Drum Heating - Features and Benefits
Inditherm provides a range of heated jackets to fit standard 205 litre (55 gallon) drums. They have also developed base heaters for applications where this is more convenient or if additional heat is needed due to demanding process conditions. All jackets and base-plates use Inditherm’s patented carbon polymer technology to ensure that heat is applied evenly over a large surface area, giving high thermal transfer characteristics that deliver highest heating performance at lowest running cost.
Practical & Versatile
Heated jackets are designed so that they can be fitted and removed quickly and easily. All jacket systems include an insulated lid for added efficiency and can be customised with cutouts, for example to cater for inlet and outlet pipes. Precise digital temperature controls are provided to meet process requirements, with the option of fixed output for simplicity or fully variable temperature to cater for changing process conditions or needs. Inditherm technology ensures there are no hot spots, such as can be associated with trace heating wire type designs.
Base heaters are placed under the drum to provide extra heating thus ensuring that cold conditions under the container do not adversely affect the overall heating or create conditions at the bottom of the drum that impact on contents by preventing any heat loss. The combination of jacket and base heater can deliver extra warming where process conditions are particularly demanding or if faster heat-up times are needed.
Inditherm systems all run at extra low voltage (SELV) to ensure operator safety at all times and under any conditions. High performance thermal insulation is integrated into all jackets, not only ensuring maximum heating efficiency and low running cost, but also preventing any risk of operators touching a hot surface in higher temperature applications.
The design of Inditherm drum jackets and base heaters take into account the harsh environment that the containers can be used in. The heated jackets are manufactured with industrial grade PVC outer covers for unrivalled durability. The insulation is provided using closed-cell foam to give not only high thermal efficiency but also long life in an industrial environment unlike other low quality products manufactured using inferior insulation such as glass fibre (e.g. rockwool). The base heaters are constructed using aluminium support plates and I-beam sections for extra strength combined with low weight for ease of handling.
The heated drum jackets use Inditherm's patented, extra low voltage carbon polymer technology to provide the heating. The construction is in two parts: a heated jacket that surrounds the walls of the drum and a removable, insulated lid. Unlike other forms of heating, there are no hot spots. The base heaters use the same technology, giving the same advantages. Inditherm also produces unheated jackets that are suitable for materials where insulation only is required to retain heat.
All products in the range have high thermal insulation fully integrated to ensure that heat is directed efficiently into the container. This ensures highest energy efficiency, lowest running cost and significant environmental advantages.
The energy saving provided by Inditherm heated drum jackets is very significant compared to other products. Annual running costs are typically very much lower than those of trace heating type drum jackets. Base heaters offer similar cost benefits due to the thermally efficient design.
