PCR+C CONSTANT-WATTAGE HEATING CABLES

PCR+C

> Heating Cables Range

PCR+C constant-wattage heating cables for refrigeration applications are available in 30 W/m and 40 W/m versions. They consist of heating modules that deliver a constant heat output, regardless of the ambient temperature. Featuring a highly flexible silicone sheath, these cables can be cut to length on-site and branched from a single power supply point (power is available along the entire length of the cable). They are designed exclusively for integration into cold room door frame gaskets and must not be used for general temperature maintenance applications.

Principle

PCR+C heating cables feature contact points every 60 cm; heating begins at the very first contact point. Connection is made at only one end of the heating cable.

  • Do not use on plastic piping (multilayer, PVC, etc.).
  • Strictly follow the instructions for use.
  • Warranty scope: max. 120°C when energized / -70 to 200°C when de-energized.

Features

  • Available power ratings: 30 W/m and 40 W/m (± 5%)
  • Power supply: 230 V
  • Max. energized temperature: frost protection
  • De-energized temperature range: -70°C to 200°C
  • Max. circuit length: 15 m
  • Diameter: 4.4 mm
  • Min. bending radius: 6 x cable thickness
  • Flexible sheath
  • Conductor: nickel-chrome or nickel-copper
  • Cross-section: 2 x 0.25 mm²
  • Conductor insulation: silicone elastomer
  • Contact points: 0.6 m
  • Cut-to-length on site
  • Tinned copper braid for mechanical protection and earthing

Applications

The PCR+C cable is primarily intended for use in industrial refrigeration applications:
> In cold room door gaskets
> For anti-condensation purposes
> Crucially, do not use for temperature maintenance

We recommend installing a control thermostat.

Installation instructions

For optimal effectiveness and safe installation, please follow the TECHNITRACE instructions.

Benefits

  • No thermal aging of the heating element (alloy)
  • No start-up current spikes—unlike other technologies—ensuring effective electrical protection
  • Integrated cold lead due to the technology used
  • Can be cut to length on-site as required (modular)
  • Allows for branches and tap-offs from a single power source (power available along the entire length of the cable)
  • Highly flexible installation
  • Standard 230 V version available

General characteristics

  • Thermal protection: rated current × 1.25
  • Residual current protection: 30 mA (mandatory)
  • Maximum circuit length: 15 m
  • Maximum exposure (energized): frost protection only
  • Maximum exposure (de-energized): -70°C to 200°C
