Flanged Immersion Heaters

Flanged Immersion Heaters are designed for use in tanks and pressurized vessels to heat both liquids and gases. They mate to a companion flange that is either welded to a tank, wall or, for circulating type heaters, to a pipe.

• 150-lb forged steel or 316 stainless steel flanges
• Gasket Supplied
• Incoloy® 800, 316 stainless steel, steel or copper tubular elements
• Element hairpin bends are spanked in specially designed dies to re-compact the MgO insulating powder
• Silicone resin seal of elements standard
• 1/2″ OD thermowell for a 3/8″ diameter sensing bulb
• NEMA 1 electrical enclosure
• Standard heaters have elements wired into branch circuits having a maximum current of 48 Amps

Over-the-Side Immersion Heaters

Tempco Over-the-Side Immersion Heaters are specifically designed for heating fluids in tanks. Depending on the tank shape, size, accessibility and working area inside the tank, choose a round or L shaped heater. Standard sheath materials are Incoloy® 800 and steel with all wet-ted parts made with compatible alloys.

• Lightweight and Portable
• Easy Installation and Removal
• NEMA 4 Electrical Enclosure
• Single- or Three-Phase Wiring
• Steel Sheath Heating Elements
• NEMA 4 Terminal Housing
• Watt Density of 23 watts/in2 (3.6 watts/cm2)

General Purpose Tank or Reservoir Water Immersion Heater

• Immersion section of heater made of 316 Stainless Steel
• Cold riser extends to the top of container where control housing is located
• Cord set with 3-wire grounding plug is included for easy installation and wiring.
• Adjustable vapor-proof thermostat control with temperature range of 55°F to 115°F (±3°)
• Hi-limit cut switch set to 125°F (±4°)
• Stainless Steel mounting bracket also supplied for easy mounting
• Pilot light and on-off switch provided

Vertical Loop – Low Profile Immersion Heaters

• Used on open-top tanks for heating water, water-based solutions, citrus juices, plating tanks, oil tempering, salt baths and other mild corrosive solutions.
• NEMA 4 (moisture resistant) housing with integral grounding terminal is standard. Other NEMA ratings available.
• Low-profile design with adjustable SS mounting bracket.
• Optional Passivated, Electropolished, or Bright Annealed surface treatments available for Stainless Steel or Incoloy sheath designs.
• External power wiring options including flexible cord/plug, armor cable, braided or plain lead wire.
• Optional Hi-limit MI thermocouple on heater sheath.

Deep Tank/Sump Immersion Heater

These fluid immersion heaters are designed for top mounting in large or deep enclosed tanks having a manhole access or opening suitable to insert & attach the heater. They are usable for either outdoor or indoor applications, within exposed or in-ground tanks and sewerage sumps. They are designed for permanent mounting and can be sealed weathertight with supplied gaskets and adjustable riser fittings.

• 475 diameter Incoloy elements and stainless steel wetted parts standard ???? Designed for permanent installation in outdoor/indoor applications
• 2 ft to 12 ft vertical riser height (for thermostat designs)
• Weathertight mounting hardware supplied
• Riser adjustable to facilitate mounting variations
• NEMA 4 Electrical Enclosure with 3/4 conduit fitting
• 1-1/2″ Sludge legs
• Double-pole 60-250°F pilot duty thermostat
• Watertight thermowell sized for 3/8″ max. dia. sensing bulb
• 120V, 208V, 277V, & 575V versions available (consult Tempco)

Screw Plug Immersion Heaters

Screw Plug Immersion Heaters consist of tubular elements welded or brazed into a threaded screw plug which can then be inserted into a threaded opening in a tank wall or through a mating full or half coupling.

• Stainless Steel, Brass or Steel Screw Plugs
• Four Standard Screw Plug Sizes—1″, 1-1/4″, 2″, 2-1/2″
• Recompacted element bends restore insulation resistance after forming
• Thermowell for optional bulb & capillary thermostat, RTD or T/C probe
• Corrosion-Resistant electrical wiring hardware
• Four standard sheath materials — Copper, Steel, 316 Stainless Steel and Incoloy®800
• NEMA 1 round terminal housing
• Silicone resin element seal standard
