Types of Drum Heaters
Drum heaters help ensure that a viscous liquid stays at the right temperature for processing, dispensing, pouring and other tasks. They can also provide protection against freezing and thawing of the container's contents. A variety of standard sizes and configure-to-order designs are available to meet a wide range of freeze protection, viscosity control and temperature maintenance needs for a number of industrial supplies.

These devices warm the contents of containers such as drums, barrels, IBC totes and pails by insulating and wrapping around them. The wraps are designed to stay in place and maintain a consistent temperature by using built-in thermostats and adjustable straps. They can be used in cold environments such as warehouses or outdoor storage areas, where heat can quickly be lost. The insulators and heating wraps can speed up the rate of heat transfer by reducing the amount of cold air entering the container.

Another type of drum heater is a rotary drum heater, which can be directly or indirectly heated. In an indirectly heated unit, the drum shell is heated and the material is exposed to the heated shell by direct contact. Tumbling flights or bed disturbers may be affixed to the drum to encourage agitation and more uniform exposure of the material to the heating elements. Indirect drum heaters can be more expensive than their counterparts.

IBC heating jacket , on the other hand, fits through the top bung hole in the drum and directly contacts the liquid inside. It can be used to heat the same liquids as drum blanket heaters but does so more quickly, and it can maintain a higher degree of temperature accuracy (within a range specified by the manufacturer) than band or blanket heaters. They can also be set to turn off automatically when temperatures reach or fall below a pre-set limit.

An explosion proof drum heater or tote heater can add an extra level of safety and security to hazardous industrial supplies. These devices are used to heat metal drums, containers and IBC totes by preventing them from igniting. They can also be configured to heat the contents of drums by immersing them in a heated bath of water.

Other ways to heat a drum or other container are to simply place it in the sun, which is effective in some climates but can leave the contents exposed to the elements. A drum or IBC can also be heated with a burner or furnace, but these methods require the use of chemicals and offer no level of temperature control.

Other types of drum heaters include the Powerblanket, which is a flexible insulated wrap that can be wrapped around a drum, bucket, pail or gas cylinder. It is resistant to most chemicals, easy to clean and slick, and folds up when not in use. The Powerblanket uses significantly less energy than a conventional band heater and is faster at warming and insulating. It can save time by speeding the flow of solid or semi-solid liquids and can help break up and melt dense or viscous materials for easier mixing, dispensing or transferring.
