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.

ATEX and IECEx Smartphone for ENAP
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 smartphone for ENAP, and where the IS-04Z1 stands against that list today.

WhereENAP
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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

Supplier approval · ENAP
How suppliers reach ENAP
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.

More about ENAP that matters for portable equipment
ENAP: industry on the ground
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.
ENAP: geography and layout
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: industry on the ground
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.
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 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.

Specifying an ATEX and IECEx smartphone for ENAP
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · ENAP
Frequently asked questions
Can ENAP buy the IS-04Z1 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 smartphone for ENAP cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
How does ENAP approve suppliers?
ENAP's website offers a supplier management portal (gestion de proveedores) for joining its vendor community and registering for procurement opportunities.
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.
Do Chilean refineries face particular seismic or coastal conditions for equipment?
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.
Which ENAP sites are likely to need Ex-rated mobile devices?
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.
How does ENAP's supplier portal affect a new device supplier?
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.
