Braskem Idesa runs Etileno XXI, the ethane cracker and polyethylene complex at Nanchital in southern Veracruz, and has built ethane import capacity at Coatzacoalcos. This page is for the safety, process and telecoms teams who would need an explosion proof mobile phone for Braskem Idesa in Mexico to cover both flammable gas on the cracker and combustible dust in the polyethylene finishing area. The IS-04Z1 is designed for Zone 1 and Zone 21 duty, with certification in progress ahead of the Q4 2026 launch. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
Etileno XXI is a world-scale integrated site. Ethane is cracked to ethylene in a furnace section, and the ethylene is converted into polyethylene in separate high-density and low-density plants. Published figures put the complex at about 1.05 million tonnes a year of ethylene, with two HDPE plants and an LDPE plant making polyethylene. For a handset, that single footprint contains three different hazards: ethylene and ethane gas in the cracker and the polymer reactors, hydrogen in some process streams, and polyethylene powder and fines in handling, conveying and silo areas. A phone approved only for gas leaves half the plant uncovered, and one approved only for dust leaves the other half.
A cracker is run continuously and stopped rarely, so how the plant is staffed and maintained shapes the device more than any spec sheet.
Crackers operate for years between major shutdowns. During a planned turnaround the site fills with contractors working to a tight programme, and a fleet of handsets needs to be enrolled, tracked and returned by the day rather than managed one at a time.
An operator may start the shift in the furnace area, walk the ethylene section, and finish at the polymer silos. A handset that is valid for gas and dust on the same round avoids carrying one device for the cracker and another for the powder area.
Polyethylene powder and ethylene both carry static risks. Housing materials, surface finishes and the way a device is handled all matter, and the certificate documentation is where your electrical engineer checks them against the plant procedures.
Veracruz is hot and humid for much of the year, and furnace areas add radiant heat. IP68 sealing, rugged build and a T-class that suits the area drawing are what carry a unit through a shift outdoors.
Ask Braskem Idesa's procurement, safety and IT teams what a supplier must provide before a device is allowed on site, and do not assume that a general certificate answers every question. We have no relationship with the company and are not describing a programme.
An operator walks the cracker and polymerisation areas logging readings and photographing defects, with the site's own forms available on the handset. Position and photographs go into the same report, so the control room can find a fault without a verbal description.
In a shutdown, planners and contractor supervisors need permits, isolations and drawings close at hand. An enrolled device carries them offline and syncs on the plant network, and the MDM console shows which unit is with which contractor.
Where product or ethane moves through loading, unloading and storage, staff need a camera and a call on the same device while moving between classified and safe areas.
The IS-04Z1 design target is Zone 1 for gas and Zone 21 for dust, which is the combination a cracker with a polymer finishing area requires. Whether a specific silo or conveyor is Zone 21 or 22 is a decision for the plant's dust hazard assessment.
Ethylene is Group IIB, and hydrogen is Group IIC. The ATEX marking target of II 2 G Ex ib IIC T4 is designed to cover both, subject to certification, so the device group does not limit the choice.
Yes. The IS-04Z1 runs Android 16 with Android Enterprise and is managed from existing MDM consoles, so the plant can set app, camera and network policy in the same console it already uses.
No. SAMS has no agreement, pilot or approval from the company. The page describes where the device is designed to fit, based on publicly described plant operations.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Mexico. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
