Zudek was established in 1990 on the strength of its technical experience of the two founding partners, Alessandro and Alfredo Zudek, and a group of collaborators from the industrial context of Trieste, where the first ammonia refrigeration plants in the world were designed and constructed. In 1994 after several years of designing and producing refrigeration plants, Zudek manufactured the first low-charge ammonia chiller with frequency converter, able to meet the technical and maintenance needs of industrial production. All units are conceived and manufactured with maximum attention towards details and efficiency.
