Explosion proof. Also under the worktop

The Liebherr LGUex 1500 in explosion-proof version offers 139 liters of freezer space with a temperature range of -9 ° C to -26 ° C. Version with double alarm and potential-free contact, the highest and lowest temperatures can be read on the display for a maximum of 40 days.

Temperature stability IEC 60068-3

All Liebherr laboratory refrigerators and freezers are tested in the modern Liebherr Research & Development center according to the IEC 60068-3 procedure for measuring temperature stability.

ATEX 114 Explosion proof

The explosion-proof interior has been tested in accordance with EU Directive 2014/34 / EU (ATEX 114). Due to the classification II 3G Ex nA II T6, this model is suitable for the storage of explosive and highly flammable substances in closed containers.

Additional temperature control possible.

An opening (Ø 7.6 mm) is provided at the top of the interior, which offers the option of feeding through an external temperature sensor or another measuring connection.

Alarm on demand.

An optical and acoustic temperature alarm warns of an unwanted temperature change of 2K. The alarm limit can be adjusted if necessary.

Extremely accurate temperature.

The laboratory devices with Profi electronics have 1-point calibration for extremely precise temperature control. This allows compensation between the set and the actual interior temperature. The correction value to be set can be changed in steps of 0.1 ° C.

A good memory for temperatures.

The minimum and maximum indoor temperatures are stored and can be read out at any time over a period of 41 days.

Self-closing door.

The self-closing door prevents unnecessary loss of cold air and thus helps to save energy costs. The door remains open at an angle of 90 °, but will close automatically from 75 °.

Remote monitoring.

The relay contact can be connected to a central logging or alarm system that can alert security personnel or caretaker, for example, outside working hours. Warnings with optical or acoustic alarm are possible.

With left or right opening door.

With the option to change the door hinging direction, the cabinet is always easily accessible. All household models are factory-fitted with right-hinged doors and are prepared for hinge exchange.

Audible warning in case of failure.

When the temperature rises above the set value, you will be warned by an acoustic signal.
