Siemens Authorised Maintenance and Service · Trimbox Authorised Distributor for Turkey
Founded in 2021. With a team of 42 we design, supply, install and maintain — across Turkey, under one contract.
We hold an authorisation for five brands: Official Siemens Dealer and Authorised Maintenance and Service for Siemens; Authorised Distributor for Turkey for Trimbox; Authorised Dealer for Rotarex, Gorgy Time and Adder. That means we do not have to fit the system in your specification into one brand's product line: we choose the right product for the application.
Scope splits into four, and we deliver whichever one you need:
To take a leading position in the sector with advanced technologies, and to keep customer satisfaction at its highest through sustainable and innovative solutions.
To make a difference in the sector by delivering the most suitable solutions, technically and cost-wise, with an approach focused on transparency and quality.
The documents a supplier approval or a tender file asks for: our management system certificates and our brand authorisations; with number, scope and validity date.
Our quality, environmental and occupational health and safety management system certificates. The details are given as printed on the documents.
