Faratherm Induction Base Heater

The Induction Base Heater works on exactly the same principle electrically as the Thermosafe heater, but permits huge additional power to be delivered into the base of a drum. For melting solids or very quickly heating highly viscous liquids this will dramatically drop the total time required to reach operating temperature. It can also be used as a stand alone item, or with one of our insulation only jackets. The base heater is also certified to operate very safely with HDPE plastic drums and smaller containers can be placed onto its hot plate if you require. Where hazardous area certification isn't essential, our DIGIHEAT base heater can be used. Designed for use with or without a Thermosafe Drum Heater, it has an integrated digital temperature indicating controller. Efficiency The low system temperature and lack of unwanted heat transfer contribute to the high efficiency of the induction heater. Power usage is extremely low at only 2.25kW. The heaters have won several awards for both efficiency and productivity. Independent figures show energy savings of over 50% compared with conventional radiant drum heaters, and higher than 90% in comparison with drum ovens. Safety The complete absence of hot elements in our Induction Heaters, including the encapsulation of all electrical components enables unattended use, overnight if required. Thermosafe and Faratherm can be used in hazardous areas Zones one and two, as the heaters possess both ATEX and IECEx certification from SIRA. Uniform heating without hot spots significantly reduces the risk of product degradation. Accidental spillage does not present a fire hazard and personnel can work very comfortably in close proximity. Together, these features allow material to be heated at point of use, eliminating the transport of hot drums. Speed By using the entire drum wall to input energy, the fastest practical heating rate can be achieved without product degradation. Heating times will depend on the contents of the drum, but to give a rough idea, the rate of temperature rise of a typical viscous organic liquid will be about 15 ºC per hour. The speed is further improved by the instant initial response of induction heating. Typically, Thermosafe has proved to be 2 to 4 times faster than ovens. Cleanliness With ingress protection to IP66, simple smooth surfaces and no moving parts, the induction heaters are ideal for use in clean environments. They can even be hosed down during use. Flexibility Single or Multi-drum "Oven" Applications In addition to being operated at point of use and integrated into the process, the heaters are used extensively as replacements for, and alternatives to, drum ovens. A key point to note is that far fewer individual heaters are required than the drum capacity of an oven. For example, one particular award winning installation of 3 Thermosafe units heats 20 drums per day. The ease at which capacity can be adjusted, to meet varying heating requirements of different materials, is in stark contrast to the fixed facility of an oven. Multi-Purpose The induction heater's unique features enable the same piece of equipment to be used in a wide range of applications to heat drums and a variety of other metal items, including gas bottles, small-scale reactors and process vessels. Complete access to the drum while heating enables pumps and stirrers to be employed. The drum and heater can be integrated into the system, often eliminating the first process vessel, and continuous feeding of material, at regulated temperatures and flow rates, can easily be achieved. Re-working and sampling of solidified or suspect material, even if heat sensitive, is a common task for Thermosafe. The lack of contact with the drum surface makes this possible even when the material is in its final packing. Uniform heating and instant response makes the heater ideal for removing residues from drums, significantly reducing wastage. With full drums, these same features enable very rapid removal of solid drum contents by melting the outer layer of material. Maintenance With no heating elements and no moving parts, the units have virtually unlimited life, and no maintenance is required.
