Electric Flow Heaters

Short Description:

Flow Heaters and Process Heaters for process plants in the oil and chemical industries. Our WNH flow heaters are used in a.o. the oil industry and in the petrol chemical industry for heating of fluids and gasses in connection with the actual process in each specific industry.

WNH flow heaters are used for heating liquids and gases. They are manufactured to customer specifications in explosion-protected design  (ATEX, IECEx, etc.) or in high-quality industrial design.
