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 neutral and thus very 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.
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.
heat transfer and thermal calculations are always carried out in
order to determine the heat transfer profile including max. surface
temperatures on the elements and to simulate extreme conditions.
This ensures optimum design and surface load, and eliminate the risk
burning-off the electrical heating elements.
