Cincinnati Sub-Zero


In 1940, Cincinnati Sub-Zero (CSZ) Products, Inc. opened for business as a distributor of frozen foods that would later become the first U.S. distributor of home deep-freezers. Nine years after its start, the company changed directions and began manufacturing and marketing temperature-controlled products. Today, CSZ is the customer-focused manufacturer of patient body, blood and fluid temperature control products for the healthcare market along with industrial environmental simulation testing equipment and contract testing services for multiple industries.
