Stricter requirements of the amended F-Gas Regulation have been in force since the beginning of 2025. As a result, manufacturers of refrigeration and air conditioning appliances are actively redesigning their product portfolios in order to place environmentally friendly appliances on the market that meet the applicable requirements.

The solutions chosen by the major manufacturers can vary greatly. Some have opted to switch to refrigerants such as propane (R290 – GWP 3), propene (R1270 – GWP 2) or isobutane (R600a – GWP 3). These refrigerants are very environmentally friendly and belong to safety group A3, which means that they are highly flammable. This makes handling the corresponding systems much more complex in terms of design, installation and maintenance, and there are many regulations and safety aspects to consider.

The refrigerant CO2 (R744) is in safety group A1, i.e. it is non-flammable and non-toxic. Nevertheless, handling carbon dioxide requires sensitivity, as it has a suffocating effect depending on the concentration and cannot be detected by smell, color or taste.

In systems operated with CO2, significantly higher pressures are used than in conventional refrigeration and air conditioning units, which is why the RSG CO2 valves have been specially designed for this application and extensively tested in their systems in cooperation with pilot customers.

This realistic test environment has helped us to develop a very special valve for this young potential market that will inspire you with its amazing features:

  • Compact design that can be used in the smallest of installation spaces
Masse CO2 Ventil » %sitename -% » 2025
  • Economical due to small size and operation up to 130 bar with only 8VA (AC) / 6W (DC)
  • Optimized price/performance ratio
  • High-quality materials such as stainless steel and high-performance sealing materials guarantee durability over time and a long service life of millions of switching cycles
  • Can be used in a wide temperature range from -40°C to 150°C
  • With reliability, great safety and high precision thanks to elaborate tests that take into account pressure, temperature and chemical resistance requirements
  • High flexibility thanks to our modular system, which allows valves to be configured for specific applications. Seals, connection options and voltages can be selected to meet specific operating requirements
