CO₂ Systems Technology

The rising demand of the international community for a green and safe environment has put pressure on the use of HFC refrigerants for HVAC&R applications. At the same time, the use of Carbon Dioxide (CO₂) as a refrigerant thrives and installations of CO₂ (R-744) refrigeration systems are increasing at a high rate around the world.

CO₂ is a natural refrigerant with zero ODP and a GWP of 1, being one of the best choices from an environmental perspective. CO₂ refrigeration cycles, require high operating pressures in order to operate efficiently. Several technologies that improve the efficiency of CO₂ systems have been established and are under development and optimization (e.g. ejectors, parallel compression, adiabatic cooling, etc.). New technologies lead to new and specialized design conditions that result in different levels of operating and design pressure and temperature.

TALOS^®S60

TALOS^®S60 tubes are specifically designed for a maximum allowable pressure of 60bar and feature a reinforced wall thickness in comparison with the standardized TALOS^®ACR tube range.

Combined with TALOS^®XS for 120/130bar and TALOS^®S80 for 80bar, TALOS^®S60 for 60bar completes Halcor’s copper tube portfolio for CO₂applications and provides the HVAC&R designer a full range of choices corresponding to the unique design conditions.

The well-known installation practices of refrigeration copper tubes apply both in systems and in the field (see relevant EN378 standard for guidelines).

TALOS^®S60 Features

• Suitable for systems with a design pressure up to 60bar
• Traditional processing techniques and equipment
• Excellent “cold formability”
• Smooth internal surface enhancing flow rate
• High purity of internal surface
• Stable mechanical properties covering an extensive temperature range
• Excellent brazing ability
• Compatible with standardized ACR fittings
