Indonesia's Refinery Development Master Plan aims to raise national crude processing capacity towards two million barrels a day, with the biggest existing refineries to be upgraded and new ones built at Tuban and Bontang. Crude processing, storage and marine loading create Zone 1 areas. A hazardous area mobile phone distributor in Dumai Refinery, Riau would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Dumai Refinery, Riau has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Fortune Indonesia reports the unit has been operating since 1971 and spans Dumai and Sungai Pakning, with products including LPG, jet fuel, diesel and green coke.
The Dumai refinery has operated since 1971, and the Putri Tujuh Dumai and Sungai Pakning refineries together have supplied fuel to Sumatra and contributed to regional development in Riau.
The refinery generates the power it needs from natural gas supplied by fields in South Sumatra and Jambi, including Grissik, Bentu and Jambi Merang, which cuts its fuel cost by about 40 percent.
Dumai is on the coast of Riau Province in Sumatra and supplies the island with gasoline, aviation fuel, diesel, kerosene and LPG, so it is a regional distribution hub as well as a processing site.
Dumai's crude capacity is quoted at between roughly 127,000 and 170,000 barrels a day depending on the source, which places it among Indonesia's larger refineries.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.

Dumai is Pertamina's Refinery Unit II and its Sungai Pakning site is managed with it. Contractors and equipment suppliers usually register through Pertamina vendor processes and the unit's own safety induction, so confirm current requirements with the refinery.
National plans to upgrade the biggest refineries mean new process areas and construction activity beside operating units. Contractors in new areas typically follow the project's hazardous-area drawings, so check the classification for your specific work front rather than assuming existing plant limits.
The unit covers Dumai and Sungai Pakning, and each site has its own areas and drawings. Rules for devices are set by Pertamina, but practical details may differ. Ask the operator for requirements covering both sites. Confirm with the site operator.
