Cartridge & Immersion Heaters

April 23, 2014

Cartridge heaters provide localized heat to restricted work areas requiring close thermal control. Dies, platens and a variety of other types of processing equipment are efficiently heated. Closely controlled work temperatures up to 1400º F (760º C) are obtained by a combination of heater location and proper wattage output. Immersion heaters are ideally suited for heating various liquids. They are available in various sheath materials and watt densities tailored for your specific applications. Units may be supplied for single, three phase or three heat operation. The lead end of the unit may be sealed for extreme environmental conditions.

Crankcase Heaters

April 23, 2014

Crankcase heaters are used to overcome the problem of migration and condensation of refrigerant in the crankcases of compressors used in air conditioning and heat pump systems. They are designed to keep the crankcase oil at a temperature higher than the coldest part of the system to prevent migration. They are constructed of the highest quality corrosion resistance materials and sealed against moisture.

Ceramic Heaters

April 23, 2014

Ceramic heaters are a ceramic body encasing a resistance element and packed within magnesium oxide. Temperatures to 1300°F (705°C) for applications like copiers, dehumidifiers, glue guns, heat sealing tools, instrumentation, resisters, soldering and de-soldering equipment and valve heaters.

Band Heaters

April 23, 2014

Band heaters are used in multiple applications like cylinders, dies, drums, holding tanks, injections and blow molding machines, and Plastic Extruders as well as many other applications. The Hotwatt Standard Band Heaters are manufactured in one or two piece constructions with maximum inside diameters of 11 1/2" and 22 1/2" respectively. Three or more sections are employed when heaters of larger diameters are needed (as for blown film extrusion dies).

Tubular & Finned Tubular Heaters

April 23, 2014

Tubular & Finned Tubular heaters have built in resistance to impact, vibration, corrosion and temperature extremes. The heater is swaged, reducing the diameter of the sheath and compacting the insulation. This insures rapid heat transfer and holds the coil in position for forming. Many diameters, sheath materials and configurations are available.

Glasrope & Foil Heaters

April 23, 2014

Foil & Rope heaters are a self-contained one piece assembly. A resistance element is laminated between two layers of aluminum foil. This heater is ideally suited for area and surface heating applications. Operating temperatures up to 300º F (150º C). Sizes range from 1.25" to 60" wide with lengths of 4" and up. Glasrope heaters are flexible heaters available in various lengths, sheath materials and terminations. Operating temperatures up to 900º F (485º C).

Strip & Finned Strip Heaters

April 23, 2014

Stainless Steel Strip & Finned Strip heaters provide clean, dependable heat with sheath temperatures up to 1200º F (650º C) and watt densities up to 40 watts per square inch. Finned Strip heaters are available with aluminum or stainless steel fins. Mica Insulated Strip heaters are also available in various sizes.

Air Process Heaters

April 23, 2014

Air Process Heaters are used for: Baking, Drying, Laminating, Metal Working, Packaging, Plastic Welding, Preheating, Sealing, Soldering, Shrink Fitting, and Synthetic Fabric Sewing. Air Process heaters will provide hot air and gas up to 1400º F (760º C) with infinite control by varying the voltage and air flow. Units are fitted with a tubing "T" for convenient power lead outlet, while larger diameters can be supplied with post terminals on the sheath for direct electrical connections. For easier installation, Hotwatt can supply male or female NPT threaded fittings, hose adaptors (entry only), flanges, or custom fittings to your specifications. We can also provide temperature sensing control.
