HEAT EXCHANGERS SINCE 1903

HOW IT WORKS

The Officine Varisco heat exchangers

The tube heat exchangers of Officine Varisco are safe to use, easy to maintains, and they are mainly employed in the civil and industrial heating systems and in the process plants of thermal power stations and in district heating.

The heat exchangers are appreciated by the clients for their high performances, their efficiency over time and the interchangeability of all the components that Officine Varisco guarantees for 10 years.

The heat exchangers are designed and manufactured with the best materials, and they are built and tested according to the directive 2014/68 EU of the European Parliament for pressure equipment, ASME section VII div.1.

The structural design is achieved by calculation software or with the help of important research center’s programs, such as HTRI (USA).
