S.T. Johnson Company

What S.T. Johnson Company does

S.T. Johnson Company is a privately held, family-owned industrial burner manufacturer founded in 1903 and headquartered in Fresno, California. The company designs, manufactures, and sells combustion equipment for industrial and commercial heating applications across the United States, with a direct sales model and no disclosed international operations.

The company's product portfolio comprises two main lines. The NOXmatic Series (NM-V venturi, NM-A axial-flow, NM-RF remote fan) covers 40-1,500 HP with ultra-low NOx emissions as low as 5 ppm, targeting facilities facing stringent emissions regulations. The FD68 Series (FD68 standard, FD68-LN low-emissions, FD68-RF remote fan) covers 50-2,000 HP with emissions from uncontrolled to sub-30 ppm NOx. Both lines share a cylindrical windbox architecture, axial counter-flow anti-flashback design, heavy-duty 1/4-inch flanges and 3/16-inch rolled steel construction, and CFD-optimized gas injection for uniform air-fuel mixing. Several models offer dual-fuel capability (natural gas plus #2-6 oil) for emergency backup. The company has cumulatively sold close to 300,000 units since founding.

Revenue is generated through three streams: industrial burner hardware sales (gas, oil, low-NOx, and ultra-low NOx models), replacement parts (fan wheels, oil nozzles, refractory tiles, ignition components, control panel parts), and technical support services. The go-to-market is direct sales-led across the United States via the company website, phone lines (including a dedicated FD68 line), and sales inquiry forms. Pricing is not publicly disclosed; customers request quotes from sales representatives. The company employs 11-50 people and maintains no disclosed institutional investors, parent company, subsidiaries, or M&A activity.

Core offering

S.T. Johnson Company manufactures and sells industrial and commercial combustion burners under two main product lines: the NOXmatic Series (ultra low-NOx burners, 40-1,500 HP, with NOx emissions as low as 5 ppm) and the FD68 Series (heavy-duty axial-flow packaged burners, 50-2,000 HP). The company also provides original replacement parts and technical support services for its installed base of nearly 300,000 units sold since 1903.

Product overview

S.T. Johnson Company offers two main burner product lines: the NOXmatic Series (ultra low-NOx burners) and the FD68 Series (heavy-duty axial-flow packaged burners). The NOXmatic Series includes three models (NM-V venturi, NM-A axial-flow, NM-RF remote fan) ranging from 40-1,500 HP with NOx emissions as low as 5 ppm. The FD68 Series includes standard, LN (low emissions), and RF (remote fan) models ranging from 50-2,000 HP with emissions options from uncontrolled to sub 30 ppm. Both series share common design features including heavy-duty steel construction, cylindrical windbox/housing, axial flow design for sound attenuation, and dual-fuel capability for emergency backup. The company has sold close to 300,000 units since 1903.
