Earth Screen Heaters

Holroyd manufacture flexible silicone heaters with an inbuilt earth screen that offers protection in case of puncture of the outer insulation layer resulting in contact with the live heating circuit. The full coverage Earth Screen provides continuity of any earth fault back to the protection device of the electrical supply such as residual current device (RCD) or ground flow circuit interrupter (GFCI). Any electrically conductive surface that the heater is fitted to should be earthed separately. The flexibility of the Earth Screen heaters allows them to be used effectively on convex, concave and flat surfaces. This is particularly useful when the heaters are required to be flexed within the application. A self-adhesive backing can be supplied to hold these heaters effectively in place if required.
