For heating viscous materials in standard drums Scarlet offers flexible electric surface heating pads which can be wrapped on drums to melt the material in the drums. These heating pads are made with nichrome wire and fiberglass cloth/ Teflon coated fiberglass cloth. Scarlets heating pads are highly flexible and will have a proper contact with the surface of the drum allowing no air gap. These pads are highly efficient in producing uniform heat to the entire barrel. The element in the heater is insulated with fiberglass yarn and the heater is backed with 40mm thick insulation to avoid the heat losses to atmosphere. On each drum a single pad or multiple pads can be used. Available in different wattages.
