About Us
With deep manufacturing expertise, DNL Mühendislik delivers industrial engineering solutions from Dilovası to the world.
DNL Engineering is built on the 27-year manufacturing and engineering legacy of Mervem Çelik Makina, founded in 1998 in Dilovası, Kocaeli. Focused on the iron and steel sector, Mervem Çelik specialised in EAF components and water-cooled equipment manufacturing for domestic steel producers.
Over the years, the company deepened its expertise in EAF upper shell and roof manufacturing, water-cooled steel and copper panel technology, dedusting systems and welding engineering, expanding its production facility in Dilovası to a total area of 2,000 m² (1,000 m² enclosed + 1,000 m² open). The facility is equipped with crane capacity of up to 40 tonnes and today operates with a 30-person engineering and production team.
In 2019, DNL Mühendislik Limited Şirketi was established to serve the international market with the same engineering team and production facility. To date, the company has delivered 47 projects across 12 countries: Turkey, Romania, Bulgaria, France, North Macedonia, Estonia, Finland, the United Arab Emirates, Saudi Arabia, Iraq, Egypt and Libya.
