History and innovation
Stirling Ultracold was founded with bold ideas. It is to reinvent the way Ultra-low temperatures are achieved using advanced and energy-efficient technologies. Rather than relying on traditional cascade compressor systems that dominate the ULT freezer market, the company has introduced an alternative, a free piston sterling engine.
Originally developed for aerospace and advanced scientific applications, this cutting-edge engine was adapted for commercial refrigeration by Sterling Ultra Cold. Its adoption marked a turning point in the ULT freezer design, allowing for dramatic reductions in energy usage, heat output, noise and environmental impact.
Sustainability Leadership
Sustainability is not just a feature of Sterling Ultra Cold products, but a fundamental pillar of the company’s philosophy. As climate change and energy saving become a central concern for science-driven industries, Sterling Ultra Cold is at the forefront of sustainable cold storage innovation.
Product Portfolio
Stirling Ultracold offers ultra-low temperature freezers in a variety of ranges. Each is tailored to different space and storage needs.
ult25neu:
ult25neu is the only truly portable ultra-low temperature (ULT) freezer available today to provide cold chain samples and biological products to teleclinic patients. It provides secure and reliable ULT freezer storage in the field and provides the GO SU105UE Undercounter/Stackable Freezer.
This stackable model uses innovative free piston Stirling engine technology to provide a reliable, compact ULT storage solution, with no few moving parts, oil or compressors. The SU105UE’s front access design allows for convenient space savings for benchtops, undercounters, or double stacks, providing amazing storage capacity with a small footprint. vault100 upright model:
The first ULT freezer with a temperature range of -100 to -20°C has the highest temperature uniformity and compliance with market setpoints. The Vault100 offers a large user interface display with onboard predictive analytics and freezer diagnostics, a more robust free piston Stirling engine design, and a 360-degree approach to sustainability.
Stirling Ultracold also offers additional racking solutions and the Senseany Where system, a cloud-based tool that allows users to remotely monitor and monitor and audit the secure storage of valuable biological specimens from anywhere in the world with just an internet connection.
