According to The Gas Review, about 50km east of Jakarta in West Java by highway lies the Karawang International Industrial City, where many Japanese automobile manufacturers and other companies have a presence, including IIG Indonesia, the local subsidiary of Iwatani.

Here, IIG Indonesia has a comprehensive filling facility for oxygen (O2), nitrogen (N2), argon (Ar), carbon dioxide (CO2) and mixed gases, along with a 4,000 Nm3/h air separation unit (ASU) that was installed in 2016. This ASU plant entered full-scale operation in October last year and continues to operate smoothly.

Iwatani established IIG Indonesia in 1996. A filling facility was opened in the following year and since then, the Iwatani Group has created a ‘one-stop’ service system for all industrial gas business starting with the sale of all types of industrial gases, machinery, and welding supplies and later expanding to engineering, maintenance, distribution and inspection facilities.

Now the ASU has achieved stable operation, IIG Indonesia’s President, Hidekazu Sofue, gives the stable supply of liquefied CO2 as the next topic. Liquefied CO2 is obtained from local companies in the industry for resale, but to stablise stocks, a new 100 tonne storage take is to be installed.

For liquid supply, two eight tonne mini tanker trucks have been added for O2 and N2. In Indonesia, microbulk supply using one to three tonne mini storage tanks is becoming popular in place of LGCs. Transportation efficiency is being increased with tanker trucks that have a smaller turning radius.
