During 2010, Alfa Laval has been celebrating a milestone: its 125th anniversary of doing business in the United States.

The De Laval Separator Co. was established in the United States in 1885, and a factory was built in Poughkeepsie, N.Y., to manufacture the company's separators. Sales skyrocketed by the early 1900s. Soon, the De Laval name became iconic in farming communities across America, and the separator was as common on farms as the cows. The Poughkeepsie factory remained operational until 1990.

The company persevered through times of prosperity, depression and wars, and continued to grow, with the addition of heat transfer technology in the 1930s. It entranced the industrial separation market during World War II when it helped the U.S. Navy overcome a shortage of lubricating oil by developing oil separators. De Laval Separator Co. became an important supplier to the U.S. Navy and is still a well-known name in the marine industry.

Fluid-handling technology became part of the product portfolio during the 1960s, securing Alfa Laval's third key technology in the United States. In the mid 1980s, the company acquired Tri-Clover, the leading supplier to the sanitary fluid-handling industry. Other Alfa Laval brands include Sharples, Contherm, Packniox, Toftejorg, Merco, Standard Refrigeration and Champ.
