Ex-Proof Smartphone Distributor in Duque de Caxias
Duque de Caxias is an industrial municipality on Guanabara Bay about 17 km from downtown Rio de Janeiro. It hosts the Petrobras Duque de Caxias refinery (Reduc), which started up in 1961, so refining and gas-processing units create Zone 1 areas. An Ex-proof smartphone distributor in Duque de Caxias would carry the IS-04Z1 to these buyers once certification completes.

The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Duque de Caxias. The sheet describes Zone 1 areas in refining and gas-processing units. A marking check at Reduc would look at zone suitability first, then gas group and temperature class for each unit's product, including the newer biofuel processing. The IS-04Z1 target marking II 2 G Ex ib IIC T4 is not yet certified.

Questions · Duque de Caxias
Frequently asked questions
Can we buy an Ex-proof smartphone in Duque de Caxias 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 Ex-proof smartphone in Duque de Caxias 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Duque de Caxias would use it?
Likely candidates are refinery process units, tank farms and pipelines, loading and dispatch areas, biofuel (saf and renewable diesel) processing. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Duque de Caxias?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Duque de Caxias.
How should I plan devices for a Rio de Janeiro refinery visit?
Typically choose a device with the right zone, gas group and temperature class, carry its certificate, and confirm local radio approval requirements. Many sites also require induction and an approved-equipment check at the gate, so allow time for that.
What does the refinery's lubricant and gas role mean for hazard types?
Lubricant plants and gas processing mean both flammable liquids and flammable gases can occur, sometimes with hydrocarbon vapours near ambient temperature. Ask the operator for the applicable gas groups; do not assume one device rating covers every unit.
Will the 2026 shutdowns affect when I should order?
Maintenance shutdowns of the coking and hydrotreating units are scheduled in 2026, which brings large contractor numbers into classified areas. Plan lead times early. Certification is in progress, so confirm schedules and requirements with the site operator and its HSE team.
