Explosion-Proof Smartphone for ENAP
ENAP is Chile's state-owned petroleum company, created by law in 1950 and based in Santiago. Its subsidiary ENAP Refinerias operates three refineries, Aconcagua, Bio Bio and Gregorio, with a combined capacity of about 238,000 barrels a day, which represents all of Chile's refining capacity. This page explains what to look for in an explosion proof smartphone for ENAP, and where the IS-04Z1 stands against that list today.

Supplier approval · ENAP
Supplier registration at 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 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.
ENAP: who works there
ENAP Sipetrol, the international exploration and production subsidiary founded in 1990, has operations in Argentina, Ecuador and Egypt, so equipment standards may differ between Chilean and overseas assets.
ENAP: background
ENAP was created by Law No. 9618 on 19 June 1950 to prospect for and exploit oil in Tierra del Fuego and the Strait of Magellan, where deposits had been found between 1945 and 1950.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In ENAP. In ENAP refineries, 'explosion-proof' is a casual phrase for several concepts. Flameproof Ex d protects fixed motors and enclosures in process units, while intrinsic safety limits the energy of a portable device. A phone used on refinery rounds or at a marine terminal is a handheld, so the IS-04Z1 is designed around intrinsic safety.

Specifying an explosion proof 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 explosion proof 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 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still 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.
