reliable system –
ideal for research and laboratory.
Hygiene plays a special role in research
and in the laboratory. That is why Liebherr
appliances are equipped with moulded
inner liners with large radii that are easy
to clean. Flush seals prevent condensation
and the accumulation of dirt and dust.
Sturdy castors also allow easy cleaning
of the floor space underneath the
appliances.
To meet the most stringent requirements
regarding reliability and accurate
temperature consistency in laboratory
applications, Liebherr appliances are
equipped with many useful features:
a visual and audible door alarm alerts
the user to undesired temperature
deviations. The appliances can be
connected via the volt-free contact to an
external remote warning system – and up
to 20 appliances can be networked with
a monitoring and alarm system via the
serial interface RS 485. In case of a
power failure, the Profi electronic
controller (in LKPv and LGPv) is powered
by a battery for 72 hours to prevent data
loss. The calibration option allows
precise temperature control adapted to
specific applications.
Durability and reliability are given top
priority in the material selection and
development of Liebherr laboratory
appliances. The exemplary quality and
easy usability of the appliances are
ensured by elaborate tests. In appliances
with a Profi electronic controller, the
refrigeration components are integrated
in the ceiling area, allowing easy access.
The practical door remains open at 90°
and is self-closing at less than 60° for
convenient use. And the sturdy inner
liners are easy to clean and allow
variable adjustment of the grid shelves.

Laboratory refrigerators and freezers with Profi electronic controller
The advantages at a glance
The refrigeration components are
securely integrated in the ceiling area,
allowing ready access.
The temperature can be set to
1/10 °C accuracy via the menu-guided,
multilingual Profi electronic controller
with integrated real-time clock.
The Profi electronic controller
has an integrated data memory for
temperature recording.
After a refrigerator or freezer door has been opened, a vacuum is built
up by air exchange – with the effect 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 laboratory appliances with a Profi electronic controller are equipped
with a volt-free contact for alarm forwarding to an external warning system.
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.
Maximum temperature stability in the interior is ensured by the dynamic cooling
system with double ventilation, in conjunction with optimal routing of the air flow.
Visual and audible door alarms alert
the user if the door is open for
longer than 1 minute.
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.
The smooth interior made
of 304-grade stainless steel
is easy to clean and enables
optimum hygiene.
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.
In laboratory appliances with a Profi electronic controller, 3-point
calibration enables temperature control adapted to the user.
To increase the net capacity of the inner liner, functional parts like fans and
evaporators are located outside the refrigerator compartment to save space.
The practical door remains open at 90 °
and is self-closing at less than 60 ° for
convenient use.
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.

Cal.1 1.0°C 0.5°C Cal.2 8.0°C -0.4°C Cal.3 15.0°C 0.8°C
Precision with 3-point calibration.
The laboratory appliances with a Profi electronic controller
have a 3-point calibration function for extremely accurate
temperature control. This permits compensation between the set
temperature and the actual internal temperature at as many
as three temperature points. Positive or negative changes to
the correction value can be made in steps of 0.1 K.
Mains-independent power supply of the electronic controller.
In case of power failure, the electronic controller is powered
by a battery. As a result, the memory continues to log the
internal temperatures without interruption for another 72 hours.
If external alarm and monitoring systems have been
connected, then data transfer to these is also maintained.
External temperature sensor.
The laboratory appliances have an access port (diameter
7.0 mm) in the appliance ceiling which allows a temperature
sensor to be positioned in the interior.
Advantage of hot gas defrost
It is quick, with minimal temperature rise.

External temperature and alarm documentation.
The laboratory appliances with a Profi electronic controller are
equipped with a volt-free contact for alarm forwarding to an
external remote warning system. The data can be read out of
the internal memory and transferred to a PC via an infrared
interface. In addition the appliances have an RS 485 interface
which enables as many as 20 appliances to be networked with
a central monitoring and alarm system.
08
Maximum temperature consistency.
Maximum temperature stability in the interior is ensured by the
dynamic cooling system with double ventilation. Very short
defrost cycles allow the internal temperature to be kept almost
constant during the defrost phases. All laboratory appliances
are designed according to the ISO 60068-3 standard with
regard to maximum temperature stability and consistency.
10 min
Hot gas defrost
Energy-efficient hot-gas defrost system.
Defrost less often and faster: the controller calculates the
optimum defrost cycles based on the compressor run-time.
Then the refrigerators defrost in just 8 minutes and the
freezers in just 12 minutes. The internal temperature is
slightly lowered shortly before so it remains almost constant
during the defrost cycle.
Versatile interior.
Sturdy and versatile: the U-shaped trayslides are heightadjustable – so refrigerated or frozen products of any kind can
be stored optimally on the plastic-coated grid shelves.
Hygienic benefit: the interior made of high-quality 304-grade
stainless steel is easy to clean thanks to the large corner radii.
