We have proudly supplied world class temperature management solutions to our customers since we first opened our doors in 1940. Our primary focus at this time was manufacturing industrial freezers. The Cincinnati Sub-Zero brand quickly became synonymous with long-lasting, reliable, and high quality products.

From our humble beginnings, CSZ has grown from a supplier of industrial freezers to become a leading manufacturer of standard and custom environmental test chambers. These test chambers now include a wide variety of thermal, vibration, humidity, altitude solutions, and much more. Over time it became clear that the addition of a testing laboratory would not only provide more opportunities for growth but would allow us to provide a more complete portfolio of environmental testing solutions to our customers.

Throughout our more than 70 year journey to become one of the premier worldwide suppliers of environmental testing solutions we have held true to the philosophy that the customer comes first. This dedication to customer service has allowed us to work with leading manufacturers in over 22 industries including aviation, automotive, aerospace, defense, medical, energy, to name a few.

Located in Sharonville, Ohio, our campus is comprised of two buildings with over 150,000 square feet of manufacturing space. Each building has been tailored to provide flexibility, comfort, and safety for our employees while providing room for continued growth and innovation. Our testing facilities consist of two locations with one being on the main campus in Sharonville, OH and a second laboratory in Sterling Heights, MI.
