Screw Plug Immersion Heaters

Screw plug immersion heaters are used by the process heat industry for a wide range of applications. This type features a broad selection of screw plug sizes, wattage, materials and junction box types. Screw plug heaters may be threaded directly into a sufficient tank wall or used with a companion coupling.

Installation Recommendations

• Select the heater size best suited for your application.
• Choose the appropriate watt density for the solution.
• Choose the proper sheath for the solution being heated to avoid corrosion.
• Uniform heat distribution in larger tanks is enhanced by the use of several heaters rather than one large heater.
• Protect heaters and tank against liquid level drops with safety controls.
• Clean heaters periodically to avoid premature failure.
• Avoid physical damage to heaters.
• Mount all heaters securely.
• Use the appropriate terminal box for each application.
• Select an appropriate temperature control.
• Electrical wiring should be in accordance with national and local codes.
• Contact us for any sales or service questions or problems.
