Immersion Heaters

Typical Applications:
Glenn immersion heaters provide the best known means of heating such liquids as water, oil, alkalies, chemical solutions, certain acids, anti-freeze, electroplating colutions, and salt solutions. There are very few limitations to the use of the Glenn immersion heaters. They can be used with equal effectiveness in open containers or in closed vessels under pressure, and will provide constant well-regulated temperatures when used in conjunction with positive thermostatic temperarure controls and magnetic contractors for very heavy heater loads.

  • Type SPO-2 has two steel sheathed hairpin elements mounted on a standard 2" steel screw plug heater. Units are for general use in circulating oil immersion service. When heating non-circulating or heavy and viscous materials, lower watt densities are required.
  • Type SPS-2 has two stainless steel elements mounted on a standard stainless steel screw plug. Unit is designed for use in corrosice water solutions or solutions that are corrosive to steel but not viscous or highly acid.
• SP-3 Three Element Immersion Heater
  • Type SPC-3 has three copper sheathed hairpin elements mounted on a standard 2-1/2" brass screw plug header. Units are primarily used for water heating. They may be wired in single or three phase.
  • Type SPO-3 has three steel sheathed hairpin elements mounted on a standard 2-1/2" steel screw plug header. Units are for general use in circulating iol immersion service. When heating non-circulating or heavy and viscous naterials, lower watt densities are required.
  • Type SPS-3 has three stainless steel sheathed hairpin elements mounted on a standard 2-1/2" stainless steel screw plug header. Units are designed for corrosice water solutions or solutions that are corrosive to steel but not viscous or highly acid.
• DC And DO With Integral Thermostat
  • Type CD units are used for water immersion service. They are constructed with copper sheath elements silver soldered to brass screw plug headers. These units contain contain an integrally mounted thermostat having a temperature range of 60 deg. F to 250 deg. F. An over-temperature manual reset cutout is available.
  • Type DO units are for oil immersion service. Element construction is steel. The integral thermostat is adjustable from 60 deg. F to 250 deg. F. A 200 deg. F to 550 deg. F thermostat can be specified.
• Type DMA Dishwasher Heater Standard Screwplug
  • Type DMA units contain stainless steel sheathed tubular elements mounted on 2" brass screw plug heater. Integral thermostat provides automatic temperature control with the additional feature of low-water cut-out protection (manual reset type). The thermostat is externally adjustable in the range of 60 deg. - 250 deg. F.
  • Direct placement of the sensing bulb on the top element leg provides closer differential and faster low-water cut-out response than previous designs where sensing bulb is located in a thermowell. A unique sealing gland eliminates the need for a thermowell and yet provides a simple method for field replacement of thermostat.
  • Unit may be mounted in thin wall tanks by using Lock-Nut Assembly #10-1300
  • These units are used in wash and rinse compartments of commerical dishwashers and other sterilizing water heating applications where low-water cot-out protection is desirable.
• Urn Immersion Heaters
  • Type GSU Urn Heaters are designed for long life and dependable service. Glenn GSU urn heaters are applicable for coffee urns, percolators, steam tables, kettles, sterilizers, and humidifiers. Easy installation is accomplished by direct mounting through a 2-7/16" diameter hole in the bottom of the tank. Tightening the simlified peripheral type clamp assembly to a gasket and pressure ring provides a water tight seal. Glenn GSU urn units are supplied with a rugged terminal box. Copper sheath tubular heating elements are silver brazed into a "Quik-Lok" brass header. For mounting in a closed tank, use a hand-hole.
  • Type GSU-CO urn heaters have a low liquid cut-out. An optional limit control which protects the heater when immersed. Cut-out assembly on all sized extends 3/4" above "B" dimension and increases minimum hand hold by 1/4".
• VL Over-The-Side Immersion Heaters
  • Ideal for heat applications -- for a wide variety of liquids. Glenn Type VL immersion heaters are heavy duty, coiled tubular heaters designed for immersion service by hanging over the side. Terminal ends are welded or brazed into a protective iron housing which is not affected by spillage, vapors, or moisture. Heat is generated in the coiled portion; therefore, the solution levels must be maintained high enough to insure complete submersion of the coils at all times. Thermostatic control may be obtained by using a Type AT thermostat with suitable thermowells.
  • Type VLC has a copper sheath element designed for water heating.
  • Type VLS has a steel sheath element designed for use in alkaline cleaning solutions. It is also used in alkalies such as sodium carbonate and cyanide solutions for plating brass, gold, cadmium, silver, and other solutions which will not attack steel.
