Second Nature, Medium-Temperature, CO2 Secondary Refrigeration System

SNMT2 medium-temperature systems use CO2 as the heat transfer fluid in a secondary coolant system. SNMT2 CO2 secondary refrigeration systems operate exactly like SNLT2 systems but at a temperature suitable for medium-temperature refrigeration. SNMT2 systems are a higher efficiency alternative to secondary systems using glycol.

Second Nature Medium-Temperature CO2 Secondary Refrigeration System

• CO2 is a “natural refrigerant” that is non-ozone-depleting (ODP=0) with almost no global warming potential (GWP=1).
• More efficient than conventional HFC systems in some climates.
• A less expensive alternative to HFC refrigerants.
• An excellent way to help achieve GreenChill Platinum-Level Certification.
• CO2 transcritical systems have proven themselves in thousands of installations throughout Europe.

Features & Benefits

  • Enhanced refrigerant management.
  • Reduces initial refrigerant charge by 60-90% as well as required oil charge.
  • Reduces refrigerant leakage rates due to refrigerant pipe reduction.
  • Significant reduction in costs associated with refrigerant leaks.
  • Avoid costly refrigerant retrofits that also impact sales floor activity.
  • Helps your store achieve GreenChill certification.
  • Simplified installation and maintenance.
  • Enhanced energy and performance.

Benefits of Using Second Nature CO2 Technology

  • CO2 is considered a natural refrigerant with very low global warming potential (GWP=1).
  • CO2 is an inexpensive refrigerant, compared with HFC, and is widely available.
  • In excess of 70 percent reduction in HFC refrigerant charge can be achieved. The entire primary refrigerant charge is confined to the machine room and condenser to enable simple leak detection and servicing.
  • The piping system utilizes a modified loop copper piping system – CO2 lines are typically one to two sizes smaller than traditional DX piping systems.
  • Excellent material compatibility – most equipment for commercial refrigeration can be used.
  • Medium-temperature system uses CO2 as a two-phase secondary coolant taking advantage of CO2’s high latent heat capacity – this dramatically lowers flow rates (typical 90% reduction) and pumping power compared to conventional secondary fluids (e.g. glycols).
  • System energy performance equivalent or better than conventional HFC systems.
