Koyuncu Ticaret A.Ş Koyuncu Ticaret Anonim Şirketi entered the sector in 1977 as an industrial gas producer and supplier. Focusing on welding gas mixtures in the 1990s, it served gas companies throughout Türkiye in a leading position in this field for many years...

We supply helium, argon, nitrogen, hydrogen, dry air, carbon dioxide, oxygen and similar gases in 5.0, 5.5 and 6.0 grade purity, in pressurized cylinders and liquid containers.

We fill these gases into cylinders and liquid cylinders at our Dilovası facilities and certify them in our laboratory. We can fill the gases we offer in various cylinder sizes, and we procure gases that cannot be filled in Türkiye from our main suppliers abroad.

In our ISO/IEC 17025 accredited laboratory, we fill and analyze calibration gases according to the requirements of customers who need traceable gases for emission measurement and environmental laboratories.

One of the most critical uses of gases in the food industry is creating a protective atmosphere inside the packaging to keep products fresh. Modified Atmosphere Packaging (MAP) is a method that has grown very rapidly in the food industry and continues to grow.

Industrial gases are obtained by separating atmospheric air and liquefying it using advanced methods. They play an important role in metal production, welding and cutting, automotive, food, electronics, glass, metallurgy and chemical industries.

At our Dilovası facility, we fill industrial gases with precision and supply them to our customers in cylinders, cylinder bundles, liquid cylinders or cryogenic tanks, according to their needs.
