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. An Ex-proof smartphone distributor in Jamnagar, Gujarat would carry the IS-04Z1 to these buyers once certification completes.

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.
The companies on site and the hazardous-area types a handset is likely to meet there.
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 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.
Jamnagar has a hot semi-arid climate, with March to May extremely hot and humid and an erratic monsoon averaging about 500 millimetres, from under 100 in dry years to over 1,500.
Polymer exports from the Jamnagar complex were moved through Port Pipavav by container, with volumes quadrupled to over 10,000 forty-foot containers in one year.
A second large refinery is at nearby Vadinar and is owned by Nayara Energy, described as India's second-largest single-site refinery.
“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 Jamnagar, Gujarat. A marking check at Jamnagar would compare the device against each unit, since gasification, cracker and tank farm areas may involve different gases. Hydrogen-rich streams point to the most demanding gas group, while fuel storage can sit lower. The IS-04Z1 target marking is II 2 G Ex ib IIC T4.
A distributor for Jamnagar, Gujarat would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
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.
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.
