The fittings of the "SANHA RefHP" brand (Series 29000) include high-pressure solder fittings for copper-iron alloy pipes for use in cooling systems. These solder fittings are made of copper-iron (CuFe2P, CW107C). SANHA has been actively offering this series for several years for high-pressure systems that are operated with CO2 as a cooling medium, for example. The operating pressure extends up to 130 bar and the operating temperature from -196 to 150 degrees Celsius.

In air conditioning and refrigeration technology, especially in commercial or industrial cooling systems, environmentally friendly solutions are becoming more and more important. Increased efficiency and the use of more sustainable refrigerants such as CO2 (R744) are expected to lead to higher overall efficiency. These refrigerants are used primarily in the transcritical range and with higher operating pressures. Especially with larger dimensions such as 2 1/8” the demand is growing. This also applies to the dimension 2 5/8", which is used in industrial plants and large refrigeration piping. SANHA now also offers this dimension and thus covers the entire range of CuFe solder fittings for high-pressure applications.

The RefHP series solder fittings offer a number of advantages over classic welded connections with stainless steel or brass. For example, brazing is about two and a half times faster than TIG welding. In addition to the time savings, lower labour costs and less training for welding specialists speak for the use of RefHP copper-iron fittings. The series can be combined with all common tubes made of the same material.
