| 1903 | A German immigrant named Raphael Herman establishes a company in Detroit for the manufacture of hand-operated boiler cleaning devices. This is the beginning of Diamond Power Specialty Company (DPSC). |
| 1922 | The Babcock & Wilcox Company (B&W) acquires controlling interest in DPSC. During the 1920s, the company develops a chrome-iron alloy element material and the first retractable sootblower to withstand ever-increasing boiler temperatures. |
| 1930-1939 | DPSC begins producing reliable, direct-reading water level gauges. The company also develops an automatic air puff sootblower which utilizes bursts of compressed air (rather than steam) for cleaning boiler tubes. This development proved particularly valuable to the U.S. Navy during World War II; not only did it conserve the fresh water used for shipboard boilers, but it emitted considerably less stack discharge during sootblowing operations aboard ship, helping to conceal the ship’s location. |
| 1940-1949 | DPSC introduces a positive action poppet valve which is still an important feature of our sootblower product line. A closed-circuit television system is developed by the company for remote reading of boiler water levels. |
| 1950-1959 | DPSC moves into new headquarters in Lancaster, Ohio, and continues to improve upon its sootblower designs to clean ever larger fossil fuel-fired boilers. |
| 1960-1969 | DPSC acquires Diamond Blower Ltd. of Southampton, England, which began a period of international diversification. It later relocated to Dumbarton, Scotland, and operates today as Diamond Power Specialty Ltd. |
| 1970-1979 | DPSC pioneers waterlancing technology as a means of cleaning high slagging, coal-fired boilers, and lengthens its long retractable sootblowers to accommodate increased boiler sizes, becoming the exclusive supplier of 56-foot travel units for 1300-megawatt utility boilers. |
| 1972 | DPSC becomes a wholly-owned B&W affiliate. |
| 1980-1989 | DPSC’s international operations are expanded into Australia, Finland, Korea and China. |
| 1997 | Diamond Power International Inc. (DPII) is formed to enhance the organization’s product and service offerings, and customer support. |
| 2000-2009 | DPII introduces the innovative Gemini sootblower nozzle which reduces steam consumption and increases cleaning energy. Setting a new standard for precision, reliability and water efficiency, DPII introduces the Hydrojet boiler cleaning system which can replace a complete furnace wall of sootblowers. A Swedish subsidiary of DPII acquires LT-Produkter Skutskär AB, an automatic port rodder cleaning company in Skutskär, Sweden. The acquisition reinforces DPII’s leadership position in the supply of boiler cleaning and diagnostic products for the pulp & paper recovery boiler market. DPII acquires Applied Synergistics Inc (ASI), a supplier of control systems for optimized boiler cleaning. DPII acquires total ownership of the Diamond Power Hubei Machine Company Ltd. (DPH), located in Jingshan, Hubei, China. |
| 2025 | B&W announced the sale of Diamond Power business to ANDRITZ Group, an international technology group headquartered in Austria. The Diamond Power team joined the ANDRITZ family, marking a strategic milestone for ANDRITZ’s Recovery and Power Boiler Service business. |
