A drum heater is a belt or band designed to wrap around a drum and heat the material inside. They are typically used to speed the flow of viscous materials like greases, oils, plastics, and adhesives, and to maintain liquids at a constant temperature.
Drum heaters are constructed with high temperature resistance elements and a reinforced insulation jacket, generally made of silicone rubber. The panel wraps around the drum, secured tightly by spring attachments or banding materials either included with the heater or provided separately.
Drum heaters may also come equipped with a thermostat for precise temperature control which may be necessary for volatile materials.
