Marshall C Series Packaged Boilers
The Marshall C Series is a robust, high-capacity packaged boiler designed for heavy industrial applications requiring 6 to 25 TPH of steam. Featuring a true three-pass wet back design, it prevents dangerous soot build-up, maintains low flue gas exit temperatures, and guarantees complete combustion. Equipped with advanced Electronic Compound Regulation (ECR) burner technology and a single-element level control system, the Marshall C seamlessly handles fluctuating plant loads while maximizing safety and fuel economy.

You can equip the boiler with the Forbes Marshall EffiMax System, an online efficiency monitoring system that continuously tracks direct and indirect efficiency, blowdown, and trim control to ensure optimal real-time performance.
It is built with high thermal inertia—meaning it features a high heat transfer area, high water hold-up, and ample steam space. This acts as a thermal flywheel to deliver dry steam without pressure drops during sudden plant load fluctuations.
The Marshall C offers an excellent burner turndown ratio of 1:3 to 1:5, depending on whether it is firing oil or gas.
