Very spacious freezer for your valuable products
The Liebherr LGPv 1420 offers more than 1400 liters of freezer space for medical and laboratory use. The temperature range is -10 ° C to -26 ° C, the digital display is accurate to 0.1 ° C. The cabinet has various alarm systems and the date, time and temperature are saved every 4 minutes.
NoFrost-Pro: fast and energy-efficient defrosting.
Demand-controlled hot gas defrost prevents unnecessary defrosting and thus waste of energy. This highly efficient defrosting method guarantees a short defrosting time of approx. 10 minutes. During defrosting, hot gas generated by the cooling process is released and the ice is thawed on the evaporator. This minimizes the temperature rise in the unit during defrosting, resulting in greater temperature stability and consistency.
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 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.
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 concierge, for example, outside working hours. Warnings with optical or acoustic alarm are possible.
Audible warning in case of failure.
When the temperature rises above the set value, you will be warned by an acoustic signal.
