Series heating cables - RFS

 
 

At Elementos Calefactores AS, we are experts in manufacturing series type flexible resistance, for all kinds of applications and heating systems.

 
   
 

Description of Series heating cables

The series heating cables or flexible series resistance, models RFS and RFSS, are flexible heating elements composed of a woven glass fibre core, around which a Ni-Cr 80/20 heating wire is wound. It is then vulcanised with a thermal silicone covering (the coverings may vary according to applications or needs) and the ends can be fitted with electrical conductors or connectors ready for connection.

Applications for flexible resistence

The Series heating cables have many applications, these are some examples:

Radiant floor heating systems:

  • Homes and general construction.
  • Industrial buildings.
  • Temples.
  • Museums, theatres, cinemas.
  • Farms, veterinary centres, terrariums.
  • Greenhouses.
  • Agriculture, viticulture, etc.

Special heating systems:

  • Pipe tracing.
  • Tanks and deposits.
  • De-icing systems.
    1. Roofs and rooftops.
    2. Driveways and ramps.
    3. Gutters and drainpipes.
  • Barrels.
  • Compressors.
  • Boilers.
  • Any application requiring flexible heating.
 
 

Supply

  • In reels.
  • In finished sets, according to length.
  • With Insulation diameters of: 2.9mm, 4mm (Standardised), 5mm, and 6mm.
  • By request we can manufacture different voltages, power ratings and diameters (minimum 500 metres).
 
 

It is important to specify the end termination when ordering:

  • Cold tails.
  • Faston 635 connectors.
