The SANHA group is one of the leading European manufacturers of pipe systems for drinking water, gas, solar, heating, cooling and sanitary applications for use in domestic and industrial settings. The company has approximately 8,300 items in our product ranges, covering most commonly used materials such as copper, copper alloys, stainless and carbon steel as well as its innovative silicon bronze lead-free fittings for use in drinking water applications.

In air conditioning and refrigeration technology, particularly in commercial and industrial refrigeration systems, environmentally friendly solutions are becoming more and more important. Optimum results can be obtained by an increase in efficiency and the use of ecologically safe refrigerants such as CO₂ (R744), which are mainly used in the transcritical part with higher operating pressures. However, the use of CO₂ leads to higher operating pressures potentially up to 130 bar, and SANHA RefHP fittings are ideally suited for high operating pressure.
