What Combustion Systems does
Combustion Systems Co., Inc. is a privately held Indianapolis-based industrial equipment and services firm founded in 1974, operating under the Combustion Systems brand alongside two wholly-owned subsidiaries, Conveying Systems Inc. and Contracting Services Inc. The company designs, sells, installs, services, and integrates boiler, burner, and combustion-control systems for industrial, commercial, and institutional customers, with an installed base spanning watertube, firetube, firebox, condensing, commercial vertical, and waste-heat-recovery boilers from manufacturers including Johnston, Burnham, and Cannon Boiler Works, paired with burners from Weishaupt and Todd Combustion.
The company's product platform centers on three pillars: (1) proprietary emission-control technology led by the Emission Rx Thermal Oxidizer, (2) controls and instrumentation built on third-party industrial platforms (Allen-Bradley PLC/HMI, Bailey, Honeywell UDC) combined with proprietary efficiency systems including The Boiler Consultant (TBC) real-time performance monitoring platform and EzTrim linkageless O2 & CO trim control, and (3) custom Data Acquisition and Distributive Control Systems for boiler overview, trends, and surge tank monitoring. Supporting capabilities include an in-house fabrication shop with shearing, forming, rolling, welding (Arc, Mig, Tig, Heliarc), and machining equipment that enables custom steel fabrication, conveying systems, bucket elevators, and material handling solutions sold through the Conveying Systems subsidiary.
The business model combines one-time capital-equipment sales with recurring professional services revenue across Class I-VIII service classifications covering troubleshooting, tuning, CAD/3D modeling, emissions testing, water analysis, and long-term planning. Go-to-market is sales-led via direct field sales as a manufacturer's representative, supplemented by a digital presence (website, LinkedIn, Facebook, X). Customers are concentrated in Midwest US with documented projects extending to Pennsylvania and other states, serving breweries, universities, food manufacturers, grain handlers, and industrial manufacturers. The company employs 11-50 people, has no disclosed institutional funding, and operates with no parent company or recent M&A activity.

Combustion Systems competitors and assessment
Company assessmentDirect peers
- Burnham Holdings: Parent of multiple boiler brands (Burnham, Weil-McLain, US Boiler) selling hydronic and steam heating equipment to commercial/institutional accounts. Comparable product portfolio and end markets to CSI.
- Cleaver-Brooks: One of the largest North American manufacturers of industrial boilers and burners, offering equipment sales, service, and parts. Directly comparable to Combustion Systems as a full-line boiler/burner OEM with integrated controls and aftermarket services.
- Hurst Boiler & Welding Co. Manufacturer of biomass, gas, and oil-fired boilers plus related heat-recovery equipment. Overlaps with CSI on industrial steam systems and turn-key combustion packages.
- Weishaupt: Global manufacturer of burners and combustion systems, resold and supported by CSI. Direct peer in the burner and combustion-management category with overlapping industrial accounts.
- Johnston Boiler Company: Manufacturer of firetube boilers used in industrial and commercial applications. CSI resells/retrofits Johnston boilers, making Johnston a peer in the same product category with overlapping customer base.
- Superior Boiler Works: Manufactures industrial firetube and watertube boilers with accompanying service and parts offerings. Comparable scope, customer type, and channel mix to CSI's industrial boiler business.
- Fulton Companies: Manufacturer of steam boilers, hydronic boilers, and thermal fluid systems with a wide industrial/commercial channel. Compare to CSI on boiler manufacturing, controls integration, and aftermarket service model.
Broad incumbents
- Honeywell (Combustion Controls): Industrial combustion controls and instrumentation (e.g., UDC series) that CSI integrates alongside its own TBC/EzTrim systems. Broad incumbent shaping the standards CSI must interoperate with.
- Emerson (Combustion/Boiler Controls): Provides industrial automation, burner management, and combustion control solutions. Comparable as a controls and instrumentation incumbent whose products compete with or complement CSI's TBC/EzTrim offerings.
Emerging players
- Todd Combustion: Specialty burner manufacturer (including combination gas burners) used in CSI retrofits. Comparator as a specialty combustion equipment supplier targeting similar industrial customers.
