What Dyno One does
Dyno One Inc. is a privately held U.S. manufacturer and engineering services provider specializing in custom dynamometer and test cell systems, founded in 1983 and headquartered in Edinburgh, Indiana, with a second engineering facility in Owosso, Michigan. The company designs, manufactures, and assembles a portfolio of branded dynamometer products (AccuDyne AC dynamometers from 5 kW to 20 MW, MicroDyne units up to 6 kW, AccuBrake brake-based systems, HEViDyne EV/hybrid powertrain test systems, and AccuHD hub dynamometers), all orchestrated by the proprietary DynoLAB 4.6 Test Automation Controller that supports industrial protocols including MIL-STD-1553 for aerospace applications. Its systems deliver high-accuracy torque measurement (0.05% full scale), regenerative power recapture of up to 90%, and 24/7 unattended operation for performance, durability, and quality control testing.
The company serves a blue-chip enterprise customer base across automotive (Tesla, BorgWarner, Cummins, Visteon, Magna), aerospace and defense (Lockheed Martin Space, Sierra Nevada Corporation's Dream Chaser, Marotta Controls for the F-35), heavy equipment (Caterpillar, Achates Power), and certification (TÜV SÜD). Its go-to-market is a 7-step consultative enterprise sales process that delivers custom engineered systems with no off-the-shelf or self-service purchasing option. Revenue is generated across five streams: new dynamometer and test system sales, engineering services (mechanical, electrical, FEA, commissioning), repair and remanufacturing of legacy dynos from brands such as GE, Eaton, Horiba, and AVL, service parts, and on-site services including laser alignment, balancing, and predictive maintenance monitoring. Pricing is fully project-based with no public list prices. The company appears to be self-funded and independently owned, with no disclosed institutional investment or M&A activity beyond the asset acquisition of Sakor Technologies, which now operates as its Test Solutions and Engineering Division.
