Drum Heaters

A reliable source for Electric Heaters information and leading Electric Heaters Companies & Manufacturers.

Drum heaters come in various shapes and sizes, but they always serve the same purpose: to raise the temperature of liquids housed in standardized metal drums. These gadgets can be classified into a few different groups. Read More…

Drum Heaters There are a few different styles of drum heaters out there in order to accommodate a wide range of applications and industries. While the designs may be different, these electric heaters are all manufactured in a way that allows them to increase the overall temperature of a liquid that is being stored within a container, or drum. The reason why the word container is thrown around is that some drum heaters have the ability to heat multiple containers instead of being restricted to one drum at a time. The type of drum heater that you require is all based on the individual needs and requirements that are present in your specific application. Whether you require a large drum heater, such as a drum oven, or a mobile single drum heater , finding the right drum heater manufacturer can save you time and money.

Depending on the model, a drum heater may warm many containers or simply one at a time. Drum warmers are available in various designs due to the multiple sizes available for drums. Some drum warmers reduce viscosity to make pouring or mixing easier, while others are merely designed to keep liquid from freezing.

Drum ovens are often known as the biggest drum heaters. On a pallet, a mobile version can carry a single drum or approximately four barrels, while massive, heated room-sized systems can commonly store several dozen drums. These heating chambers can warm up many barrels and keep them at a consistent temperature for long periods, but they are often expensive and energy-intensive. More efficient are transportable drum heater ovens and machines that only warm one barrel at a time.

Materials Used in Drum Heaters

  • A drum heater's heating element is PTFE-coated and sandwiched between two double layers of siliconized fiberglass. The multilayer insulation ensures a high level of electrical safety.
  • The siliconized fiberglass sheets are vulcanized and bonded under heat and pressure to make a material that can sustain harsh industrial use and is very flexible, resilient, and durable.
  • A tension spring provides optimal contact with the barrel, rapid installation, and removal.

Types of Drum Heaters

  1. Cabinet Heaters

    These can heat drums or varying-sized containers. They are usually equipped with a fan to improve air circulation and may be loaded and unloaded using a forklift.

  2. Insertion Heaters

    They have heating components that fit into conventional bung apertures on the top of a drum. Because the heating element is submerged in the heated media, the sheath materials and watt densities must be chosen according to the kind of fluids to be heated.

  3. Tunnel Drum Heaters

    Tunnel drum heaters are heated with a conveyor-fed oven. They can be incorporated into automated drum handling systems and support a first-in, first-out product flow.

  4. Wrap-around Heaters

    Flexible heating components are built into a jacket or band clamped or fastened to the drum.

Types of Drum Heaters

Construction of Drum Heaters

  • On the one-piece type, the drum heater has a spring-loaded handle and a snap-action bi-metal temperature controller (220 °F or 104.4 °C).
  • The drum heater's two-piece structure includes a latch and trunnion fastener, as well as a bulb and capillary thermostat (250 °F or 121.1 °C).
  • They can be tied around, placed inside, or heated together with the contents of the container.
  • All drum heaters are thick gauge sheet steel with a double skin design that houses the inner surface's electric heating components.
  • Reinforced thermal insulation is installed on the heating components to prevent heat loss through the exterior wall.

Working of Drum Heaters

  • A thin silicone coating is applied to the steel drum heating band.
  • These bands act as insulators and may be placed up to three times to aid heating, contributing to keeping things heated and above the melting point.
  • For these heaters to perform correctly, the drum must be completely sealed.

Benefits of Drum Heaters

  • Because of its optimum balance of power, thermal insulation, and temperature control, the drum heater is meant to be energy efficient.
  • The ability to manage the temperature of the drum's contents allows for quick heating of liquid to the required temperature, facilitating removal and maximizing the use of the liquefied product.
  • Drum warmers keep the contents of drums warm and secure, preventing frost damage and distortion.
  • They ensure viscosity control, freeze prevention, temperature maintenance, and solids melting by providing optimal and consistent heating to drums.
  • Heater burnout is not a problem since energy efficiency is maintained.
  • Drum heaters are simple to use and require minimal user effort.

Applications of Drum Heaters

  • Because certain oils, for example, thicken at lower temperatures, induction heaters can be used to lower the product's viscosity, making it simpler to pump or mix.
  • Materials that crystallize at cooler temperatures, such as honey, can be kept at warmer temperatures to avoid this.
  • Drum induction warmers are frequently used to store goods that freeze in cold settings, such as paint.
  • These devices can heat barrels to maintain viscosity, liquidity, and fluidity.
  • In some cases, heat may be used to modify the molecular characteristics of the materials housed within a drum.
