The heating bands for drums They are used to heat or maintain at the desired temperature oils, waxes, resins, adhesives, and other products whose viscosity changes with temperature. The Holity range includes compact belts and wraparound jackets for containers of different capacities, including metal drums, some plastic drums, and IBC tanks. The choice must consider container size, material, product content, required temperature, power, and working environment conditions.
Some models use a narrow band with a heating element and are secured by springs or tensioning systems. They primarily heat the area of the drum to which they are applied and are practical when the device needs to be mounted and removed frequently.
For example, the Holity catalog includes bands for 10- and 50-liter metal drums with thermostats adjustable up to 130°C. Compatibility and maximum temperatures should always be checked for each individual model.
Liners cover a larger surface area of the container and can incorporate insulating materials such as fiberglass, nylon, polyurethane, or coated fabrics. They are available for 25, 50, 100, and 200-liter drums and for larger-capacity tanks.
A larger heated surface can promote more even heat distribution, but heating time and consumption also depend on power, ambient temperature, insulation, container material and product characteristics.
The nominal capacity and diameter must be compatible with the dimensions declared by the manufacturer. A band designed for a specific drum must not be arbitrarily adapted to containers of different sizes.
There is no universal temperature that applies to all drums and products. The catalog includes thermostats with ranges such as 0-90°C, 0-130°C and 0-150°C, but the value that can be set by the device does not necessarily coincide with the temperature suitable for the container or substance.
For plastic drums, only use models declared compatible and respect the temperature indicated by the container manufacturer. It is incorrect to apply a general rule that all plastic drums can be heated up to 90°C.
The product contained may also impose lower limits: before heating, check the process temperature, thermal stability and the indications in the relevant technical documentation or safety data sheet.
The power expressed in Watts indicates the nominal absorption of the heating element, but it does not by itself allow you to predict the time needed to reach the desired temperature.
The result depends on volume and initial temperature of the product, specific heat, viscosity, drum material, heated surface, insulation and ambient temperature. Therefore, a more powerful model is not automatically the best choice for every application.
If the goal is primarily to maintain a temperature already reached, the needs may be different than those for heating a very cold or partially solidified product.
Heating strips must be installed and used according to the manufacturer's instructions, checking the supply voltage, protection rating, cable integrity, and proper contact with the enclosure. Several Holity models are intended for indoor industrial environments and feature, for example, an IP40 protection rating.
The cost varies mainly depending on dimensions, power, thermostat range, insulation materials, heated surface and container capacityA compact belt for a small drum and a jacket for an IBC meet very different needs, so it is better to compare technical characteristics rather than using rigid price ranges.
Explore the selection of heating bands for drums on Holity and compare models by capacity, size, compatibility with metal or plastic, power and thermostat adjustment range.
For laboratories, factories and industrial supplies you can request a personalized quote indicating the type of container, dimensions, substance to be treated and required process temperature.
Is a tight bandeau or a wrap shirt better?
It depends on the application. The compact band heats a smaller area and is easy to move; the jacket covers a larger surface area and is ideal when you want to distribute the heat over a larger portion of the drum.
Can I use any band on a plastic keg?
No. You must choose a model specifically compatible with plastic containers and respect the temperature limits indicated by the manufacturer of the drum and the band.
Does a maximum temperature of 150°C mean I need to set the band to 150°C?
No. This is the adjustment limit for specific models. The actual temperature must be chosen based on the container and the product being heated.
Can I mount the band on a barrel of a different diameter?
Only if the diameter falls within the manufacturer's stated range. The band must be installed in the intended configuration and must not be bent or overlapped unless the manual permits.
How does consumption change with ambient temperature?
A colder environment generally increases heat loss and may require more energy to reach or maintain the setpoint. Actual consumption, however, depends on the entire system and cannot be determined by nominal power alone.
Can heating bands be used in ATEX zones?
Only when the model has the specific suitability required for that environment. Normal industrial use or the CE marking do not automatically equate to ATEX certification.
