After extensive training abroad, our team members developed and participated in the implementation and commissioning of the vacuum network in 1998. Since then, the same team, but in an expanded form, has been working until now. The experience we have gained allows us to constantly modernise and improve our technology. The systems we are currently implementing are significantly different from the first network built in 1998. Continuous technological progress leads to improved solutions aimed at increasing the reliability of the network and facilitating many operational improvements.
