The high quality silicone heating element of the HISD/E side drum heater is stitched into an insulated jacket made from a highly durable flame retardant polyester fabric and insulated with a thermally efficient, flexible E-glass fibre blanket. The construction is complete with easy to use quick release buckles for simple installation and removal, 4 metres of robust power cable and either a 0°C to +40°C or 0°C to +90°C capillary thermostat (digital option available), a 145oC over-temperature limiter for further protection and has a class II double insulated element meaning that it far exceeds European safety standards. It also provides an unrivalled solution for frost protection applications. * *Minimum to Maximum - The diameter doesn’t guarantee a perfect fit, if fitting to the largest diameter the edges of the jacket may not touch. The optimum diameter is midway between the two given diameters.
