TALOS® XS

Green Refrigeration

The increasing concern of the environmental impact of hydrofluorocarbon (HFC) refrigerants, as well as the more stringent environmental regulations, have prompted a re-emergence of carbon dioxide (CO2) based refrigeration systems. CO2 refrigerant 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, implemented an ecological and efficient store concept by successfully embracing advanced CO2 refrigeration technologies developed by refrigeration system manufacturers.
 

 

 

CO2 as a refrigerant

CO2 (R-744) refrigerant is termed a “natural” refrigerant because it exists in the natural environment. Released from refrigeration systems into the atmosphere, CO2 has a negligible effect to global warming and thus is not under any regulatory restrictions, as is the case for CFC, HCFC and HFC refrigerants.
 
In addition to its environmental-friendly character, CO2 is currently viewed as a viable solution for low-temperature refrigeration applications because it is non-ozone depleting, non-toxic, non-flammable and has a high volumetric cooling capacity. However due to its physical properties, CO2 based refrigeration systems request much higher pressure, compared to conventional systems. The design pressure of such systems can be 120/130bar in the trans-critical cycle. CO2 meets the demand for a low-global warming potential (GWP) refrigerant, but presents challenges in both its application and handling. The higher operating pressure and broad temperature fluctuations require that all the system components, including piping, should be designed accordingly.
 

Extra-Strong TALOS® XS tubes for high-pressure systems

TALOS XS tubes are manufactured using a high strength copper-alloy (CuFe2P) material, in order to satisfy the demands of today’s high-pressure CO2 systems in refrigeration, as well as, other high-pressure HVAC&R applications. TALOS XS tubes are designed to withstand high operating pressures of up to 120/130bar. At the same time, TALOS XS tubes are manufactured with comparatively thinner walls and thus achieve an economical advantage that meets the pressure equipment design. The well-known installation practices of refrigeration copper tubes are followed also for the case of TALOS XS tubes, both in systems and in the field (see relative EN378 standard for guidelines). Since the processing methodology remains essentially the same, existing tooling and handling equipment are utilized. This includes brazing with standardized silver braze alloy (min. silver content of 2%), bending with traditional tools and joining with standardized fittings made from copper alloy (CuFe2P).
