Tank Heaters – Tank Heating Coils

Heating Coils and Tank Heaters are installed in tanks to heat the stored fluid or to maintain its temperature to a defined level. They are widely used in fluid storage tanks, in chemical and process plants, oil refineries and petrochemical industries. The heating utility fluid most commonly used is steam, but hot water or hot oil can also be used. Thermal convection enhanced by the coils, keeps tank contents in motion, increasing time between cleanings. Due to low skin temperature and high thermal convection velocity, surfaces remain scale and dirt free for long periods, thus maintaining heat capacity and reducing operating cost for the customer.

Our heating coils can be supplied in two arrangements:

- Horizontal coils are particularly recommended for floating roof tanks or when low liquid levels have to be heated. The fins welded on to horizontal coils are of the perforated type, to ensure a better drainage from the fin channels and keep the heating surface clean, which means higher heat transfer efficiency.

- Vertical coils avoid heating through insulating layers of sediments, which would reduce heat transfer efficiency.

Technical Product Sheet:

Upon request and depending on fluids to be heated, other materials, such as stainless steel (AISI 304-316-321), can be used.
