The Goetze KG product range is designed for hot water and heating systems as well as for cooling and air conditioning systems in single homes and multidwelling buildings and large building complexes. As an example, the safety valves for such installations are fitted with special sealing materials, which are suitable for glycol concentrations of up to 100%. A maximum degree of safety is of paramount importance when we develop new products.

Even for combined plants, so-called "Combined Heating and Cooling Systems", safety valves with the necessary approvals are available from our product range.
