Mathura refinery stands on the Delhi-Agra highway, and has supplied the northern market since 1982. It processes crude that arrives by pipeline and sends products out by pipeline, rail and road. It also sits inside the Taj Trapezium Zone, so it operates under tighter environmental scrutiny than most refineries. For the people on its units, a handset decision is part of a documented safety file. The SAMS IS-04Z1 is pre-launch: certification is in progress and no certificate has been issued.
Launching Q4 2026 · ATEX and IECEx certification in progress
The refinery has been expanded since it was commissioned. It is an older, compact inland refinery rather than a petrochemical estate, so the classified areas are the familiar refinery set: distillation, conversion, treating, tankage and despatch. Crude comes in through the Salaya-Mathura pipeline, and finished products leave on several product pipelines and by road.
Mathura is an inland refinery on the northern plain, run under unusual environmental scrutiny. That combination makes documentation, heat tolerance and managed devices more relevant than salt or monsoon surge.
Mathura's summers are long and hot, and winters are cooler. The handset must hold its sealing and battery behaviour through both. The certified ambient range is whatever the certificate states, so an evaluation unit should be tested on an afternoon shift in the hot months, not only in an office.
The refinery lies in the Taj Trapezium Zone, where environmental rules on industry are tighter than elsewhere. Operators there are used to documentation. A device with a certificate and control drawing on file fits that culture better than one accepted by a verbal assurance.
Hydroprocessing runs hydrogen-rich gas, which sits in group IIC, while sulphur recovery involves hydrogen sulphide. The IS-04Z1 targets II 2 G Ex ib IIC T4 for the gas rating, but no phone replaces a personal gas detector. The device can pair with a detector over Bluetooth to log readings.
A refinery commissioned in 1982 spreads its units over a large footprint, and a socket in a safe area can be a long walk from the work. A 4,000 mAh battery specified around a full shift matters more here than a headline feature count.
Safety audits at a long-running refinery reward traceable records: certificate, control drawing and conditions of safe use. None of these exists for the IS-04Z1 yet. When it does, SAMS would expect the operator's HSE team to review it against its own area classification before any unit is issued.
Operators, contract workmen and visiting engineers share the site. Android 16 supports English and Hindi with enterprise management, and EMM enrolment lets the shift in-charge restrict applications or switch off the camera where photography is not allowed.
An outside operator on a unit round logs readings, photographs a leak at a flange and reaches the control room from the same sealed device. The saving is a report written at the equipment rather than recalled later. Where the device may be carried is set by the certificate and the site's classification.
On sulphur recovery and treating units, the detector worn by the person is the safety device. Pairing it with a handset over Bluetooth lets a reading be logged against the asset tag and sent to the shift in-charge, so the record follows the person rather than a paper form.
Products leave Mathura on pipelines to Delhi, Agra and Bharatpur and by road. Staff at despatch points and pipeline stations check pressures, seals and loading. A phone that photographs a seal, scans a tag over NFC and sends the record onward saves a trip back to a terminal.
In a shutdown, electricians, scaffolders and inspectors share a bay on different permits. A managed phone holding the permit, isolation list and a contact directory keeps the permit holder in the unit. Whether it is accepted is decided by the operator's own procedures.
Not yet. The IS-04Z1 is pre-launch and its IECEx, ATEX and NEC 500 Class I Div 1 certification is in progress at TÜV in Germany ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the 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. Indicative pre-launch pricing can be issued in writing against a stated quantity and site, and any firm figure for an uncertified Ex handset should be treated with caution.
The zone regulates industry and emissions, not handsets, so it does not set an equipment standard. Its relevance is cultural: operators in the zone work under close scrutiny and keep careful records. Hazardous-area equipment is governed by PESO approval and the operator's own rules, which IndianOil's HSE team can confirm.
Group IIC, because hydroprocessing units run hydrogen-rich gas and hydrogen sits in IIC. The IS-04Z1 marking target is II 2 G Ex ib IIC T4, so one device is intended to cover the site. The classification drawings and the final certificate decide where it may go, not the datasheet.
Support and repair would come from SAMS together with the local partner SAMS is appointing for India. No partner, stock or service point is announced yet. Ask early about exchange times and spares, because a sealed Ex device should only be opened by an authorised centre.
Only if IndianOil accepts them. Equipment rules are set by the operator for each site and job. EMM enrolment lets the operator push its own camera and application policy onto a contractor phone for the work, and remove it when the crew leaves.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for India. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
