Keeping Industrial Drums Warm

Band Heaters

Types of band drum heaters –

Band drum heaters are an inexpensive and convenient method of keeping liquids stored in any size drum at a constant temperature regardless if the drum is made of steel, plastic, or fiber. The type of band depends on the material to be heated and the type of drum. Drum band heaters easily slip on and tighten for a snug fit using radiate heat to control the temperature of the drum’s contents. As with all drum heating devices, band drum heaters come with adjustable thermostats with settings ranging from 50 to 425 degrees Fahrenheit making them adaptable for any liquid. Small and portable, they can be used to heat products regardless of the location or ambient weather conditions. All that is required is a reliable power source. Heating bands can be made from plastic, aluminum, vinyl, silicone, or fiber. The different types of materials are designed to meet the conditions of different barrels as well as their liquids. Using indirect heating elements, band drum heaters keep the contents of a drum heated by raising the temperature of the drum wall, which radiates heat to the liquid. A nice safety feature of band drum heaters is their ability to warm substances that could be volatile or explosive since the heating elements never have direct contact with the drum’s contents. Band drum heaters come in varying widths from six to eight inches up to a couple of feet. How wide the heater is depends on the substance to be heated, how rapidly the heat needs to spread, and the size of the drum. The wider versions have more heating elements and work faster.

Reasons to use a band drum heater –

Certain liquids, when in storage, can solidify if left to set and lose their viscosity. In order to keep them in liquid form, the temperature of the liquid must be kept constant and regulated. The natural solution would be to raise the temperature in the storage room. Though that would be logical, it would also increase energy costs and usage. Having a device that can be easily attached to a drum to keep a liquid at a set temperature has the desirable effect of keeping energy costs down and avoiding the need to replace contaminated liquids.

There are many ways of keeping drums heated from large cabinets capable of holding several large drums to blankets wrapped around them. Of all of the different methods, drum band heaters are the most economical with cabinets costing over $10,000 and blankets being well over a $1000. Drum band heaters are useful for heating a few drums needing to be stored outside or left stored until the liquid is needed.

Unlike cabinets, platforms, and blankets, band drum heaters are very convenient and can be easily moved from one drum to another instantly. Their portability makes for easy storage and immediate accessibility. Other methods of heating drums tend to be cumbersome and require planning when being moved from one drum to another. Drum heating cabinets are never moved and are designed to used by large companies with multiple barrels to store.

Different types of band drum heaters –

Band drum heaters come in different widths, thicknesses, diameters, type of heating elements, thermostats, heating capabilities and materials. All varieties have a clamping system to keep them in place to prevent slippage and hold them snugly to the drum. The type of heater you purchase will depend on what is being heated and the size of the container. Band drum heaters are capable of being fitted to a small bucket or very large drums with ease.

Other factors to consider when shopping for a drum band heater is the bands sturdiness and wattage. The thicker the band the more likely it will be able to withstand constant usage. Economical bands with a single layer of thickness are for short term storage of liquids while bands with two or more thicknesses tend to last longer and are capable of being attached multiple times for longer periods of time. The wattage for most band drum heaters varies between 150 to 1200 watts depending on the size of the band and the amount of heat required.

  • Silicone – Silicone band drum heaters have several features that make them ideal as a heating device. Since silicone has a low mass, it does not interfere with the passage of heat from the heating element to the contents of the barrel. Most silicone band drum heaters come with an electronic thermostat that is easy to set and control the flow of heat to the liquid.
  • Metal – As with all band drum heaters, metal drum band heaters come in varying widths and thicknesses with a dial thermostat. Unlike other band drum heaters, metal heaters come in direct contact with the container without a protective covering over the heating element. Workers need to be especially careful when near the heater. Metal drum heaters are locked in place with a simple lever locking mechanism.
  • Fiberglass – The unique feature of fiberglass band drum heaters is their flexibility. They are adaptable to fit all shapes of drums and are reinforced with rubber, which helps them fit the curves and circumference of drums. They clamp on using a spring and hook latch that snugly holds the heating band in place. When necessary, two fiberglass heaters can be used to maintain uniform temperature.

The cost of a band drum heater –

Of all the types of drum heaters, band drum heaters are the most economical. Prices vary between a little over $50 to slightly over $800. The cost depends on the sturdiness of the band, the amount of electricity required, the thickness, and the type of heating element. The more powerful and efficient band heaters may cost a bit more but will give years of usage.
