ENAP: logistics and access
The three refineries supply over 80% of Chile's fuel needs, so plant shutdowns and maintenance programmes have national importance and are scheduled carefully with contractors.
ENAP is Chile's state-owned petroleum company, created by law in 1950 and based in Santiago. Through ENAP Refinerias it runs the Aconcagua, Bio Bio and Gregorio refineries, with combined capacity of 238,000 barrels per day, covering all of Chile's refining capacity. This page explains what to look for in an ATEX and IECEx mobile phone for ENAP, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for ENAP: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |
| Where it applies | ENAP: Refinery process units, Fuel storage and loading, Marine terminals | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Chile. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of its operations and the kinds of classified area that matter for portable equipment.
ENAP's website offers a supplier management portal (gestion de proveedores) for joining its vendor community and registering for procurement opportunities. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.
The three refineries supply over 80% of Chile's fuel needs, so plant shutdowns and maintenance programmes have national importance and are scheduled carefully with contractors.
ENAP lists the main units at its Aconcagua refinery as including topping and vacuum, catalytic cracking, delayed coking, hydrocracking, alkylation, isomerisation, sulphuric acid and sulphur plants, with a flare system and its own emergency response brigade and fire station.
The company is state-owned and based in Las Condes, Santiago, while its original oil exploration area lies far south in Tierra del Fuego and the Strait of Magellan.
ENAP is engaged in exploration, production, refining and marketing of hydrocarbons and their derivatives, so hazardous areas include refinery units, product storage and fuel distribution points.
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 ENAP. An ENAP reviewer assessing a handset for the Aconcagua, Bio Bio or Gregorio refinery would expect a certificate of conformity, schedule of conditions and legible marking. Dual ATEX and IECEx evidence helps international contractors and EPCs working on Chilean refineries and terminals. The IS-04Z1 certification is in progress and nothing has been issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.

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.
Chile is seismically active and two of the refineries are coastal, so sites typically apply robust fixing, corrosion protection and emergency procedures. For handheld devices this means checking drop resistance and sealing. Confirm each site's conditions and rules with the refinery directly.
The three refineries at Aconcagua, Bio Bio and Gregorio are the main process sites, with storage and loading areas, and the southern production areas are another. Zoning is decided per installation, so ask ENAP's HSE or maintenance teams for area classification drawings before specifying devices.
ENAP's website offers a supplier management portal for joining its vendor community and registering for procurement opportunities. A new supplier would use it, then meet ENAP's technical and HSE requirements. Confirm current steps with ENAP. The IS-04Z1 has no certificate yet, so no approval can be claimed.
