Electric process air heating is normally quite fast established. In some countries even quite economical in operation (a.o. France, Sweden, Norway). Due to the increasing amount of electricity produced from wind power, solar cell and other new energy sources - electrical heating today becomes CO2 environmental. Advantages for using electrical heating include almost unlimited temperature rising, and it is therefore frequently used as additional boosting. On the other hand it requires faith in the manufacturer of the equipment, as burned-off electric elements are only a too well known problem to many users of electric heating. At AB&CO extensive calculations on heat transfer and surface temperatures of the heating elements, are always carried out in the actual task. This ensures optimum surface load and consequently that the elements does not burn off.
Often the heaters are installed under demanding and critical circumstances. Explosion proof electrical
heaters (ATEX) are used widely within petrochemical industry and other chemical
industries, as well as food industry e.g. production of powder.
