1.1 Million Sq Ft Amazon Logistics Center Roof Installed with Leister VARIMAT V2

The roof membrane of the new Amazon Logistics Center in Vercelli, Italy, was welded with a Leister VARIMAT V2 in July 2017 of last year.

Successful under time pressure and temperature fluctuations
108,000 square metres of roof area - as large as 15 football fields – is a considerable area, for a roof and for a VARIMAT V2. The project lasted from February to July 2017 and welding was made more difficult by temperature fluctuations. Temperature fluctuations were caused not only by the changing of the seasons from winter to spring to summer, but especially in the summer by the change from day to night. The VARIMAT V2's welding temperature had to be adjusted through-out the day to counteract changes in the outside temperature; this ensures high quality welding seams that will not leak. 

Be on the safe side with closed-loop technology from LEISTER
With the closed-loop technology from LEISTER you are on the safe side when it comes to the quality of the welding seam. Why? This technology guarantees that the parameters remain permanently constant even in the case of voltage fluctuations. In this way you always achieve consistent welds under different conditions on the construction site. ​
