“I work to satisfy my study and research need. Research is about knowledge and curiosity. This means dealing with others, communicating, finding new directions” Alessandro Zudek Zudek is a constantly evolving company. Since 1990, when it started with civil, industrial and naval installations maintenance, it never stopped. Research is its flagship. “I work to satisfy my study and research need. Research is about knowledge and curiosity. This means dealing with others, communicating, finding new directions”, says Alessandro Zudek. Zudek added, each and every year, a new element to its growth,...

punti di forza Strengths Some years ago, Carrefour opened a new structure near Paris. It was a big supermarket with at least 40 cash registers. They decided to use, for this new store, the best cold technologies for food preservation. After an accurate research on the industrial refrigeration market all over Europe, they chose Zudek. 2 Why? Because we use ammonia and we are ecologically compatible with their needs. Because our machines use little electric power and are highly performing. Because our machines maintenance is easy and remotemanageable. But, primarily, because we built a...

Water condensed Developed in 1994 for a customer, Illycaffè, that was tired of unreliable and poor chillers. Zudek, at those times, was engaged in maintenance. The challenge was to create a chiller, able to solve every reliability, cost management and sustainability problem. Mono-compressor water condensed chiller up to 3000kW Thanks to the inverter, flooded evaporator and PLC integrated management, varimatik® is constantly evaluating and adapting to all load requests. Today we have more than 120 chillers of this kind installed in different countries. Compact size In relation to the...
