Product Description Guide:

Tank water Immersion Heaters, both flange type and screw plug models are a great choice for applications requiring larger wattages. These immersion heaters are designed for installation into a pipe body, tank or pressure vessel using standard pipe size. They are available in a wide selection of rates, sizes and sheath materials suitable for the heating requirements of water, air and other gases.These  flanged or screw plug type immersion heaters are very efficient since all energy that is generated is dissipated directly into the medium which is being heated. All flanged and screw plug heater models incorporate tubular heater construction, welded or brazed into a carbon steel pipe flange. Nema 1 terminal enclosures are supplied with all standard units. Moisture resistant (Nema 4) and explosion proof (Nem,a 7) models are also available. These industrial heaters can be fabricated with various sheath materials like Titanium, Incoloy, Stainless Steel, Steel, and Copper can be used as required for specific applications.

Standard Flanged Immersion Heaters have a 150 lb flanges but 300 lb and 600 lb flanges are also available. To guarantee sheath material and watt density compatibility with material or process being heated consult NPH. All flanged immersion heaters we offer you including heaters for hazardous locations are CSA/NRTL and UL approved.

High Conductivity Elements -
Filled with highest purity blends of magnesium oxide refractory (MgO) compacted to rock hard density to insure maximum thermal conductivity and maximum electrical resistance, and assure long element life.

Heavy Coil Construction -
Watt density on the heating coil is designed for low watt density operation by increasing the coil diameter and length to give maximum coil surface area and limit coil surface temperature, providing longer coil life.

National Plastic Heater Corrosion Policy:

NPH cannot warrant any electric immersion heater against failure by sheath corrosion if such failure is the result of operating conditions beyond the control of the heater manufacturer. It is the responsibility of the purchaser to make the ultimate choice of sheath material based on his knowledge of chemical composition of corrosive solution, character of materials entering the solution, and controls which he maintains on the process. * Not intended for use in hazardous locations.
