Cilacap Refinery, Central Java: projects and investment

As part of modernisation, Pertamina is improving management of more than 85,000 maintainable assets at RU IV, starting with a maintenance master data project to classify every item correctly.

Cilacap Refinery, Central Java: industry on the ground

The unit makes gasoline, diesel, kerosene, aviation fuel and LPG, and also asphalt and petrochemicals, so it combines liquid fuel, pressurised LPG and petrochemical hazardous areas in one complex.

Cilacap Refinery, Central Java: logistics and access

Indonesia remained a net importer of petroleum products in 2024, at about 787 thousand barrels a day or 42 percent of consumption, which keeps pressure on large refineries such as Cilacap to run reliably.

Cilacap Refinery, Central Java: geography and layout

Refinery Unit IV is in Central Java and plays a critical role in meeting domestic fuel and petrochemical needs for the island, which makes shutdowns carefully planned events.

The term · ATEX and IECEx

What “ATEX and IECEx” means for a smartphone

ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.

For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.

In Cilacap Refinery, Central Java. Reviewers at Cilacap, Indonesia's largest refinery, would expect certificate evidence that traces to the marking, with a schedule of conditions. The IS-04Z1 evidence is in progress. A dual ATEX and IECEx route helps because the refinery's maintenance and upgrade contractors often bring equipment records from international projects.

Questions · Cilacap Refinery

Frequently asked questions

Can we buy an ATEX and IECEx mobile phone in Cilacap Refinery today?

Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.

What does an ATEX and IECEx mobile phone in Cilacap Refinery cost?

SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.

Is the IS-04Z1 ATEX and IECEx certified?

Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.

Which areas at Cilacap Refinery, Central Java would use it?

Likely candidates are refinery process units, crude and product tank farms, marine loading facilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.

Is intrinsically safe the same as explosion proof?

Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.

What products at Cilacap create the main gas hazards?

The complex processes crude into gasoline, diesel, kerosene, aviation fuel and LPG, plus asphalt and petrochemicals. Flammable vapour from light products and pressurised LPG are the usual concerns, but the plant defines its zones, so ask for the current classification.

Why does the number of assets at Cilacap matter for safe equipment choice?

With more than 85,000 maintainable assets and an ongoing safety-critical-element review, the refinery is formalising what is classified and how it is maintained. That usually means device approvals and area classification records are checked closely, so bring documentation.

How wet does Cilacap get, and does it matter for a handset?

The climate is hot and humid with a heavy rainy season, so devices on tank farms and jetties meet rain often. Check sealing and charging arrangements. Rain protection is separate from explosion protection, so confirm the permitted device list with the operator.
