Pascal Air
Air to Air, Pure and Simple

Pascal Air is a refrigeration system that creates ultra-low temperature (-58℉~-148℉) by using an air cycle. It uses the air as its refrigerant; therefore there is absolutely no environmental impact. In the ultra-low temperature (-58℉~-148℉), it can save 50% of energy and CO2 emission when compared with systems that use chemical refrigerants.

  • Air is ultrimate refrigerant gas. Zero ODP (Ozone Depletion Potential) and Zero GWP (Global Warming Potential)
  • 50% energy saving compared to HFC23/HCFC22 refrigeration system (under -76℉ room temperature)
  • For cold storage use, plant building cost is very low due to direct use of air in the storage room.
  • Simple construction due to the all-in-one turbo type compressor-expander = Lower maintenance cost
  • Highly efficient because the expander generates the power to drive the compressor.
