For your highly flammable products
The Liebherr LKexv 3910 in explosion-proof version offers 360 liters of cooling space with a temperature range of + 3 ° to + 16 ° C. The self-closing door and the five adjustable glass shelves are practical to use. The temperature is displayed digitally and can be set accurately to 0.1 ° C.
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 a 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.
Protected against freezing.
The safety thermostat protects stored samples and medicines from freezing. In the event of a defect, the safety thermostat prevents the interior temperature from dropping below + 2 ° C.
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 °.
The relay contact can be connected to a central log or alarm system that can alert security personnel or caretaker outside working hours, for example. Warnings with optical or acoustic alarm are possible.
With left or right opening door.
With the option to change the door 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.
