Ultra-low temperature freezer featuring the free-piston Stirling engine. This next generation of environmentally sustainable ULT freezers achieve stable storage conditions over a wide temperature range. The freezer uses 70 to 75% less energy than standard compressor-based ULT freezers, with the industry's best ultra-low cooling performance.

±1 °C 'steady state' temperature variation over time
Faster initial pull down, ambient to –80 °C, <6.5 hours
Faster door opening temperature recovery, 35 minutes to –80 °C (ENERGY STAR® final test method)
Slowest warm up time, 2.5 hours from –80 to –60 °C
Largest storage capacity per square metre of floor space
Plugs into any outlet
These upright freezers feature a 780 litre cabinet that delivers stable, uniform –86 °C storage at a fraction of the operating cost of conventional cascade refrigeration systems. The SU780XLE models combine the performance of a free-piston Stirling engine with an efficient, thin wall, high performance vacuum insulated panels and non HFC polyurethane foam using the Ecomate® environmentally friendly blowing agent. The Stirling engine’s continuous modulation and fully adaptive capabilities eliminate the on-off cycling operation of compressor-based systems. This delivers uncompromising cooling performance and reliability with unmatched energy efficiency. With its 780 litre, 600×2 ml box storage capacity, the SU780XLE stores ⅓ more samples per square metre of floor space than comparable models, in addition to providing the industry’s widest cooling temperate range of –20 to –86 °C. Secure touch pad inputs allow access to programming for all control functions and alarm set points.

The SU780XLE models have an auto-voltage range of 100 to 240 V (±10%) at either 50 or 60 Hz (automatically adjusts). This auto-voltage capability allows SU780XLE models to operate on any outlet without factory modification (the user will need to install the specific cord that fits their receptacle). SU780XLE units come with five shelves, as well as Type-E (EU-plug); Type-G (UK-plug); and Type-J (CH-plug) power cords (220 to 240 V).

Certifications: cULus, and ENERGY STAR® certified.
