ErtelAlsop Revenue and Competitors

ErtelAlsop is the result of the merger of Ertel Engineering and Alsop Engineering. Ertel Engineering was founded by Frederick Ertel in 1932 in New York City. He originally manufactured and sold depth filter media for the pharmaceutical industry. In 1938, he moved his company to Kingston, New York, about 100 miles north of Manhattan, on the Hudson River. In Kingston, Ertel expanded the business to include plate and frame filter presses, pumps, agitators, bottle fillers, and other equipment for liquid processing. In 1943, Ertel developed the first pyrogen retentive filter media for Bristol Laboratories, to use in the manufacturing of penicillin for World War II. In 1979 Ertel patented the first enclosed horizontal plate and frame filter press in conjunction with Avon to eliminate vapors from Avon’s production floor in order to improve working conditions. As usual, Ertel was willing to go the extra mile to provide a solution for its customer’s application.
