MCAS Modulating Combustion Air Supply SystemTM
EXHAUSTO's MCAS Modulating Combustion Air Supply SystemTM, is for installation and use in mechanical rooms containing heating appliances, like boilers and water heaters, or commercial laundry dryers.
The purpose of the system is to provide an exactly measured amount of combustion air for the appliances and eliminate the use of gravity air louvers.
It can be used in conjunction with any type of combustion system, whether a boiler, furnace, commercial dryer, etc. that is gas or oil-fired.
The MCAS System maintains a perfect, constant mechanical room pressure during the combustion process by modulating the fan capacity. The system creates and maintains a preset room pressure prior to or immediately after the appliances start. It can also be set to run continuously.
The system monitors the mechanical room pressure condition all of the time, and has an integrated safety function. Should the room pressure fall more than 40% below the set point for more than 12 seconds, it deactivates the appliances to prevent a potentially hazardous situation.
Features:
° Variable speed & direct drive .
° Lower installation costs.
° Safer operation.
° Listed to UL 1995.
° 2-year factory warranty
