"S-engineering" is the official partner of the Department "Digital Factory & Process Drives" and "Automation and buildings safety" of subsidiary enterprise "Siemens Ukraine" in the status of Siemens Solution Partner Automation.

Our company is the Technology Partner of SIEMENS on the technology SIVACON S8 and SIVACON 8PT and was the FIRST and the ONLY one in Ukraine received a license to use WITHDRAWABLE (1/2, 1/4). The work of our company complies with all quality standards set down by the concern SIEMENS AG.

Quality and precision of product global technical requirements become tougher. This leads to the increase of technological equipment at production. Less space remains for engineering systems, including power supply and technological processes control systems.

SIEMENS keeps pace with the time and with the development of technological processes and creates new technologies. SIEMENS technology SIVACON S8 complies with strict requirements to minimize the occupied space, which is achieved not only by using the quick roll-out modules with load feeders, but also by their size.

Earlier, such withdrawable assembly occupied the entire width of the box but now it can take half (1/2 module) and even quarter (1/4 module) of the box. Thus, clients receive module system, quick feeder replacement and also a system that occupies four times less space that analogue systems.

“S-Engineering” is a Technology Partner of Siemens in technology SIVACON


Our company is the first and only in Ukraine that has license for the use of withdrawable units of reduced size and ready to provide clients with solutions for power supply and technological processes control systems, which meets the strict safety requirements, quick replacement and obviously - minimization of occupied space.
