Thermosafe Rigid Top Hat drum heating accessories from Grimwood Heating are made from a glass reinforced resin. They have handles fitted to each side to enable straightforward fitting and removal. Their overall height is 650 mm, they weigh 8 kg and their internal diameter is 620 mm tapered.
The Rigid Top Hat drum heating accessory is suitable for use with Thermosafe types A/B and the Faratherm. It is also able to be placed directly over the Faratherm when heating smaller drums.
These hazardous area products have been designed especially to minimise heat loss and increase the efficiency of the heater. It has been shown that drum wall temperatures increase by up to 40 degrees celsius when a Top Hat is being used. It has also been found that their use reduces the time needed to heat containers.
This product also comes in an economical, flexible version. Unlike the Rigid Top Hat, the Flexible Top Hat is not suited to use in areas that require a hazardous area certificate. They work by covering the exposed section of 205 litre drums increasing the maximum drum wall temperature by as much as 50 degrees celsius.
