75+ Years of Consolidated Sterilizer Systems

Founded in 1946 by William A. Barnstead Sr., Consolidated Sterilizer Systems was originally known as Consolidated Machine Corporation. During inception, Consolidated’s initial contracts were with the U.S. Department of Defense and focused on the production of rolling door autoclaves and water stills. This work, along with other notable contracts, helped Consolidated quickly build a strong and lasting reputation as an innovator and a technical resource for difficult engineering issues within its fields of expertise.

Today, over 75 years later, Consolidated’s heritage for manufacturing excellence continues, thriving alongside the company’s steadfast commitment to deliver high quality, high performance sterilization solutions. For these reasons, CSS continues to be recognized as an industry leader and one of the most reliable sterilizer manufacturers in the world.
