Candovent process ventilation reduces costs and enhances safety

Etching plants use extremely strong acids that corrode material from the surface of components. As a result, occupational safety and environmental protection must be prioritised when using these chemicals.

Candovent process ventilation is an innovation that has been developed by Galvatek to effectively extract vapours from chemical tanks. It eliminates the need for plant operators to wear special safety gear and prevents damage to the plant structure and ventilation system from corrosive vapours. The tanks are made from either stainless steel or special plastics, depending on the customer’s preferences. Samples can also be taken from the baths safely from external sampling points.

Candovent process ventilation saves not only the environment but also money. Depending on the climate, the air entering the plant has to be either cooled or heated. Candovent process ventilation can reduce heating/cooling costs by up to 90 percent compared to traditional ventilation systems. Candovent process ventilation also uses up to 20 times less air than traditional plant ventilation systems.
