MFC (Multi-Fuel Condensing)

AERCO's MFC (Multi-Fuel Condensing) hydronic boiler is capable of firing with multiple fuels including natural gas, propane or #2 fuel oil. It features a proven 4-pass fire tube heat exchanger design for maximum heat transfer and efficiency and is designed for condensing application in any closed loop hydronic system. The heat exchanger’s combination of high quality carbon steel/316Ti stainless steel construction ensures the highest degree of durability. The 316Ti SS construction in the heat exchanger’s 4th pass offers superior corrosion resistance against acidic flue gas condensation. Likewise, it can be fired with multiple fuels including natural gas, propane or #2 fuel oil (as backup), offering dual fuel flexibility. Moreover, the MFC series features dual return connections standard for optimal application flexibility and seasonal efficiency gains of up to 12%. The heat exchanger’s maximum working temperature of 240°F allows for greater operating temperature range and meet the requirements of higher temperature applications when necessary, but allows for the building to reset water temperature for condensing in the shoulder months.

The MFC Series is fitted with industry leading power burners whose emissions will meet most stringent NOx and CO requirements. The fully modulating burner also maintains AERCO standards for energy efficiency, longevity, reliability and construction quality.

The MFC Series boilers can be used as an individual unit or in modular arrangements and offers selectable modes of operation. In addition to controlling the boiler according to a constant set point, indoor/outdoor reset schedule or 0-10V signal, one or more units can be integrated via Modbus communications protocol. For boiler plants ranging from 2 or more boilers, an available sequencing controller designed to optimize plant efficiency provides the right solution. Likewise, MFC systems can be easily integrated with a facility-wide Energy Management or Building Automation System.
