Industrial Smartphone in São Paulo

Sao Paulo is Brazil's largest city and an industrial state. The city itself is not a refinery site, but the state hosts four Petrobras refineries: Replan at Paulinia (415,000 barrels a day), Revap, RPBC at Cubatao and Recap at Capuava. This page explains what to look for in an industrial smartphone for Sao Paulo state, and where the IS-04Z1 stands against that list today.

More about Sao Paulo state that matters for portable equipment

Sao Paulo state: who works there

Replan at Paulinia, in Sao Paulo state, is Petrobras' largest refinery at 434,000 b/d, and the 2024-28 plan includes new units and upgrades there.

Sao Paulo state: projects and investment

Petrobras plans revamps at the Presidente Bernardes refinery and Replan, an aviation bio-kerosene plant at RPBC and a combustion boiler at the Capuava refinery, all in Sao Paulo state.

Sao Paulo state: industry on the ground

Sao Paulo is Latin America's largest urban economy, representing around 10 percent of Brazil's GDP, and is home to the B3 stock exchange, so many contractors and procurement teams are based there.

Sao Paulo state: climate and equipment wear

São Paulo has a humid subtropical climate, and heavy storms can bring more than 140 mm of rain in 24 hours, so outdoor and plant-yard work needs weather protection for portable equipment.

The term · industrial

What “industrial” means for a smartphone

“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.

The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.

In Sao Paulo state. Many industrial buyers and distributors keep offices in the city while plants are in other municipalities, so a central EMM or MDM policy suits fleets that cover several sites. Charging is done in safe areas. Road links help deliveries and service between the city and the refineries.

Questions · São Paulo

Frequently asked questions

Can we buy an industrial smartphone in São Paulo 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 industrial smartphone in São Paulo 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 an industrial phone as well as an Ex phone?

Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.

Which areas at Sao Paulo state would use it?

Likely candidates are refinery process units, tank farms, pipeline terminals, fuel storage and loading. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.

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.

How long does equipment take to reach Sao Paulo state?

Imports usually clear through Santos and travel by highway, but customs and radio approval can add time, so allow a margin. Confirm clearance steps with a local agent early in the project.

What does a Replan visit usually involve?

Typically a gate induction, a permit system and equipment checks at one of Brazil's largest refineries. Confirm with the contractor which zones you will enter and whether your devices need Ex certification and local radio approval.

Does one approval cover all the state's refineries?

Not by assumption. Each plant has its own classification and procedures, and purchasing is usually through registered-supplier processes. Ask each operator for its Ex equipment policy and obtain the area classification for the specific unit before ordering.
