Stirling Ultracold SU780XLE Ultra-Low Freezer

The Stirling Ultracold SU780XLE Ultra-Low Freezer delivers exceptional storage efficiency with a 780-liter capacity (27.5 cu. ft., 600-box) in an industry-leading compact footprint. Engineered for precision laboratory and biobanking applications, this unit maintains ±1°C temperature stability and offers the widest temperature range available: -20° to -86°C. Unlike conventional compressor-based systems, the SU780XLE features a proprietary Stirling engine with only two gas-bearing-supported moving parts—eliminating mechanical wear and contact during operation. This innovative design enables superior reliability, fastest temperature pull-down and recovery, and continuous adaptive control for optimal setpoint stability without on-off cycling. Additional features include 100% natural refrigerant cooling, universal voltage compatibility for any standard outlet, and an ergonomically redesigned handle and cabinet for laboratory environments. Built for demanding applications where sample integrity and equipment dependability are critical.
