Description

The Multi-Pass Commercial Boiler (MPC) is loaded with innovative features that are unsurpassed by any other boiler in the industry. Take a close look at the MPC, and there is no question that it is setting the new standard for USA-made commercial cast iron boilers. Multi-pass boilers operate differently than more conventional single or double-pass boilers. A multi-pass boiler, such as the MPC, directs flue gases through multiple combustion chamber passes, extracting the maximum amount of heat out of the hot boiler flue gases. With single or double-pass boilers, the burner fires into a combustion chamber, then the hot flue gases pass upward between the sections (usually through a pinned or baffled flueway) and out into the venting. The MPC directs flue gases into several smaller passes, which allows the sections to absorb more heat than if the flue gases just passed through the boiler sections one time. The MPC is also available with Burnham Commercial’s newest control, the SBC™ control, which provides complete boiler control capability at the fraction of the price of a comparable system. The SBC control is a combination operating and staging control that will control up to 8 fully modulating boilers and is available as a factory-wired package installed in any Power Flame, full mod burner, with an RM7897A or better Honeywell flame safeguard. The SBC control can save money by reducing installation time and reducing the number of controls required to control your boiler. The SBC control also saves money by firing the boiler(s) at the precise rate of modulation to meet the building load while limiting short-cycling.
