Who We Are
Stirling Ultracold, a division of Global Cooling, Inc., is a developer and manufacturer of a new generation of environmentally friendly ultra-low temperature freezers which operate below -86°C. These freezers do not use dry ice, Peltier or conventional cascade refrigeration systems. Instead, the Stirling Ultracold product line operates on free-piston Stirling engine technology.

Marketed as Humm™ technology, the Stirling Ultracold product line offers significant benefits over conventional ultra-low freezers, including:
  • Reduced electric energy costs by as much as 50%
  • Reduced load on facility HVAC and back-power infrastructure
  • Longer operating life and reduced maintenance expectations compared to cascade refrigeration.
  • Tighter “straight-line” temperature control vs. on/off operating systems.
  • Better top-to-bottom temperature uniformity assured by an isothermal thermosiphon surrounding the freezer interior chamber.
  • Environmentally-friendly refrigerants, low refrigerant volume.
  • Significantly reduced noise level.
  • Lighter, smaller, quieter, including the Shuttle™, the industry’s first  portable
    -86°C ultra-low freezer.
  • Undercounter 3.6 cu.ft. and full-size upright storage models are launching in 2011.

The Stirling Swift™ control, alarm, monitoring and communications center serves as a touchscreen portal to ultra-low freezer operation, verification, performance, cabinet history and reserve cooling capacity.

Stirling Ultracold ultra-low freezers are available worldwide from leading distributors, dealers and manufacturers’ representatives who serve the life science, pharmaceutical, biomedical/clinical and biotechnology markets.

Global Cooling’s HUMM™ free-piston Stirling technology is based on the Stirling cycle which operates by cyclically expanding and compressing helium. Global Cooling’s HUMM™ technology is a free-piston machine driven by a linear driver that does not use any life limiting bearings and seals. It does not use oil. All moving components are supported by non-contact gas bearings.

The coolers can be used to cool by direct contact to the cold head or by transferring the heat using a thermosiphon.  Global Cooling has a broad patent portfolio with 14 issued and 4 provisional patents.

The Humm™ technology is deployed on the Stirling Ultracold product line, and is available by OEM arrangement to selected companies for use in allied applications.
