Induction drum heater THERMOSAFE®

for liquids

The THERMOSAFE® is a single induction coil, wholly encapsulated in a cylinder made from a glass reinforced resin specifically developed for chemical plants. The cylinder is simply placed over the drum. Contact is not required. The coil is connected to a single phase AC mains supply and generates heat direct and uniformly in the drum wall. Energy transfer is by alternating magnetic field and thus there is no heat transfer by the conventional and inefficient means of radiation or convection. As there are no hot elements, the heater remains substantially cooler than the drum being heated. SAFETY The complete absence of hot elements and the encapsulation of all electrical components enables unattended use, overnight if required. THERMOSAFE® can even be used in hazardous areas. Uniform heating without hot spots reduces the risk of product degradation. Accidental spillage does not present a fire hazard and personnel can work comfortably in close proximity. Together, these features allow material to be heated at point-of-use, thus eliminating the transport of hot drums. EFFICIENCY The low system temperature and lack of heat transfer contribute to high efficiency of the induction heater. Power usage is extremely low at only 2.25kW. Although originally designed with safety in mind, the heaters have won several awards for efficiency and productivity. Independent figures indicate energy savings of over 50% when compared with conventional radiant drum heaters, and more than 90% in comparison with drum ovens.
