Hungary: infrastructure
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.

Hungary: who works there
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.
Hungary: industry on the ground
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.
Hungary: industry on the ground
The Matra power plant, the last coal electricity producer, supplied about 9% of Hungary's electricity in 2020 and was served by coal mines in Visonta and Bükkábrány, with a gas combined-cycle replacement planned.
The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Hungary. Hungarian plants combine in-house staff and contractors, so EMM or MDM enrolment is useful for provisioning and removal. The IS-04Z1 is designed for managed deployment. Charging belongs in a safe area, and Hungarian-language set-up and connectivity at gas storage and refinery sites should be agreed beforehand.

Specifying an industrial mobile phone for Hungary
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Hungary
Frequently asked questions
Can we buy an industrial mobile phone in Hungary today?
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.
What does an industrial mobile phone in Hungary cost?
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.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
Which sites in Hungary does this cover?
The market guide for Hungary covers Százhalombatta, Tiszaújváros, Kazincbarcika, Dorog, among others. Site-level pages are linked below.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
How does Hungary's winter weather affect Ex handheld devices?
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.
Which Hungarian companies run the main classified-area sites?
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.
Can one device cover both a refinery and a pharmaceutical plant?
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.
