An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Vadinar India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
The refinery was built by Essar Oil, started up in 2006 and now trades as Nayara Energy. A delayed coker unit was added in 2012.
Integrated port access takes vessels up to 350,000 DWT. Vadinar also has Deendayal Port Authority and Indian Oil single buoy moorings, with port expansion under way.
The nearest airport is at Jamnagar, 47 kilometres away, and Vadinar is a small coastal town in Devbhumi Dwarka district.
The Bharat Oman Refineries crude oil terminal is also at Vadinar and supplies its refinery at Bina in Madhya Pradesh.
The Jamnagar area has a hot semi-arid climate with extremely hot and humid conditions from March to May and an erratic monsoon of about 500 millimetres.
The Marine National Park at Narara Island lies about 7 kilometres from the town, and a salt production unit operates locally.
“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 Vadinar, Gujarat. A marking check at Vadinar should relate the device to the process units, delayed coker, tankage and mooring areas. Coker and fuel streams can fall into different gas groups. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, and the operator's classification decides suitability.
A distributor for Vadinar, 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, delayed coker, single buoy mooring and tankage, product dispatch by sea, rail and road. 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 Vadinar, Gujarat.
March to May is extremely hot and humid, the monsoon is erratic and cyclones sometimes occur. Choose sealed devices with a wide operating temperature range.
Indian Oil's terminal is secured by the Central Industrial Security Force, so expect ID checks and prior permits. Arrange passes with the operator well in advance.
No. Each site has its own operator, classification and permit rules, so approval at one does not carry to the other. Contractors serving both should confirm requirements with Nayara Energy and with the Jamnagar operator separately.
