THE APPLICATIONS OF CIRCULATION HEATERS

Flanged immersion heaters are the most efficacious and cost effective industrial heating devices that are flexible, easy to operate and require minimal maintenance.

Circulation heaters are a popular type of immersion heaters that are typically used in preheating, regulating and maintaining temperatures of gases and fluids that are a part of large-scale military, commercial and industrial processes. There are various installation or configuration types for circulation heaters that include closed loop installations with indirect heating or direct heating and open heating configuration.

Importance in Oil Industry

In oil industries, immersion heaters are used to provide the right amount of heat to oil which makes it easy to flow through pipes. Once installed to the oil tank or the container, the tank heater (Immersion heaters) are undetachable however you can remove different parts from the device for repair and maintenance. These are especially designed with a powerful body with superior technological modifications that makes them sturdy enough to withstand extreme weather and environment along with being long lasting than many other similar contraptions. Another benefit of oil heaters is their smaller size which makes it easier to install them acquiring fewer space. “Pocket tube” which is the actual controlling device is attached to the heater in a way that when these get immersed in the tank, the control box will be located on the exterior wall away from the product for safety. This has proved to be beneficial in case anything went wrong with the heater or the controller, you do not need to empty the entire tank.

Another common feature of these oil immersion heaters is the surface load which is always kept at a constant temperature without any alteration in order to keep the oil from rotting up. If you will not be careful of this, a carbon layer will develop on the interior walls and surface of the device which will disrupt the heat transfer procedure.

How to Select the Right Circulation Heater

One of the proper ways to select the circulation heater is to check the sheath material, watt density and temperature control mechanism. Given below are a few guidelines which will definitely help you to choose the right type of heater.

· Always ask the manufacturer and supplier about the heating element which have to be according to the heating medium. In case of oil for pipeline industries, strong heating material is required which can withstand high temperature without corroding the product and heater itself.

· If possible, have a test run before buying but remember not to exceed the actual temperature or watt density.

· Latest technology includes the temperature control mechanism built outside the actual heater so you can easily monitor and manage the process away from the device. This has proved beneficial for health and safety.

· The terminal enclosure must be well adjusted and of the right size to cover the wiring and control mechanism from damage.

· For large storage tanks, it is recommended to apply large size or multiple heaters to provide the exact temperature keeping the oil viscous enough to flow easily through pipes.
