The fittings "SANHA® RefHP®" (series 29000) comprise high-pressure solder fittings for copper-iron pipes for use in high-pressure installations such as CO2 cooling systems.

The fittings are made of copper-iron (CuFe2P, CW107C) and meet all quality requirements of the German "VdTÜV material sheet 567" as well as the AD 2000 data sheet W 6/2 and comply with various other certifications such as UL.

In air-conditioning and cooling technology, especially in commercial or industrial cooling systems, environmentally friendly solutions are becoming more and more important. Optimal results are expected above all by an increase in efficiency and the use of ecologically (less) harmless refrigerants such as CO2 (R744). These refrigerants are used primarily in the transcritical range with higher operating pressures. Therefore, the use of CO2 leads to higher operating pressures of up to 130 bar in some cases - and at these pressures there is a correspondingly high risk to employees' safety as well as the continuous function of the piping system and the environment.
