Liebherr MediLine with air cooling - SUFsg 7001

Ideal for research work in laboratories: this ultra-low-temperature freezer delivers maximum performance reliably in a temperature range from –40 °C to –86 °C. The temperature stability and consistency is tested and guaranteed in accordance with the test procedure EN 60068-3.

MAIN FEATURES:

Environmentally friendly refrigerants
Liebherr appliances are optimised for maximum energy efficiency and low operating costs. We only use the natural and environmentally-friendly refrigerants R 600a and R 290. When used with highly efficient compressors, these are extraordinarily efficient and, with their low global warming potential, also future-proof.

Efficient refrigeration system
Liebherr guarantees the outstanding quality of its refrigeration systems through expertise derived from decades of experience in the refrigeration technology sector, and through continuous research and development. By employing only premium-quality compressors, condensers, evaporators and other refrigeration components the energy consumption and operating costs of Liebherr appliances are significantly reduced.

Alarm test function
This test function can be used to check whether an internally or externally connected alarm system is functioning correctly. The appliance’s refrigeration performance is not affected by this test.

Monitoring system
The three-stage monitoring system consisting of integrated alarm notifications for temperature, door or mains electrical faults, upgradable features such as CO2 emergency cooling and online monitoring, ensure the very best protection for your stored items. In the event of a power failure, integrated 12-volt batteries immediately supply the electronics with power. Notifications are provided in critical situations.

Cover for mains switch incl. key lock
Protection against unintended disconnection or manipulation of the mains switch

Foamed inner doors
The foamed inner doors provide the best possible insulation and temperature stability, ensuring efficient cooling and low power consumption.

Stainless steel workmanship
The interior, shelves and inner doors are made of rust-proof stainless steel and are therefore easy to clean. This enables optimum hygiene.

Mechanical lock
The mechanical key lock protects the stored products from unauthorised access. The door is opened with an ergonomic and unbreakable aluminium lever handle.

Temperature stability and consistency EN 60068-3
All laboratory refrigerators and freezers are tested at the state-of-the-art Liebherr development facilities according to procedure EN 60068-3 for measuring temperature stability. This involves measuring the temperature at nine different points in the appliance interiors.

Set of cryoboxes
The set contains 36 durable and temperature-resistant cryoboxes made from water-repellent cardboard, with fixed 9x9 grid, for safe storage and transport of valuable samples.

Temperature alarm
The integrated temperature alarm indicates if the lower or upper alarm thresholds have been breached. It uses both acoustic and visual signals to provide maximum security for goods that have been stored.
