Commonly referred to as an inline heater, circulation heaters provide a clean and efficient means to heat flowing gases or liquids. They consist of an assembly of heating elements, pressure vessel (tank), terminal housing, mounting hardware, insulation and inlet/outlet connections. 

Choosing the right kind of boiler — whether for a new facility or a retrofit - is an important decision. Many plants and facilities rely on steam for applications like heating, cooking, hot water, sterilization and much more.

To achieve the best bang for your boiler or thermal fluid heater, the boiler or thermal heater must be properly designed for the given application. Look for the highest efficiency for the unit along with dependable operation and readily available service.

Measuring temperature across a process unit — for example, a furnace, desalter, hydrofiner, fixed-bed reactor or hydrocracker in refineries or similar process units in chemical plants — leads to improved process control, increased catalyst life, more efficient production, fewer process upsets and decreased emissions.

Integrated inside of the pressure vessel, the counter-flow device improves boiler efficiency without increasing the heat transfer surface area and flue gas pressure drop through the boiler.

Bete Fog Nozzle Inc., Greenfield, Mass., received ASME certifications for the design and manufacture of pressure vessels that meet ASME Boiler and Pressure Vessel Code Section VIII, Division 1.

An explosion that occurred December 7, 2009, at the NDK Crystal manufacturing company in Belvidere, Ill. resulted from corrosion in the walls of a pressure vessel that went uninspected for years.
