Case study No. 10:
KVS system in galvanics

Initial situation

Contaminated air is a big issue to in electroplating. It can prevented by discharging the surface evaporation of the electroplating tanks. The aggressive components are removed from the workplace air, merged and later cleaned in the scrubber.

At the same time, fresh air is blown into production from the outside. This must be preheated, especially in winter. In the exhaust air of the electroplating is energy that is lost.

Through a closed-loop composite system, this energy can be used to preheat the fresh air.


By merging the exhaust air of the different basins, the exhaust air in your chemical composition is not clearly definable. After the scrubber, this is mostly neutralized, but there may still be some particles in the air that attack a stainless steel exchanger.

Coated heat exchangers are also no alternative, as the coating is the only protection against corrosion and and with the slightest injury the exchanger is no longer corrosion resistant.. What is needed is a fully corrosion-resistant heat exchanger that can withstand attacks from various chemicals and at the same time has good heat transfer properties.


The Calorplast Gas Liquid Heat Exchanger made of solid plastic for cooling/heating aggressive gas flows consists of series-produced, interchangeable modules with smooth tubes.

All parts are made of high-performance modules and are connected to each other without seal in the welding process. The optimized tube arrangement guarantees maximum performance.


The KVS system can be operated for many years with low maintenance and trouble-free operation. In addition to the lower the contaminated air, the operator can save money through the heat recovery system and at the same time reduce the CO2 emissions of the entire plant.
