Cartridge & Immersion Heaters

Hotwatt manufactures a wide range of cartridge heating units for a variety of applications.  This size, sheath, leads, terminals, wattage and voltage can be adapted to your heating requirements.  Hotwatt can provide you with heating units manufactured to your specifications to accomodate your application.  Hotwatt stocks all material for different diameter units.  Your order, specifying the wattage, voltage, diameter, length and lead type is readily and quickly fabricated from our inventory.  In addition, many standard sizes are available from stock for immediate delivery.
Air Process Heaters

Air Process Heaters can be utilized in a variety of applications including baking, drying laminating, metal working, packaging, plastic welding, preheating, sealing, soldering shrink fitting, synthetic fabric sewing.  These heaters will provide hot air and gas up to 1000°F(540°C) with infinite control by varying the voltage and air velocity supplied.  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 threading fittings, hose adapters, flanges, or custom fittings to your specifications.
Strip Heaters

Strip Heaters can be used in a range of applications such as dies, cylinders, kettles, molds, process machines, platens, tanks, and a variety of other applications.  These strip heaters may be used single or in groups to provide the required amount of heat.  For maximum distribution, it is recommended that the strip heaters be clamped securely to the area to be heated to prevent distortion or unequal expansion. 
Band Heaters

Band Heaters are extremely useful in areas such as cylinders, dies, drums, holding tanks, injections and blow molding machines, and plastic extruders.  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).  Holes and cutouts are available. Maximum wattage may be reduced with the addition of holes and cutouts. Drawing required for specific location.
Crankcase Heaters

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.  Hotwatt Crankcase Heaters are constructed of the highest quality corrosion resistance materials and sealed against moisture.

Tubular Heaters

Straight and Formed


The Hotwatt Tubular Heater has built-in resistance to shock, vibration, corrosion, and temperature extremes.  The heater is swaged, reducing the diameter of the metal sheath and compacting the insulation.  This insures rapid heat transfer and holds the coil in position for forming.  Many formations are available and long, trouble free service is available.

Ceramic Heaters

Ceramic Heaters can be used in copiers, dehumidifiers, glue guns, heat sealing tools, instrumentation, resisters, soldering and desoldering equipment and valve heaters.  These heaters have a ceramic body encasing a resistance element and packed within magnesium oxide.  The heaters are terminated with flexible insulated lead wires.  Temperatures for these heaters can be up to 1300°F (705°C).
