Corporate history and trade names
Our activities were previously carried out under the trade names 5A Mühendislik and 5A Mühendislik – Önder Çeri. Project, analysis and quality documents issued under these names form the archive of the engineering activities led by our founder, Önder Çeri. Today, this work continues through Önder Çeri Mühendislik Ticaret Limited Şirketi under the Ceri Mühendislik brand.
International distribution experience: 1994–2020
From 1994 to 2020, we served as the Turkish distributor for blower products initially branded Siemens and later Elmo Rietschle. Our responsibilities covered sales, repair and maintenance. This is part of our historical experience; the representation ended in 2020.
Technical service and maintenance experience
We combine the sales, repair and maintenance experience gained during our distribution activities with equipment selection, installation and control system work at treatment plants. We define the scope of each project according to the facility’s requirements and technical conditions.

Working with manufacturers
We do not currently represent a pump manufacturer. We seek project-based partnerships with wastewater pump manufacturers through direct sourcing. Our target markets are Türkiye, the Balkans, the Middle East and the Turkic republics. Investment in technical service, testing and repair facilities can be considered according to the needs of a partnership.
