## The History of EG&G Rotron

Rotron was founded in 1946 and quickly became a pioneer in the design of precision cooling fans. During the 1950s and 1960s, the company developed innovative axial fan technologies and supplied cooling systems for military, aerospace, and industrial applications.

One of Rotron’s most significant engineering achievements was its patented inside-out motor design, which improved airflow, reliability, and cooling efficiency. Rotron products soon became the standard for military electronic cooling and were incorporated into numerous defense programs.

In the late 1970s, Rotron was acquired by EG&G, a leading defense contractor and technology company. Operating as **EG&G Rotron**, the company expanded its product line and continued supplying cooling solutions for military, aerospace, telecommunications, and industrial customers throughout the world.

In 1998, the company became part of AMETEK and continues today as AMETEK Rotron, preserving the engineering heritage that made the Rotron name famous.
