Integrated alarm systems.
Visual and audible alarm systems alert the user to undesired
temperature deviations or when the door is open. All alarm
parameters can be individually set. For example, the door-
open alarm delay can be adjusted between 1 and 5 minutes.
Furthermore, the laboratory appliances with a Comfort
electronic controller have a visual power failure alarm and a
sensor defect alarm.

Liebherr offers refrigerators and freezers with a Comfort electronic controller and spark-free interior especially for storing explosive
and highly flammable substances in the chemical industry. The inner liners meet the safety requirements of the EU Directive 94/9 EG
Laboratory refrigerators and freezers with Comfort electronic controller and spark-free interior
The Comfort electronic controller.
The precision Comfort electronic controller with digital
temperature display enables temperatures to be set accurately
to 1/10 °C. Symbols indicate the operating status of the
appliance. The electronic controller is fl ush-mounted and
equipped with a membrane keyboard for perfect hygiene.
Certifi ed according to ATEX 95.
All appliances with spark-free interior are tested according to
the 94/9 EC (ATEX 95) Directive. Rated as II 3G Ex nA II T6,
these appliances are suitable for storing explosive and highly
fl ammable substances in sealed containers.
Integrated data memory.
The Comfort electronic controller is equipped with an integrated
data memory which logs the maximum and minimum internal
temperatures as well as the last three temperature alarms
and power failures, together with the time, date and duration.
These data can be read out on the display.

Accurate 1-point calibration.
The laboratory appliances with a Comfort electronic controller
have a 1-point calibration function for accurate temperature
control. This permits compensation between the set temperature
and the actual internal temperature. Positive or negative changes
to the correction value can be made in steps of 0.1 K.
External temperature and alarm documentation.
The laboratory appliances are equipped with a volt-free
contact for alarm forwarding to an external remote warning
system, as well as with a serial interface RS 485 which
enables central documentation of temperature profi les and
alarm events. LTM monitoring software is optionally available.
Maximum temperature consistency.
Maximum temperature stability is ensured by the cooling systems
of the laboratory refrigerators and freezers in conjunction with
the precision Comfort electronic controller. The refrigerators are
equipped with a safety thermostat to prevent temperatures
below +2 °C in case of a fault. All laboratory appliances with
a Comfort electronic controller are designed according to the
ISO 60068-3 standard with regard to maximum temperature
stability and consistency.
Sturdy glass shelves.
The sturdy glass shelves are easily adjustable in height and can
conveniently be removed at a door opening angle of 90 °. They
ensure secure positioning of the refrigerated or frozen products
and have a loading capacity of up to 40 kg in the refrigerator
compartment and up to 24 kg in the freezer compartment.
External temperature sensor.
The laboratory appliances with a Comfort electronic controller
have an access port (diameter 10 mm) on the rear which
allows the temperature sensor to be positioned in the interior.
(ATEX 95)
and have been tested according to the EN 1127-1, IEC 60079-0 and IEC 60079-15 standards by electrosuisse – SEV
(Swiss Association for Electrical Engineering, Power and Information Technologies), an approved ATEX conformity evaluation organisation.
