What is Heating Cable?

Heating cable, also known as insulated heater cable, is an essential component used to provide controlled heat in refrigeration, food warming, and industrial applications. It consists of a resistance wire wound around a heat-resistant core, insulated with PVC or silicone rubber (SRG). Some variants include fibreglass or aluminium braid for added durability and protection.


How is Heating Cable Used?

Heating cable is primarily used to prevent condensation and ice formation in refrigeration systems. It is commonly installed:

  • Around cool room and freezer doors to prevent ice buildup.
  • In refrigerated display cabinets to maintain visibility and food quality.
  • Inside drain lines to prevent freezing and blockages.
  • In custom food warming applications to maintain consistent temperatures.
  • In industrial processing where heat needs to be applied to specific areas.

The cable can be installed using self-adhesive aluminium foil, tape, or mounted within grooves and channels to ensure efficient heat transfer. Proper spacing and installation prevent overheating and extend the cable's lifespan.
