drum heaterDrum heater, also called pail heater or barrel heater, is large and standard sized silicone rubber heater that may easily be wrapped and secured around liquid containers. They are made of fiberglass reinforced silicone rubber laminated around a nickel alloy circuit. This construction provides an even heat transfer, which keeps contents at desired temperature and viscosity and limits scorching or degradation of sensitive contents.

Drum heaters are built to be tough, long lasting, and resistant to chemicals. Because few materials stick to its silicone rubber with fiberglass reinforced construction, it is easy to clean.  When not in use, it rolls for convenient storage.

drum heater temperature rise curveOptional, built-in thermostats are full-range adjustable and limit the temperature of the heater. Several factors affect the actual temperature of the barrel contents, including thermostat setting, heating wattage, type of contents and ambient temperature. Multiple heaters may be needed for heavy duty applications. The figure in the right shows the temperature rise curves of a 55 gallon drum with one 1500 watt drum heater and two respectively.

Features

  • Fits four standard drum sizes: 5, 15, 30, 55 gallon
  • 115V and 230V standard
  • 3 prong plug or pigtail termination
  • Internally grounded
  • Adjustable thermostat
  • Heavy hook and spring attachment
  • Resistance to many chemical substances

Standard Models

Drum Heaters are available for both metal and non-metal (poly or plastic) drums. The difference lies in the watt density. Metal drum heaters cannot be used on non-metal drums due to their higher watt density which will melt non-metal drums; however, nonmetal drum heater may be used on metal drums when necessary.

The table below lists the standard models we offer. Most of them or semi-finished parts will be in stock. So the delivery can be quite fast.
