What Are Heater Control Panels

Heater control panel maintains the overall performance of the industrial immersion heaters. It is actually a control box attached to the device or a closed room that houses the entire mechanism and maintains stability and performance of the heater. Besides this, the tool ensures that the heat distributes evenly to the content within the tank or vessel, along with preventing the process of overheating and deterioration of the fluid.

For maximum efficiency and performance of the heater itself, control panel heaters are also assembled as per the customer demand and its possible application. The terminal boxes of the control panels come in a host of different variations, in regards to the type of heater and considering the use of the device.  

Control Box Types and Uses

The design of a control panel’s terminal box esures that it is waterproof, moisture resistant, anti-explosive and dustproof.


It is actually the name of a specific terminal box with reference to its performance and application. This particular type is suitable for standard/non-hazardous operations like the heating process that takes place within an industry or a factory.


This design uses robust technology and is most common in outdoor processes. It has a weather-resistant enclosure is which protects the device against moisture, humidity and other extreme environmental effects.        

Design and Specification

Digital heater control panels are installed on to the gadget to examine and administer the temperature of the fluid. The typical set design includes internal wiring, switches and various fuses along with heat sensing mechanism like thermocouples, as well as RTD.

A standard control panel is ideal for heaters with a maximum watt density of 30 to 200 amperes. However, upon request, Wattco can custom-design a controller for heaters that range above 200 amperes.  

Technical Insight

There are various types of control panels available in the market today that function with heaters having 4000 amperes watt density, which is approximately 600 Volts. Moreover, automated remote mounted controls are also obtainable on request. While purchasing the package, you will get;

  • Contactor power switching unit
  • A complete design drawing so as to make you familiar with the parts and technical
  • Additional/replacement parts
  • Operating and component manual


There are basically four types of control panels. Check out below where each is applicable.

  • Basic control is for heaters that use a thermostat, limit controlling mechanism, timers and additional components.
  • Advance control is best for various heater types both within an industry and outside. Suitable with various electrical installations.
  • Contactor stages are for multi-stage heaters that serve to heat various types of content like water, oil, chemical, gas or any other.
  • Base Load SCR is for contactor stages as a step-controlling device. Another name for it is a solid-state power control.

  Additional Features and Benefits

A heater control panel provides many benefits if you have it installed on to your heating device. Have a look below to know about its additional features and all the benefits you would acquire in case of installation.

  • It is reliable, cost-effective and is a ready-to-connect tool to maximize the heater performance.
  • Automated remote controlling feature allows you to manage the entire process without any hassle.
  • Added alarm informs you of any threat related to overheating or any other technical fault that arises.
