Superior Stirling Engine Technology and Performance You Can Trust to Protect Your Precious Biological Samples

No Compressors to Fail

The biological materials stored in ULT laboratory freezers are incredibly valuable. And yet, researchers have trusted their priceless samples to failure-prone compressor-based technology for decades. Now there is a field-proven, cost-competitive alternative–the free-piston Stirling engine. With only two, non-wearing moving parts, our freezers offer a significant advancement in cooling technology. It’s simply a more reliable system design.

A Reliable Answer to Compressor Failure

Why Compressors Fail The Stirling Solution
Moving parts wear out Don’t wear out – gas bearings
Up to 24 moving parts to fail Only 2 moving parts
Oil lubrication management No oil
Compressor valves No valves
Start-stop operation Continuous operation with 100% adaptive control
On-off operation – surge currents No surge currents

Some in our industry have suggested that an ultra-low temperature freezer has to compromise reliability and performance to save energy. Nothing could be further from the truth with Stirling Ultracold. More than 13,000 Stirling engines have been incorporated into life science, university, biotech and pharmaceutical laboratory freezer equipment, including ULT freezers operating in over 300 research facilities. Stirling Ultracold’s technology has even been used by NASA on the Space Shuttle and continues to cool instruments on the RHESSI satellite.

Industry’s Best Performance and Cold Integrity

Revolutionary Ultra-Low Temperature Freezers

  • Lowest energy consumption
  • ± 1°C temperature stability in steady-state operation
  • 100% adaptive control, enabling faster temperature pull-down and door opening recovery
  • Most storage volume per square foot of floor space
  • Plugs into any outlet worldwide, including standard 110V
  • Slowest warm-up time
  • Modulated cooling, eliminates on/off cycling, improves reliability and quality of cold
  • Widest cooling temperate range, -20°C to -86°C

Industry-Leading Warranty

We understand how important ultra-low temperature storage reliability is to your research process. That’s why we cover our SU780XLE and SU105UE freezers with a limited warranty (U.S.A) that includes:

  • Two-year warranty for materials and labor*
  • Seven-year free-piston Stirling engine and thermosiphon parts
  • Extended warranty options
