Drum Heaters

Wrap Around Drum Heaters

When liquids are stored in drums or pails, maintaining a viscosity or 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, flexible Silicone Rubber Drum Heaters can keep these materials at proper handling or process consistencies. A spring-hook arrangement easily attaches these items to standard 5, 15, 30 or 55 gallon steel drums. Even heat transfer limits scorching or degradation of sensitive materials. Optional molded-in thermostats are full range adjustable or have fixed settings.
