Liebherr Ultra Low Temperature Freezers (ULT) - 491 Litres
Liebherr Ultra-Low Temperature Freezer (491 Litres) is a purpose-built freezer with low operating costs, sustainable cooling, a large interior with practical features and numerous safety functions. It sets the temperature range benchmark from -40 °C to -86 °C.
The Liebherr Ultra-Low Temperature Freezer is designed, engineered, and made in Austria with high-quality materials and meets the stringent requirements for safety and temperature consistency to meet the demanding requirements of laboratories and scientific institutions. The precision electric controller allows the user to set accurate temperature settings and highly effective insulation. It has an integrated visual and audible alarm system to warn of unusual temperature deviations.
The Liebherr Ultra Low Temperature Freezers (ULT) has world-class temperature stability, like all Liebherr MediLine Biomedical Fridges and Freezers do. They are tested at state-of-the-art Liebherr Biomedical Development Facilities according to Procedure EN 60068-3, which involves measuring temperatures at nine different points in the interior.
Liebherr is environmentally friendly and promotes sustainability, having minimal greenhouse effect and no potential for ozone depletion using only R170 & R290 Refrigerants which also offers outstanding energy efficiency.
Efficient Freezing System
Energy consumption and operating costs are significantly reduced as Liebherr uses only premium-quality compressors, condensers, evaporators and other components.
The Liebherr Ultra-Low Temperature comfort electronic controller lets users set temperatures to 1/10°C accuracy using the membrane keypad and digital display.
Advanced Alarm System
Audible and Visual Alarms alert users of temperature breaches, power failure and when the door is ajar for more than 1 minute. The fridges are also equipped with a volt-free alarm contact for alarm forwarding to remote monitoring systems.
The built-in alarm test function can check whether an internally or externally connected alarm system is functioning correctly without affecting the refrigeration performance.
A highly efficient cooling system and compressor ensure temperature uniformity and fast temperature recovery after openings.
The temperature stability is tested in state-of-the-art facilities according to EN 60068-3, which involves measuring temperatures at nine different points in the interior.
Serial Bus Interface
Liebherr Biomedical Fridge and Freezers comes preconfigured with a serial bus interface which can be used to connect to an external monitoring system. In the event that a monitoring system is unable to connect to the built-in interface, an interface converter retrofitting kit that can be connected to a PC or Laptop is available. The serial bus interface can be used to connect up to a network of 20 appliances. Their temperature and alarm can be recorded utilising Liebherr’s Temperature Monitoring Software available for Windows PC.
Environmentally Friendly Refrigerants
Liebherr uses refrigerants R170 and R290, which are environmentally friendly – they have minimal greenhouse effect and no potential ozone depletion replacing those previously used (R134a and R404a). All Liebherr Ultra Low Temperature Freezers use R170 and R290 as refrigerants and offer outstanding energy efficiency, improving Carbon Dioxide footprint and promoting sustainability. Liebherr has been awarded the EcoVadis Silver Medal twice as a sustainable brand.
