Whenever the resistance of copper is not enough, nickel as brazing material is chosen. The units of the GNS-Series offer all the advantages of a brazed plate heat exchanger, but they are essentially more stable against corrosive media such as ammonia, deionised water, sulphides and sulphates. But not every nickel-brazing is the same: only around 75% is made of pure nickel, the remaining 25% is our secret – and your benefit. Also units of the GNS-series have the proven technical features like Safety ChamberTM, Delta InjectionTM and Full Flow SystemTM available. Thus, the products of the GNS-Series serve with its wide range of applications up to 200°C/392°F and 16 bar/232 psi the demands of the market.
