Clamp on heaters are ideal for applications where short heat up times and high temperatures need to be achieved. An optimum watt density specially designed heating element is sandwiched between two steel plates and formed in a semi-circular shape to fit around the outside of the drum, held on by a steel band with quick release toggle fasteners. Clamp on heaters are lightweight, portable and can be moved from drum to drum with ease. If more heat is required, extra clamp on heaters can easily be fitted. The clamp on heater is ideal for applications where the material or solution to heat cannot come into direct contact with the heating element. This makes them best suited for closed drum situations, e.g. Solvents.
