When liquids are stored in drums, maintaining a viscosity or a certain temperature is often necessary. Examples are adhesives, mastics, resins, grease, paint, oils, and many liquid food products. Where external heating is required or preferred, Drum Heaters can keep these materials at proper handling or process consistencies. A Quick release arrangement easily attaches these items to standard 210 lt steel drums. Even heat transfer limits scorching or degradation of sensitive materials. Thermostats are full-range adjustable.
