DPSC begins producing reliable, direct-reading water level gauges. The company also develops an automatic air puff sootblower which utilized 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.

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.

DPSC moves into new headquarters in Lancaster, Ohio, and continues to improve upon its sootblower designs to clean ever larger fossil fuel-fired boilers.

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.

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 units.

DPSC’s international operations are expanded into Australia, Finland, Korea and China.
