Following the acquisition by Bruno Presezzi S.p.A, a Brianza-based company that successfully revitalized the troubled history of Franco Tosi Meccanica S.p.A., among other interventions aimed at increasing the productivity of the historic Legnano site, a renovation of the heating system in the production departments also became necessary.
The heating of the industrial site was provided by old boilers, with an installed thermal capacity of over 30 MW, connected to a system of hot water panels located in the upper parts of the buildings and on the walls.
This system, however, taking into account the considerable height of the buildings and the low degree of insulation, could not guarantee adequate comfort in the production areas. In addition to this, energy consumption was enormous.
First of all, it was important to find a solution that could be flexible: in the various departments located across the extensive production area, the activities carried out are different; it is therefore important to calibrate the installed power to ensure a good level of comfort within all departments.
Another client requirement was to quickly reach full system operation, in the areas where necessary, according to their specific needs.
