Stirling Ultracold’s Breakthrough Cooling Technology

Stirling’s breakthrough cooling technology makes the Stirling Ultracold line of ultra-low temperature (ULT) freezers uniquely efficient, lightweight and flexible enough to meet today’s unprecedented COVID-19 vaccine cold chain deployment challenges.

ULT Reliability in the Broadest Range of Operating Conditions

• Widest temperature range: The ONLY commercially available ULT freezers that safely maintain temperatures from -86°C to -20°C and meet the cold storage efficacy requirements of most COVID-19 vaccine candidates, regardless of which are ultimately approved.
• Universal power and voltage: All our units plug into 110V outlets and can be used worldwide without modifications. They are even brownout-tolerant.
• Reliable Operation: Stirling Ultracold freezers operate in higher ambient room temperatures with minimal heat output.
• Connectivity: Building management system IOT connectivity available.

Breakthrough Portability and Flexibility for Remote and Clinical Uses

• Clinical: Portable and undercounter models bring -80°C vaccine storage to all points of patient care.
• Multipurpose: The -86°C to -20°C range is adaptable to more situations, including freezer backup.

Smallest Facility Footprint With Lowest Operating Cost

• Space: Store more vaccine and biospecimen inventory in less space within our compact footprint. The SU780XLE has the largest storage capacity per square foot/meter of floor space in its class.
• Energy: Our revolutionary Stirling engine uses less energy per sample capacity to help maintain lower energy costs. Our SU780XLE is ENERGY STAR® certified.
• Infrastructure: Significantly reduced power distribution/switchgear, backup power and HVAC system requirements.

Rapid Freezer Deployment

• Delivery: Product can be delivered quickly to help meet critical ULT storage needs.*
• Setup: Fastest and simplest installation without modifications to building power or HVAC.
