SEFAR PowerHeat NT – heating fabric

Can be cut to almost any shape: the conductive wires are at right-angles to the flexible power supply bars and distribute the electrical power along their entire length and thus evenly heat the whole surface area.

The electric power supply bars are placed side-by-side, e.g. along one fabric edge

3D-shaping capability

Compatible with injection/back-injection mold processes

Compatible with thermoforming processes

Quick heat-up due to its light weight

No hotspots

Energy efficient: high temperatures are attained with low electrical power

Up to 1000 W/m² heat transfer when exposed to air

Up to 10-25 kW/m² heat transfer possible when exposed to liquids and composites


High air permeability

A hole has been cut into the fabric; in spite of that, the adjacent area is still heated.
The area immediately alongside the power supply bar stays cool.
