Tulsa Heaters

What Tulsa Heaters does

Tulsa Heaters Inc. (THI) is a privately held industrial equipment manufacturer founded in 1985 and headquartered in Tulsa, Oklahoma. The company designs and manufactures custom-engineered fired heaters, waste heat recovery units (WHRUs), and complementary process systems primarily for the oil & gas, petrochemical, and offshore energy industries. Its units are deployed in refineries, gas processing plants, petrochemical facilities, and offshore platforms, with active or completed projects spanning more than 30 countries.

The firm's technical core is a proprietary engineering software library refined over more than three decades, including a Two-Phase Process Fluid Program, a Thermal Cracking/Coking Program, and mechanical design tools. Combined with deep process domain expertise (350+ years of combined engineering experience across staff), this library underpins the design of custom units — including once-through and natural draft process heaters, vertical cylindrical and cabin (box) heaters, waste heat recovery coils and systems, and complementary offerings such as NOx reduction systems, SCR/SNCR units, and air preheat systems. The company also performs retrofit and revamp work on virtually every major US heater brand, providing an installed-base service line independent of new-unit sales.

Tulsa Heaters operates on a project-based, quote-driven commercial model: each heater is custom engineered to client specifications and sold through direct technical engagement. Disclosed manufacturing capacity is $70MM per year for new equipment and $15MM per year for revamp work, supported by 40+ direct employees and 200-300 indirect personnel. The customer base is concentrated in US integrated oil & gas and refining majors, including BP, Chevron, Phillips 66, ExxonMobil, Shell, and Valero. The firm holds ISO 9001:2015 certification and conforms to API Standard 560, and operates an annual Heater School technical education program.
