CO2 Trans-critical Booster System for Display Case Refrigeration

The Advansor CO2 Display Case Refrigeration Systems is an HFC-free refrigeration alternative that utilizes carbon dioxide as the only refrigerant in the system. Supermarkets, grocery stores, small format and large format food retailers can take advantage of the inherent benefits of CO2 and combine them with those of other Second Nature systems – reducing direct refrigerant emissions to the lowest level possible.


  • Air-cooled gas cooler with variable-speed fans.
  • Electronic-controlled, high-pressure control valve and flash gas bypass valve ensure optimal performance at all ambient conditions.
  • Simple electronic oil management system ensures adequate lubrication and long compressor life.
  • A suction accumulator and heat exchanger protect low-temperature system from liquid flood-back.


  • Specially-designed evaporator coils for CO2 direct expansion operation provide good oil return back to the system.
  • Electronic expansion valves on all evaporators ensure efficient coil operation.



  • It’s an HFC-free system – CO2 is the only refrigerant used.

  • CO2 is a “natural refrigerant” that is non-ozone-depleting (ODP=0) with almost no global warming potential (GWP=1).

  • The system’s higher quality heat reclaim opportunities improve store energy performance.

  • Advansor systems require a lower CO2 charge and have a smaller weight and footprint compared to COsecondary systems

  • More efficient than conventional HFC systems in some climates.

  • An excellent way to help achieve GreenChill Platinum-Level Certification.


We recently worked on a project in Sparta New Jersey for a ShopRite using this technology. The refrigerated cases are as ascetically appealing as they are environmentally friendly; there is no having to choose between the two.
