Description

HEACOTEX SPCB Constant Wattage Cable

HEACOTEX SPCB is a constant-power, double-conductor heating cable for the commercial refrigeration industry. Its compact 3.7 mm external diameter allows installation in spaces where larger cables won’t fit. The heating section is identified by connection points marked with a continuous black line at 500 mm intervals. SPCB is supplied to specification, by the metre, or on rolls, with an external metal braid for additional mechanical protection and earthing.

Features

  • Constant power output — uniform heat along the full circuit
  • Compact 3.7 mm external diameter for tight installations
  • Double-conductor parallel construction
  • Connection points marked every 500 mm for accurate cut-to-zone
  • External tinned-copper metal braid for mechanical protection and earthing
  • Supplied per metre, on rolls, or to specification

Frequently asked questions

How is SPCB different from CPCB?

SPCB and CPCB are both braided constant wattage cables. SPCB is available in lower wattages (20 / 30 W/m) and is suited to process maintenance and pipe trace heating where lower wattages are sufficient. CPCB covers higher wattages (40 / 65 W/m) for industrial refrigeration.

What wattages does SPCB come in?

SPCB is available in 20 W/m and 30 W/m.

Can SPCB be cut to length?

Yes — SPCB is parallel-circuit and can be cut to length on site with appropriate termination components.
