  • Plugs into any outlet

This next generation of environmentally sustainable ULT freezers achieve stable storage conditions over a wide temperature range.

These upright freezers feature a 780 l (27.5 cu.ft.) 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 unique 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 l (27.5 cu. ft.), 600 2 ml box storage capacity, the SU780XLE stores ⅓ more samples per square foot of floor space than comparable models, in addition to providing the industry’s widest cooling temperate range of –20 to –86 °C. Secure touchpad inputs permit access to and programming for all control functions and alarm setpoints.

The SU780XLE models have an auto-voltage range of 100 V to 240 V (±10%) at either 50 or 60 Hz (automatically adjusts). This auto-voltage capability allows the SU780XLE models to operate on any outlet without factory modification (the user will need to install the specific cord that fits their receptacle). The SU780XLE units come with both a NEMA 5-15P plug that requires standard NEMA 5 - 15R receptacle (120 V) and a NEMA 6-15P plug that requires standard NEMA 6 - 15R receptacle (240 V).

The freezer uses 70 to 75% less energy than a standard compressor-based ULT freezer, with the industry's best ultra-low cooling performance.
