Drum heaters warm thick liquids and gels to reduce their viscosity, so they’re easier pour and bottle. These liquids include tar, varnish, resin, grease, and other dense liquid substances. Typically, a drum heater or pail heater is an electric-powered belt that is wrapped around the outside of the drum or pail. There is also a drum heater blanket that wraps around the entire drum and is fully insulated. Zoro also has a super selection of commercial and industrial cabinets, modular drawer cabinets, and bin cabinets too.
