This Electric Heat Module has been designed so that there is easy access to either side of the electric coil. Over sized doors offer plenty of room to clean and maintain the electric coil from either side of the housing. The modular design lends itself to an easier installation since modules bolt together on the jobsite location. Electric heater modules are used for tempering make-up air for installations requiring frequent air changes. The units are rated up to 257KW with voltages and phases to meet all electrical requirements. Air volume range is 400 - 22,000 CFM up to 3" wg @ standard air density, depending on heating requirements. The heaters are intended for indoor or outdoor installations in commercial kitchens, factories, foundries and similar commercial and industrial occupancies.
