We’re excited to share an update to our ULT25NEU portable ultra-low temperature freezer—now available in two package options: ECO and PRO.
Designed to safeguard temperature-sensitive materials wherever they’re needed, the ULT25NEU delivers reliable ultra-low temperature performance in a compact, portable design. With this new package structure, customers now have the flexibility to choose the level of protection, documentation, and warranty support that best fits their application.
The ECO package offers essential ultra-low temperature performance, making it an excellent option for point-of-use or short-term cold storage, users who do not require GxP calibration documentation, and applications where redundant cold storage is readily available.
For users working in more regulated or mission-critical environments, the PRO package adds enhanced peace of mind with an extended (3 year) warranty, Stirling UltraGuard, and a Certificate of Calibration & Conformance—supporting compliance, traceability, and long-term confidence in performance.
No matter which package you choose, both options deliver the same trusted ULT25NEU performance, including a wide temperature range, flexible AC and DC power input, and sustainable operation using 100% natural refrigerants.
With ECO and PRO, you’re not choosing between performance—you’re choosing the level of protection and support that makes the most sense for your operation.
About Stirling Ultracold and Global Cooling: Global Cooling, Inc. manufactures and sells Stirling Ultracold freezers, a new generation of environmentally friendly ultra-low storage solutions which operate between -20°C and -86°C. These freezers do not use compressor-based or cascade refrigeration systems. They use patented free-piston Stirling engine technology that was originally developed for energy, aerospace and industrial applications before successful commercial application in ultra-low temperature cooling systems.
