High pressure tubes (K65 & TALOS XS)

Growing concerns about the environmental impact of hydrofluorocarbon (HFC) refrigerants and tougher environmental regulations have led to a re-emergence of carbon dioxide (CO₂) refrigeration systems. CO₂ Refrigerant (R-744) is used as a working fluid in many climate control systems, in applications such as commercial refrigeration, hot water pumps, vending machines, etc. The supermarket industry in particular is implementing an ecological and efficient retail concept by successfully embracing advanced CO₂ refrigeration technologies developed by manufacturers of cooling systems.

However, due to the physical properties, cooling systems based on CO₂ require a much higher pressure compared to conventional systems. The design pressure of such systems can be 120/130 bar in the trans critical cycle. CO₂ meets the demand for low global warming potential (GWP) refrigerant, but presents challenges in both application and handling. The higher operating pressures and large temperature variations require that all system components, including tubes, are designed accordingly.
