WIRE HARNESSES

All of Backer-Springfield’s heater wires (see Heater Wire product) are available on spools in bulk, but we also have the capability to make heater wire harnesses. In order to meet your exact specifications, you simply specify your necessary wattage, length, and terminations.

Backer’s heater wire harnesses are available in 3 different constructions (per European standard).


Single-Ended Wire Harness

Single-ended harnesses have the leads exiting on the same side of the harness. The final insulation layer can be silicone or PVC.


Double-Ended Wire Harness

Double-ended harnesses have one lead on each end of the assembly. These can be made with PVC or silicone insulation and can be finished with glass or aluminum braid for abrasion resistance.


Double Insulation Wire Harness

Double insulation harnesses are designed to meet Class II standards per IEC 60335-1. This European standard requires 2 layers of insulation each of which is at least 1mm in thickness. PVC or silicone insulation can be used in either layer of this construction.

Some of the applications for heater wire harnesses are:

  • Foodservice Equipment (food preparation equipment, service equipment, warmers),
  • Refrigeration (commercial refrigeration, consumer refrigeration, walk-in coolers, walk-in freezers, refrigerated transport),
  • Transportation (side mirror heaters, seat heaters, fluid warming, wiper heaters), among others.

 

Backer-Springfield is a manufacturer of high-quality heating products and, as such, we are only setup to sell to resellers and O.E.M. manufacturers. We are unable to fulfill requests direct from consumers. If you are a consumer seeking a replacement element for your appliance, please contact the manufacturer of your appliance or your local professional service technician for information on the required heating element(s).
