Product DescriptionScrew Plug Immersion heaterScrew Plug Immersion Heaters are screwed directly through a threaded opening in a tank wall or through a matching pipe coupling or half coupling. Sizes of screw plug heaters are available with 1", 1-1/4", 1-1/2", 2", 2-1/2" pipe threads. A wide selection of screw plug sizes, kilowatt ratings, voltages, sheath materials, terminal enclosures and thermostats makes these compact heaters ideal for all types of applications.SpecificationApplicationsScrew Plug Immersion Heaters are used for heating liquids in a variety of processes. These heaters are ideal for process water heating and freeze protection. All types of liquid heat transfer solutions can also be heated using these compact, easily controlled units. The direct immersion method is energy efficient and well suited for many applications.? Hot Water Storage Tanks? Warming Equipment ? Preheating all Grades of Oil? Food Processing Equipment? Cleaning and Rinsing Tanks? Heat Transfer Systems? Process Air Equipment? Boiler Equipment? Freeze Protection of Any FluidThe goal is to optimize the heater configuration to ensure the longest life possible, while minimizing overall product and life cycle costs. The general temperature, sheath material and watt density guidelines below can aid in proper heater selection for some common liquids. Contact us for further assistance.LiquidMax.
