Screw plug immersion heaters utilize an NPT screw plug for direct immersion into liquids, oils, or other heat transfer mediums. These heaters utilize a rugged tubular heating element with sheath materials of copper, stainless steel, or Incoloy. The elements are formed and welded or brazed into the screw plug fitting for a liquid tight seal.
These heaters are available in 1-phase or 3-phase designs. The standard terminal enclosures are NEMA 1 for general purpose applications. Other terminal enclosures such as NEMA 4 for moisture resistance or NEMA 7 for explosion resistance are available.
In addition, these heaters can be provided with integral thermowells for thermostats or electronic temperature controls .
