MACH® Aluminum Condensing Boiler

with 10:1 Mechanical Turndown Capability


MACH® Models C750, C900, C1050, C1500, C2000

Providing high turndown without sacrificing efficiency or reliability.

Patterson-Kelley continues to push the limits of technology by increasing turndown, with emphasis on system efficiency, reliability, and serviceability. By using a mechanical method to achieve higher turndown, we eliminate the need to add excess air. Adding excess air can reduce the dewpoint of the flue gas and adversely affect efficiency. The MACH® condensing boiler is now available with 10:1 mechanical turndown capabilities for natural gas models C750, C900, C1050, C1500 & C2000; perfect for a variety of applications.
