Wenkel srl is a member of the Fiorini Industries Group and it is the owner of the Heizer and Sile brands that represent two historic Italian companies specialized in the construction of products for the thermotechnical market.

Heizer was born near Milan over fifty years ago and specialized in the specific segment of water heaters for industrial, gas and electric use.

Sile was founded in 1945 in Treviso and specialized in the production of gas boilers, stainless steel kettles and pressure equipment such as autoclaves for raising water, vertical expanders and steam and superheated water generators.

In January 2020, the union of the two companies gave birth to a new reality, young and dynamic, oriented to create cutting-edge technological products for the thermotechnical sector in a sustainable way, able to give a response to the energy transition in progress, reliable and performing.

In order to achieve these goals, major investments in the area of product innovation, human resources and production facilities have been made and are planned in the future.

The production is in fact concentrated in the production plant of Casier (TV) whose plants have been completely renovated with new production lines for the construction of tanks for the production of domestic hot water and pressure equipment (autoclaves, expanders, steam generators) according to the European Directive 2014/68/EU-PED for which the company has a specific technical competence.
