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 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 ultralow freezers.
• Reduced electric energy costs by as much as 60%
• 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. cyclical on/off cascade operating systems.
• Better top-to-bottom temperature uniformity assured by an isothermal thermosiphon surrounding the freezer interior chamber.
• Environmentally-friendly refrigerants, lower refrigerant volume.
• Significantly reduced noise level.
• Lighter, smaller, quieter, including the Shuttle™, the industry’s first portable -86°C ultralow freezer, www.stirlingshuttle.com
• Undercounter 3.6 cu.ft. and full-size upright storage models are launching in 2011.
