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.

Intrinsically Safe 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. If you are specifying an intrinsically safe smartphone for ENAP, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Supplier approval · ENAP
Becoming an approved supplier to 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 · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In ENAP. Rounds across refinery process units, fuel storage and the marine terminals at Quintero and San Vicente involve reading gauges, photographing equipment and filing permits. A handheld designed as intrinsically safe could carry that on one device. The IS-04Z1 is designed for this, though certification is still in progress.
The route · specification
Specifying an intrinsically safe 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 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.
What does an intrinsically safe smartphone for ENAP cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
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.
