Corrosion protection

Water, depending on its origin and pre-treatment, can be very aggressive: it attacks metallic materials, causes the formation of rust, pitting and other destructive forms of corrosion. Such effects must be prevented at all costs in order to ensure the function or long working life of expensive equipment.

Heating and cooling systems often are mixed installations consisting of different materials, such as steel, brass, copper, aluminium or galvanised surfaces. Such mixed installations are problematic from a corrosion point of view, because corrosion potentials can occur between base metals and precious metals.

In such cases, special chemical inhibitors must be used to ensure that soft metals in particular, such as copper and brass, are protected against attack by aggressive water, in order reliably to prevent severe corrosion to other system components.
