AM Series Boilers
Brand: AERCOThe AM Series of commercial condensing boilers are essentially pre-packaged boiler plants giving you the reliability and redundancy of a multi-unit system in a single unit.
Each unit consists of between two and four individual modules, each with its own combustion chamber, burner, gas valve, and combustion controls and safeguards, all tied together to common water connections and assembled in a single enclosure.
This provides all the advantages of a larger boiler plant, including high turndown and multiple-unit redundancy, while still keeping installation costs down and operation simple.
Full front access means near-zero side clearance with no loss of serviceability when more than one million BTUs are necessary. Installations take up minimal space and remain simple to service.
Standard Modbus controls easily connect to Energy Management or Building Automation System.
The high efficiency of the AM series condensing boilers means less wasted heat and lower operating costs. In a condensing unit, lower fire rates return higher operating efficiencies.
By running multiple modules at low fire rather than one large unit at higher fire, the AM series ensures the installation is always running at its most efficient.
High efficiencies also mean lower flue temperatures and thus a range of venting options. All units can be vented in polypropylene, PVC, cPVC, or AL-294C vent materials. Available in 399, 500, 750 and 1000 MBH.
