Circulation heater

Circulation heaters are efficient electric heating systems that require minimal time and labor to install. They combine heating elements, vessel, insulation, terminal enclosure, mounting brackets, and inlet/outlet connections into a complete assembly. These heaters are designed to heat forced-circulation air, gases, or liquids, making them suitable for in-line or side-arm operations.

Circulation Heater Typical Application

Inline Heating

Inline Heating:

Circulation heaters installed directly in the fluid line eliminate the need for storage tanks, reducing heat losses and meeting constant demands for heated water or oil.

Side arm Circulation Heater

Side Arm:

Multiple circulation heaters can fulfill the requirements of large storage tanks, offering temperature control flexibility and reducing power demand.

Closed-Loop Fuel Oil Heating:

Several individually adjustable circulation units meet temperature and fluid flow requirements, effectively reducing electrical demand on utility bi

How to select a circulation heater

1. Selecting the right components for a circulation heater is crucial and requires careful engineering judgment and evaluation of the application. After determining the heat requirement, it is essential to select the appropriate flange and vessel material, heating element sheath material, and watt density to ensure the longevity of the heater. The final equipment selection relies on the process knowledge and engineering expertise of the designer or plant engineer.
2. You need to consider the following factors when the application a) The properties of the heated medium, include viscosity, specific heat, density, and corrosiveness. b) The presence of contaminants in the medium. c) The corrosion resistance of the heater sheath material. d) The watt density of the heating elements is determined by the watts per square inch and the flow rate of the heated medium. e) The vessel design and material, considering the pressure and temperature of the fluid being heated.

3. Right to Understand. The selection of the sheath material is determined by the buyer’s understanding of the corrosive solution’s chemical composition, the characteristics of materials introduced into the solution, and the implemented controls to maintain the process. This knowledge guides the ultimate choice of sheath material to mitigate corrosion.
