A new heating network for the Ferney-Voltaire high school (01)

In 2017, the Ferney-Voltaire high school underwent a renovation of its heating network. Located in the Ain department, not far from Geneva, the 3-storey building accommodates around 2.600 students.

Built in the late 1950s, this school was heated from the start by electric heaters. In order to reduce energy consumption and improve student comfort, the Ferney-Voltaire town hall has decided to replace electric heating with a gas heating system. Carried out during the summer of 2017, these works cost 900.000 euros.

Two gas boilers and 400 radiators installed in 10 weeks

On this site, Viega's Megapress solution was chosen for its rapid and safe implementation. The installation was carried out by the Climsanit company (Bourg-en-Bresse), directed by Christophe Pujol, who installed this system for the first time. Founded in 1985, the Burgundy plumbing, heating and ventilation company now has 48 employees. Used to tertiary sites and collective housing, the installer chose the Viega crimping system for the high school's steel connection network. Instead of the existing electric heating, Christophe Pujol's teams installed two gas boilers of 500KW each and 400 radiators.

The cold crimping technique made it possible to make the connections safely, without flame and without additional cleaning after the work. Result: a clean and operational site as soon as it is filled with water. “Viega's Megapress crimping system gave us greater security during installation and considerable time savings. This last element was fundamental because we had a very tight schedule to carry out this work before the start of the school year in September 2017 ”notes Christophe Pujol.

The revolutionary cold crimping technique

Intended for use in heating, cooling and industrial installations, the Megapress system offers a real alternative to welding, threading or screwing. Cold crimping is faster, safer and above all more cost-effective due to the considerable time saved on site.

Like all Viega press fittings, Megapress fittings are fitted with the SC-Contur device which causes a forced leak in the case of non-crimped fittings. These connections are then immediately visible during a tightness check ?? and can be crimped later. Once the crimping is completed, the tube connections are permanently sealed.
