Low to Medium Watt Density - The Hotwatt Square and Rectangular Cartridge Heater is designed to distribute maximum heat within a desired area. Because they are completely enclosed, square units will furnish more usable heat for a given wattage than a comparable strip heater attached to the exterior of a mod, platen, or other equipment.(read more)
Tubular heaters have built in resistance to impact, vibration, corrosion and the 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 configruations are available.(read more)
Foil heaters are a self contained one piece assembly. A resistance element is laminated between two layers of aluminum foil. Operating temperatures up to 300 Deg. (150 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 900 DEG. F (485 C.).(read more)
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.(read more)
