The LIEBHERR LGT 3725 Low-Temperature Laboratory Chest Freezer is designed and manufactured in AUSTRIA to the highest standards and are ideal for use in laboratories and research facilities.

Key Features are:

  • Low temperature range -10°C to -45°C
  • Capacity 350 litres
  • ENERGY EFFICIENT only 1069 kWh /year
  • Integrated alarms and data memory
  • External temperature and alarm documentation
  • Stop Frost system allows lid to be re-opened effortlessly
  • HACCP compliant electronic controller
  • Made in AUSTRIA – 24 Months Warranty


The StopFrost system fitted to the LGT models reduces frosting of the interior and the freezer contents – so the time-consuming process of defrosting is necessary far less often. The vacuum is also equalised quickly after the lid is opened and closed so that the chest can be re-opened effortlessly.

Comfort Controller

Precision Comfort electronic controller with digital temperature display for accurate temperature setting. Thanks to its position on the chest rear, the electronic controller can be connected to external systems. The precision Comfort electronic controller ensures maximum temperature stability and high-temperature consistency in the interior.

Integrated Alarm Systems

Visual and audible temperature alarms alert the user if temperature deviation limits are exceeded. The parameters for the temperature alarm can be individually set. The integrated data memory with min/max temperatures in the Comfort electronic controller logs possible temperature fluctuations with date, time and duration of the alarm. In addition, the electronic controller ensures high-temperature consistency in the interior. All laboratory chest freezers are tested and approved in accordance with ISO 60068-3

Integrated Data Memory

The Comfort electronic controller has an integrated data memory. It logs the maximum and minimum internal temperatures that occurred once the set temperature was reached, the last three temperature alarms and power failures, together with the time, date and duration of the alarm. The respective data can be recalled using the AlarmLog function and read on the display panel.

1-point calibration

The laboratory appliances with Comfort electronic controllers provide 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 0.1K.

Interior Lighting

The lid has an integrated, energy-efficient LED interior light to improve visibility 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 tested and approved according to the ISO 60068-3 standard with regard to optimum temperature consistency.
