DCA EDH series duct heaters will provide additional room heatingfor all DCA dehumidification systems. These heaters provide an economical source of either supplemental or primary room heating.

EDH series duct heaters are for direct mounting only on the discharge of the dehumidifier and not downstream in the dischargeductwork. They are shipped loose for field installation. A single high voltage source separate from the dehumidifier and a single low voltage connection are all that is required - allowing for easyinstallation.

Standard with every heater are air flow pressure switches, high limitcontrols and fuse blocks. The optional two-stage room thermostat ties in with the 24 volt circuitry of any DCA dehumidifier. DCA alsooffers a complete line of gas fired in-line duct furnaces when desired.

All DCA electric duct heaters carry a one year parts only warranty.
