LIEBHERR SUFsg 5001 Ultra Low Temperature Upright Freezer 491 Litre with electronic controller
Liebherr's ultra-low temperature freezers (ULT) are the gold standard in the –40 °C to –86 °C temperature range, offering the safety, performance and ease of use.
Alarm messages in critical situations
Don't worry about security: Thanks to a threestage monitoring system, consisting of integrated alarm messages for temperature, door or mains faults, upgradable features such as CO2 emergency cooling, and online monitoring ensure the very best protection for your stored samples at all times. In the event of a power failure, integrated 12-volt batteries immediately supply the electronics with power. You will also be notified in critical situations so that you can quickly rectify the fault.
Mechanical key lock
The mechanical key lock protects the stored products from unauthorised access. The door is opened with an ergonomic and unbreakable aluminium lever handle.
Minimal temperature fluctuations
The Liebherr ultra-low temperature reezers have the lowest possible fluctuations both internally, within the appliance, and over time.
Low heat emission
Compared to older technologies, the efficient cascade cooling system, with HC refrigerants generates significantly less heat. This saves costs in the thermal design of the room’s air conditioning system.
Low energy consumption
Ultra-low temperature freezers are among the appliances with the highest energy consumption in research facilities. Liebherr ultra-low temperature freezers are among the most economical models on the market worldwide.
For remote monitoring, all appliances are equipped with volt-free contacts and ethernet interfaces. The temperature and alarm records can also be read via the integrated USB interface.
