Product Lines
Circulation Heaters
Self-contained heating units designed for optimum operating efficiency and performance. All of the heat generated by the elements is immediately transferred to the medium being processed with minimal losses.
Duct Heaters: Standard and Finned Tubular
Process air duct heaters are used for tempering forced air in many industrial processes. Heater wattage is dependent on air outlet temperature (up to 1200°F [650°C]) and air velocity. Smaller duct heaters can be tandem mounted in place of one large unit to meet space limitations and simplify installation. Heavy wall Incoloy® tubular heating elements (field replaceable) provide protection against corrosive air environments and resistance to vibration when compared to open coil elements.
Enclosure Heaters
Tempco enclosure heaters are the answer to all your enclosure heater needs. Choose from four different styles of heaters:
- Ceramic Heater Enclosure Heaters
- Finned Strip Enclosure Heaters
- Silicone Rubber Enclosure Heaters
- Tubular Heater Enclosure Heaters
Flanged Aluminum Finned Immersion Heaters
The heaters are designed for fuel oil heating up to 250°F, and higher watt density versions are available for heat transfer fluid circulation systems up to 400°F. They can be used in static tank heating or flowing oil applications. The FAH series presents a smooth uniform heat transfer area to the flowing fluid, resulting in efficient heating with a minimum pressure drop.
Flanged Immersion Heaters
Flange heater construction lends itself to be easily and economically engineered into new equipment. Tempco also manufactures various style of heaters found in the Stock Lists that are direct replacements for heaters in many OEM applications.
In-Line Forced Air Heaters
Cartridge type forced air heaters are ideal for Small Volume Air & Gas Heating.
Pressure Rated Flanged Immersion Heaters
Steel and Stainless Steel Pressure Rated Flanges with sheath materials suitable for many large KW applications.
Screw Plug Immersion Heaters
Stainless Steel, Brass or Steel Screw Plugs in Four Standard Screw Plug Sizes—1″, 1-1/4″, 2″, 2-1/2″ can have an integral thermostat making them suitable for many applications.
