The Liebherr LKPv 6523 offers more than 600 liters of cooling space for medical and laboratory use. The temperature range is 0 ° C to + 16 ° C, the digital display is accurate to 0.1 ° C. The door is fitted with insulating glass, the LED ceiling lighting can be switched on separately.
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.
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.
72-hour power failure monitoring.
In the event of a power failure, the electronic system is powered by an integrated 12V battery. The temperature trend is registered for 72 hours and, if available, an alarm signal is passed on to the central control room.
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.
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.
