Jamnagar, on the Gulf of Kutch coast in Gujarat, hosts Reliance Industries' refining complex at Motikhavdi, which Reliance describes as the world's largest single-site refinery at 1.4 million barrels a day. Process units, tank farms and marine facilities create extensive Zone 1 and Zone 2 areas. Distribution partners for Jamnagar, Gujarat are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Jamnagar, Gujarat has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Jamnagar, Gujarat: Refinery process units, Petcoke gasification, Refinery off-gas cracker and petrochemical units | Classified by the site operator |
An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Jamnagar India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Wikipedia gives the refinery's commissioning as July 1999 and the site as over 7,500 acres, with utilities, port infrastructure and worker housing. Reliance's own site lists a refinery off-gas cracker and the world's largest petcoke gasifier.
Reliance states that its marine infrastructure takes vessels from small chemical carriers to very large crude carriers.
The complex covers over 7,500 acres and includes utilities, port facilities and a 415-acre township for about 2,500 employees, according to a 2013 description.
The refinery was commissioned within 36 months, which means much of its equipment dates from around the turn of the century.
Jamnagar is known as the Brass City, with over 5,000 large and 10,000 small brass workshops, so local engineering and fabrication skills are widely available.
The Jamnagar refinery, owned by Reliance Industries, was commissioned in July 1999 at 668,000 barrels a day and now has an installed capacity of 1.24 million barrels a day, the largest of any single refinery.
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 Jamnagar, Gujarat. Jamnagar sits on the Gulf of Kutch coast, so salt air, heat and dust affect devices left outdoors. An IP68 rating helps against dust and splashing during long outdoor shifts. It is an ingress rating only, so it neither replaces nor implies Ex protection for any classified area.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Jamnagar, Gujarat yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
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.
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.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
Likely candidates are refinery process units, petcoke gasification, refinery off-gas cracker and petrochemical units, crude and product tank farms. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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 Jamnagar, Gujarat.
The refinery complex handles over a million barrels a day plus petrochemical units and port facilities, so classified areas are extensive. The operator sets the zones and equipment rules, so confirm them before entering.
The area has a large industrial and fabrication base, including thousands of brass workshops, and a workforce that mostly speaks Gujarati. Operators still require site induction, so plan time for approvals.
Large sites mean long walks and long shifts, so battery life, charging points and a robust housing matter. Charging must happen in safe areas, not in classified ones. Ask the operator what charging and spare-device arrangements are permitted before planning a fleet.
