Control panels are used to maintain the heating system’s stability and heat transfer efficiency to prevent issues such as overheating and chemical disintegrations of a fluid. To provide the precise safety mechanism of the heating system, control panels can also be entirely customized to meet most of the requirements of the target application.
Various terminal boxes are available depending on the protection required- moisture-proof, explosion-proof, waterproof, and dustproof. A NEMA 1 standard terminal box is normally suitable for non-hazardous area operations.
NEMA 4 terminal boxes (weather-resistant enclosures) are commonly used for outdoor operation, which requires protection against moisture and humidity. Digital temperature controllers are installed to monitor the ambient and set-point temperature. A typical control panel set possesses of switching and fusing devices, including internal wirings.
Along with the temperature sensor tools such as RTD and thermocouples, Wattco’s control panels will ensure maximum heat generation safety for various voltage ranges. The support and safety documentation (with schematics support, drawings, and bills of material) would ensure the control panels will be installed and operated perfectly as designed. Industrial control panels regulate temperature and provide safety mechanisms to prevent overheating your liquid and protect your heating elements.
Control panels come in many different terminal boxes – standard NEMA 1 terminal boxes, dust proof boxes, waterproof boxes and explosion-proof boxes for hazardous areas. Digital controllers are used to display ambient and target temperatures of your solution. They contain contactors, relays, fuses, on–off disconnect switches, and other components to help regulate your Wattco™ heater in a safe environment. In conjunction with thermocouples or RTD sensors, temperature controllers are the “brains” of the system and determine the heat intensity of your heaters.
Heating control panels are typically available for heaters generating at least 30 Amps to over 200 Amperes. Special accommodations can be made for systems that are over 200 Amperes. NEMA 4 terminal boxes are typically used for outdoor applications where concerns of moisture and humidity is a factor. Flow switches can also be used for circulation heaters. All Wattco™ control panels come with circuit schematics and support documentation that might be required for configuration purposes.
