Modulating Electric Heater(FE)

The Modulating Electric Heater is used for tempering make-up air for installation requiring frequent air changes. These modular units are rated up to 257KW with voltages and phases to meet all electrical requirements. Air volume range is 800 – 22,000 CFM and up to 3" wg at standard air density, depending on the heating requirements. These heaters are intended for indoor and outdoor installations in commercial kitchens, factories, foundries and similar commercial and industrial occupancies. Combination packages that include both the exhaust and the supply fans mounted on a single roof curb are also available. Contact your local sales representative for more information.
