The CO₂ refrigerant (R-744) it is called a "natural" refrigerant, because it exists in the natural environment. Losses from cooling systems to the atmosphere have a negligible effect on global warming, so CO₂ has no regulatory obligations in the European Union, as in the case of CFCs, HCFC and HFC refrigerants. In addition to its environmentally friendly nature, CO₂ is now considered a viable solution for low temperature cooling 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 require a higher pressure compared to conventional systems. The design pressure of these systems can be 120/130bar in the supercritical phase.

CO₂ meets the demand for low GWP (Global Warming Potential), but presents challenges both in implementation and handling. The higher operating pressure and wide temperature range require that all parts of a system, including piping, they should be properly designed.

The TALOS tubes^ⓇXS are manufactured from a special high resistance copper alloy (CuFe2P) to meet the demands of today's high pressure CO₂ cooling systems, as well as other high pressure applications in the HVAC industry&R (Heating, Ventilation, Air-Conditioning & Refrigeration). The TALOS tubes^ⓇXS are designed to withstand operating pressures up to 120/130bar. At the same time, the TALOS tubes^ⓇXS are manufactured with comparatively thinner walls, thus achieving an economic advantage that meets the design criteria of the equipment. Standard copper refrigerant pipe installation practices are followed for the installation of TALOS pipes^ⓇXS (see also the guidelines according to EN378). Since the processing methodology remains essentially the same, the existing tools and the handling of the equipment is done by the user easily and quickly, such as bending with power hand tools, the welding of the pipes with a standardized copper-silver alloy (minimal silver content 2%) and joining them with standardized copper-iron alloy fittings (CuFe2P).
