Since mid-2010 we upgraded the shutter driving system. The shutter moves on six
large rolls and is driven by three-phase motor with the power of 120W and the
proper cogwheel. The mechanism works very smoothly and quietly. Most importantly
it is very reliable - during the tests we performed more than 1,500 open-close
cycles. After that the drive did not require any adjustment. This corresponds to
about 5 years of trouble-free activity.
The drive has been designed so that it was possible to upgrade its
previous version to the new one.
