>> Induction drum heaters unique properties allow that the same equipment can heat drums and a variety of metal objects such as bottles, small reactors and process vessels. Full access while heating the drum makes it possible to simultaneously pump and stir.
In this way one can achieve a continuous supply of material at a controlled temperature and flow rate. Uniform heating and immediate response makes the heater ideal for emptying residues from drums, which reduces waste. Heat up times depend on the contents of the drum, an approximate temperature rise of a typical viscous organic substance is about 15°C per hour. Induction heating has proved to be 2 to 4 times faster than traditional heating methods. Some substances need to be maintained at a certain temperature. This can be achieved with our induction heater.
When certain substances need a specific temperature or a heating curve, you can use our power regulator (BF400) or Control Panel. These should be placed in a safe environment. The Control Panel is more advanced than the BF400. It has digital temperature control on / off, timer, solid state relay with heat sink, main switch, fuse, circuit breaker 3-mode (Control – OFF – ON).
Designed to heat 200 liter drums or smaller steel vessels, induction drum heaters have a single induction coil, completely encapsulated in a cylinder made of glass-reinforced resin specially developed for use in chemical plants. The cylinder is simply placed over the barrel. Physical contact is not required. The Heater is connected to the mains supply (1 phase, AC) which directly generates heat uniformly in the barrel walls. Energy transfer takes place via magnetic fields. Since there are no hot parts the heater remains considerably cooler than the drum that is heating.
The total lack of hot elements and encapsulation of all electrical components allows our induction heater to be used in hazardous areas Zone 1 and 2 (see below). It follows the Directive 94/9/EC of SIRA. The heater has both ATEX and IECEx certi-fication (SIR 08.0037X) from SIRA. Uniform heating with no “hot spots” reduces the risk of product degradation. Accidental spillage does not constitute a fire hazard and staff can work safely in close proximity.
