COPPER

TALOS® XS

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.

CO₂ as a refrigerant

CO₂ (R-744) stands out as one of the most environmentally friendly refrigerants available today. As a naturally occurring substance, it boasts zero ozone depletion potential (ODP) and an ultra-low global warming potential (GWP) of just 1—dramatically lower than synthetic refrigerants. It is non-toxic, non-flammable, and free of harmful PFAS chemicals, making it a safe and sustainable option for refrigeration and heat pump systems.
However, due to its physical properties, CO₂-based applications require special consideration during design stage, as they operate at significantly higher pressures than conventional systems.
The design pressure of such systems can be either 120/130bar in the trans-critical or 80bar in the sub-critical applications. 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 designed to withstand high operating pressures of up to 130bar.
At the same time, TALOS® XS tubes are manufactured with comparatively thinner walls and thus achieve an economic 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).
