Hungary: industry on the ground
Wanhua-BorsodChem, based at Kazincbarcika in north-east Hungary, produces isocyanates (MDI and TDI), PVC and chlor-alkali products, and is a major chemical employer for plant maintenance and shutdown contractors.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for Hungarian refinery units, polymer plants, pharmaceutical solvent areas and gas installations. MOL is active in exploration and production, refining, distribution, petrochemicals, power generation, trading and retail, with operations in over 30 countries and 2,400 service stations in ten countries as of 2025. Distribution partners for Hungary are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Hungary 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Hungary. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Wanhua-BorsodChem, based at Kazincbarcika in north-east Hungary, produces isocyanates (MDI and TDI), PVC and chlor-alkali products, and is a major chemical employer for plant maintenance and shutdown contractors.
MOL was established on 1 October 1991 as the legal successor of nine members of the National Oil and Gas Trust, which dated from 1957, giving Hungary a long industrial oil and gas history.
Four operating reactors built between 1982 and 1987 form the Paks Nuclear Power Plant, and nuclear is the main domestic energy source, with almost half of Hungary's energy imported as of 2024.
MOL's Danube Refinery at Százhalombatta started up in 1965 and has a capacity of about 8.1 million tonnes a year, making it one of the largest refineries in Central and Eastern Europe.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Hungary. Rounds at Hungarian refineries, crackers and gas compressor stations cover many zones in one shift. In pharmaceutical plants, solvent rooms may be entered many times a day. An intrinsically safe handheld lets staff record readings and checks at the point of work. That is the design intent, pending certification.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Hungary 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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.

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 Hungary.
Continental winters can bring sub-zero temperatures, which reduce battery capacity. Check the lowest rated ambient temperature on the certificate and whether touch input works with gloves. Plan spare batteries and warm storage for outdoor work at refineries and pipeline stations.
MOL is the largest integrated oil, gas and petrochemical group, and the Paks plant and gas network operators also have hazardous areas. Each company runs its own supplier approval, so contact its procurement and HSE teams for current device and contractor requirements.
Gas groups, dust and temperature needs differ between a refinery and a solvent suite. A device would need a marking that suits each classification. Check each plant's zone documents, since the answer depends on the operator's classification rather than the device alone.
