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 lid-open
alarm delay can be adjusted between 1 and 5 minutes.
Additional safety is provided by a visual power failure alarm
and sensor defect alarm.
The Comfort electronic controller.
The precision Comfort electronic controller with digital
temperature display enables temperatures to be set accurately.
Symbols indicate the operating status of the appliance. To
ensure the level of hygiene required in the laboratory, the
electronic controller is fl ush-mounted and equipped with a
membrane keyboard.
External temperature and alarm documentation.
The laboratory chest freezers are equipped with a volt-free
contact for alarm forwarding to an external remote warning
system. In addition, they have an RS 485 serial interface for
central documentation of the temperature profi les and alarm
events.
Quality right down to the smallest detail
The Liebherr laboratory chest freezers up to -45°C are available in three different sizes and are specially designed for the
requirements in the research, laboratory, healthcare and industrial sector. The 1-point calibration ensures high temperature
Laboratory chest freezer up to - 45°C
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 chest freezers are equipped with 1-point
calibration 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.
StopFrost System.
The StopFrost system fi tted to the LGT models o ers several
key advantages: frosting of the freezer compartment and its
contents is reduced and the time-consuming process of
defrosting is necessary far less often. The vacuum is also
equalised after the chest lid is opened and closed so that the
laboratory chest can be re-opened e ortlessly.
External temperature sensor.
The laboratory chest freezers have an access port (diameter
10 mm) on the rear which allows temperature sensor to be
positioned in the interior.
Maximum temperature consistency.
The dynamic cooling system in conjunction with the precision
Comfort electronic controller ensures maximum temperature
stability. All laboratory chest freezers with a Comfort electronic
controller are designed according to the ISO 60068-3
standard with regard to optimum temperature consistency.
consistency. Integrated alarm systems and external temperature and alarm monitoring contribute to the safe storage of samples,
chemicals and research materials.
