The innovative Stirling Ultracold ultra-low temperature freezers utilize a free-piston Stirling engine to achieve highly efficient storage of general laboratory materials ranging from -20°C to -86°C. Conventional ultracold freezers employ a compressor system that is highly susceptible to wear and tear and has a short useful life. The Stirling ultra-low temperature 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 its successful commercial application in ultra-low-temperature cooling systems.

Product features of SU105UE ultra-low freezer:

  • Low-wear free-piston Stirling motor with 7-year warranty
  • Freely adjustable storage temperature from -20°C to -86°C
  • Unrivaled temperature stability for maximum sample safety
  • Ultralow energy consumption for ultralow heat dissipation
  • Lowest maintenance costs - no cleaning of filter mats and regular defrosting necessary
  • 100% natural refrigerant and no use of oil
  • Sustainable production and packaging
  • Very quiet-running and efficient cooling, even at ambient temperatures of up to +35°C
