Halogen-Free Fire Retardant Conduit

Supplier: Calair Pipe Systems

Breakthrough range of halogen-free, fire retardant conduit expands for surface, enclosed and underground uses.


Now available in diameters from 20 – 110mm in response to demand in Australia and New Zealand, the conduit is especially formulated to meet high fire safety requirements in surface and sub-surface applications.

Producing no corrosive or toxic flue gases in the event of a fire, the flame-retardant, low toxicity HFT range of polymer conduit is designed for use in situations where there are high concentrations of people, high concentrations of assets or risk of high costs due to production interruption.

Applications include advanced technology industrial plants, mines, tunnels, airports, subway systems, power plants, oil refineries, lifts, emergency plants, ships, aircraft, trains, computer and telecommunication installations. It can also be used in hospitals, schools, hotels, museums, theatres, shopping centres and conference centres.

The HFT conduit is complemented by both standard glued type fittings or high performance IP67 fittings

CalAir expanded conduit system is designed for radically simplified erection, disassembly and recycling within a fraction of the time taken to construct and change traditional metal alternative conduits.

Weighing just one eighth the weight of galvanised steel, for example, it can be easily installed with far fewer OHS issues than heavier materials. Also, its flexibility enables it to confirm readily to irregular contours, such as those encountered in tunnels and trenches.

Properties of the new HFT range include:

  • No fire transmission or fire propagation
  • Low density and minimal formation of flue gases in the event of a fire
  • High temperature resistance
  • Low toxicity, non corrosive
  • High impact properties and stiffness
  • Excellent electrical and dielectrical properties
  • Available in sizes 20-110mm

The range is manufactured to the same standards of durability and quality as CalAir gas and liquid pipe systems used in 6,500 applications in Australia and internationally.
