What Zeeco does

Zeeco, founded in 1979 and headquartered in Tulsa/Broken Arrow, Oklahoma, designs, engineers, manufactures, and installs industrial combustion and pollution control equipment for refining, petrochemical, LNG, power, pharmaceutical, and biogas customers worldwide. Core products include industrial burners, flare systems (enclosed, elevated, multipoint ground, and smokeless high-pressure air-assist designs), thermal oxidizers, vapor control systems, combustion electronics, process heaters, and rental equipment, supported by patented technologies such as the FREE JET ultra-low NOx burner, GLSF min-emissions burner, FlareGuardian VISR-based flare monitor, VerifEye fiber optic pilot monitor, and HPAAS smokeless flaring developed with Saudi Aramco. Zeeco operates seven in-house manufacturing facilities across the United States, United Kingdom, India, China, South Korea, Saudi Arabia, and Mexico, three global test facilities including the world's largest combustion research and test facility on a 250-acre campus with 17 full-scale test furnaces, and conducts research in ammonia combustion, computational fluid dynamics, and physical airflow modeling.

The company generates revenue primarily through custom, quote-based, project-based sales of engineered equipment, complemented by aftermarket parts and global field services for both Zeeco and third-party equipment, plus a usage-based rental equipment stream for turnarounds and emergencies. Go-to-market is direct enterprise field sales supported by technical papers, case studies, video content, and industry events, executed across 30+ locations in 40+ countries, with over 10,000 projects delivered annually and 3,000+ employees globally. Recent strategic activity has been aggressive on the inorganic side, with three completed acquisitions between late 2025 and May 2026: Devco Process Heaters (midstream O&G process heaters), Applicot Corporation (Japan market entry), and Oil & Gas Technologies (Australia and Asia-Pacific vapor control). Zeeco is a privately held, family-influenced company led by President and CEO Darton Zink, with no disclosed external institutional ownership.

Direct peers

• John Zink Hamworthy Combustion: John Zink (part of Koch Engineered Solutions) is the most direct global competitor to Zeeco, manufacturing industrial burners, flare systems, thermal oxidizers, and vapor control equipment for refining, petrochemical, and power customers. Overlapping product portfolio, customer base, and engineering-driven GTM make it the closest apples-to-apples peer.
• Callidus Technologies: Callidus (Babcock & Wilcox) designs and manufactures flare systems, thermal oxidizers, and combustion equipment for refineries, petrochemical plants, and gas processing — directly overlapping with Zeeco's flare and thermal oxidizer lines.
• Eclipse Combustion: Eclipse designs and manufactures industrial burners and combustion systems for process heating applications across refining, chemical, and OEM customers — a direct peer in industrial burner technology.
• Maxon: Maxon produces industrial combustion equipment including burners, valves, and shut-off systems for process heaters, with comparable end markets in chemicals, refining, and OEM process equipment — directly comparable in product line and customer profile.
• Aereon: Aereon specializes in flare systems, vapor control, and combustion products for oil & gas production and processing — overlapping with Zeeco's flare and vapor control product lines for upstream and midstream customers.

Broad incumbents

• Honeywell UOP: Honeywell UOP supplies process technology, catalysts, and combustion/emissions equipment to refineries and petrochemical plants globally. While broader in scope than Zeeco, it competes on burner systems, emissions control, and hydrogen/energy-transition process packages for the same customer base.
• Cleaver-Brooks: Cleaver-Brooks manufactures commercial and industrial boilers, burners, and related combustion equipment, serving overlapping end markets (refining, petrochemical, institutional, power). Comparable in scale and channel but with a more standardized product portfolio versus Zeeco's custom-engineered approach.
• Dürr AG: Dürr's environmental technology and industrial process equipment portfolios include combustion and emissions control solutions for industrial customers, making it a broader incumbent competing for similar emissions-compliance and process-heat projects.

Regional players

• Forbes Marshall: Forbes Marshall is a leading Indian manufacturer of industrial combustion, steam, and process control solutions, competing with Zeeco in the South Asian market and offering comparable burner and boiler products to refining and chemical customers.

Emerging players

• ClearSign Technologies: ClearSign is an emerging low-NOx burner specialist that uses Zeeco's test facility for development and Zeeco's manufacturing for deployment. Its Core ultra-low-NOx technology competes directly with Zeeco's FREE JET in refinery and process heater retrofits, making it a relevant emerging specialist peer.
