The elements are specially shaped so as to obtain the best curtain type exchange surface and are fixed on a stainless steel or steel plate. Fitted with an electrical connection box separate from the plate for uses at temperatures over 120 °C, the batteries may be powered by three-phase supplies up to 750 V.
The heating elements are wired with high temperature cables, generally in busbars mounted on insulators at one or more rates.
Designed to be used at temperatures up to 850 °C, the plates may be mounted on steel or stainless casings to allow their installation on the duct network
Devices can be produced according to ATEX directives.
