Applications
Dies, Molds, Plastic Forming and Sealing, Tank and Kettle Heating. For specific applications, correctly
rated elements should be used to prevent overheating and to ensure long life. A guide to correct watt densities for specific applications is shown below.

Features

  • The Hotwatt Stainless Steel Strip Heater provides clean, dependable heat with sheath temperatures up to 1200F and watt densities up to 40 watts per square inch.

  • Because of the seamless stainless steel sheath, Hotwatt Ceramic Insulated Strip Heaters are dimensionally stable in milled slots.

  • Made in U.S.A


Construction

  • Maximum wattage limited by 18 amp maximum at 240 volts for catalog numbers CS-42.5
    and longer. Any wattage is available between minimum and maximum without effecting price.

  • Unit lengths between and longer than those listed may be ordered.

  • Red catalog number denotes stock item. See stock section for specific ratings.

  • Standard termination is Type OF. Units under 8" long, standard termination is Type SSA.


Standard Termination

Type OF:  Offset at one end.

How To Order
After determining the wattage required and the line voltage available, determine
the physical space available for heaters and the number of heaters required.
Review Strip Heaters In-Stock.
Specify:  catalog number, wattage, voltage, termination, and special
features if required.
