We have utilized superior temperature stability of PTFE (-200°C to 260°C) to develop safe, efficient and long-life PTFE insulated heaters. Our heating elements are made for various applications:
Round, single and multi-strand normal heaters. We also provide slight oval, flat strip or twin parallel-laid constructions for better heat transfer
Surface heating wires: Multi-conductor bonded flat cables or woven flat cables for integrated surface heating.
Outdoor use: 1, 2, 3 strands helically wrapped on Glass Fibre cord with PTFE insulation and Nickel Plated Copper/Stainless Steel braid shield for outdoor use.
Floor heating elements: Insulated heating wire with parallel-laid temperature sensor wire of pure Copper or Silver Plated Copper having high temperature coefficient of resistance, under a common PTFE jacket (with zero moisture absorption) for floor heating.
Remote area heating elements: Fixed wattage and fixed length heating elements with integral heating leads under common PTFE cover with same or different colour to identify the heating zone, for heating of remote areas
Construction
Three main parts of heating wires and devices are:
Heating resistance wire capable of long-life stability at the required temperature. These are single or multi-strand, or helically wound 1, 2, 3 strands (on glass-fibre cord) of plated/unplated Copper, Copper alloy, Stainless Steel or resistance alloy.
PTFE insulation with the desired Radial Thickness of Insulation (RTI), minimum 0.15 mm to maximum 1.5 mm. This insulation is guaranteed concentric multi-layer tape-wrapped and heat-fused.
Temperature Sensor; protection system such as braid shields for ease of handling.
Wires for floor heating
Following is a list of standard Heating Elements for use at 230 V AC RMS. The typical product form consists of round Heating Wires with Stainless Steel Braid Shield and PTFE jacket with final OD 1.8 mm to 2.2 mm. Conductor used for heating element is multi-strand (dia 0.25 - 0.68 mm).
