Qmark Marley Electric Ceiling Heater

Qmark CDF Series


Commercial Downflow Ceiling Heater Assembly Only 


Outstanding Performance In the Ceiling Or On It !!


Designed Specifically For Commercial and Industrial Applications

  • Type CDF ceiling-mounting fan-forced heaters are designed for commercial and industrial areas requiring electric fan-forced heat.  Capacities are 2,000 to 5,000 watts.  The optional type CDFSE surface enclosures are designed to mount flat on the ceiling and extend only six inches into the room. The optional type CDFRE enclosures have no protrusions outside the recess box, allowing the heater to recess only seven inches into ceiling space.  Mounts into permanent ceiling with trim ring.

  • Built-In Fan Delay - Space temperature is controlled by a wall or unit-mounted thermostat.  When the thermostat calls for heat, the heating elements and fan energize.  When the thermostat is satisfied, the elements shut off, but the fan continues to operate until all of the heated air is discharged.  This feature avoids exposing the heater to residual heat, thus achieving a high comfort level and longer component life.

  • Automatic Thermal Cutout - A thermal cutout shuts off the heater in the event of over-heating and reactivates the heater when the temperature returns to normal.

  • Multiple Phase Heaters - The 208 and 240 volt heaters can be field converted from single to three-phase operation. 277 volt single-phase heater is also available.

  • Multiple Wattage Heater Sections - The 5,000 watt heater can be field converted to 3,800 watts or 2,500 watts, and the 4,000 watt heater is convertible to 3,000 or 2,000 watts.

  • Thumb Pins align and temporarily hold the enclosure cover to the heating section freeing both hands to finish installation.

  • Please Note: Heater Enclosure (CDFSE/CDFRE) are sold separately
