Cincinnati Sub-Zero (CSZ) has supplied world-class temperature management solutions to its customers since they first opened its doors in 1940. Their primary focus at this time was manufacturing industrial freezers. The CSZ brand quickly became synonymous with long-lasting, reliable, and high-quality products.
From their humble beginnings, Cincinnati Sub-Zero has grown from a supplier of industrial freezers to become a leading manufacturer of standard and custom environmental test chambers. Cincinnati Sub-Zero 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 CSZ to provide a more complete portfolio of environmental testing solutions to our customers.
Throughout their journey to become one of the premier worldwide suppliers of environmental testing solutions, Cincinnati Sub-Zero has held to the philosophy that the customer comes first. This dedication to customer service has allowed them to work with leading manufacturers in over 22 industries including aviation, automotive, aerospace, defense, medical, energy, to name a few.
