Rugged Mobile Phone in São Paulo
Replan started operating in 1972 on about 9.1 km2, with capacity of 66,000 m3/d, and makes gasoline, diesel, LPG, aviation kerosene, asphalt, petrochemical naphtha and propane. 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 a rugged mobile phone for Sao Paulo state, and where the IS-04Z1 stands against that list today.

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 · rugged
What “rugged” means for a smartphone
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Sao Paulo state. Plants in the state are inland and coastal, with outdoor process areas exposed to rain, heat and dust. IP68 gives strong ingress protection for such conditions. It is not an explosion-protection rating, and the Ex marking remains the operator's focus.

Questions · São Paulo
Frequently asked questions
Can we buy a rugged mobile phone 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 a rugged mobile phone in São Paulo cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
How rugged is the IS-04Z1?
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are 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.
