"Putting a Damper on Cold Air"

HMI HOYME Manufacturing Inc., since 1984, designs and manufactures unique energy efficient motorized air control dampers and devices for the commercial and residential heating and ventilation industries. Friendly to the environment plus meeting ventilation requirements, HMI HOYME dampers and accessories have proven to be well accepted by the HVAC industry across the United States and Canada. 

 
 The COMBUSTION FRESH AIR DAMPER, Series 'HOM' is motorized and used for the control of fresh air for combustion. It is patented and Code Certified to be field installed and interlocked with a thermostat of a furnace or aqua-stat of a boiler, using either oil, propane or natural gas. The damper is placed at the terminating end of an insulated fresh air inlet duct beside the furnace. When the thermostat asks for heat, this motorized damper opens to allow fresh air for complete combustion. When the furnace stops, the damper closes to prevent the entry of unnecessary cold air. This results in added comfort with a definite saving of fuel.




Another HMI HOYME damper is the Series 'HAC' AIR CONTROL DAMPER - These dampers are placed in-line and are used for FRESH AIR VENTILATION and ZONE AIR CONTROL. When used for ventilation, any exhaust fan turned on will open the fresh air damper and thus fresh air is brought in to replace air being exhausted. 

 

 HMI HOYME also manufactures a CSA certified Flue damper called a 'HAC-F' Flue Damper - These dampers are placed in-line and are designed to save energy by stopping the escape of warm air up the chimney vent while the heating appliance is not firing and is interlocked to be open during firing.  This damper is spring loaded and fails-safe-open in the event of power failure.

Check out our Interface Relay Adaptors page. These adaptors have a number of uses related to controling our fresh air dampers and interlocking with but not interfering with your existing HVAC system. They are also useful for zone air control, with a thermostat in each room it will open the damper for proper air flow to that room.
