Explosion-Proof Radios for Oil & Gas — ATEX/IECEx Zone 1 & 2 Terminals, TETRA and DMR
Intrinsically safe handhelds and repeaters for refineries, offshore platforms, LNG plants and petrochemical facilities where ignition risk is absolute.
Why Standard Radios Fail Here
Zone 1/2 Explosive Atmospheres
Flammable gas, vapor and dust clouds require intrinsically safe (IS) ATEX/IECEx certification — non-certified radios are a fire hazard.
Offshore Corrosion & Humidity
Salt spray and humidity attack electronics. IP67/IP68 sealing and marine-grade housings are mandatory on platforms.
Emergency Shutdown Communication
Process upsets demand instant, prioritized communication with alarm override and man-down alerting.
Multi-Site Control Rooms
Refineries span kilometers. DMR IP Site Connect and TETRA networks unify terminals, mobiles and dispatch consoles.

Recommended Deployment Blueprint
Typical deployment: MTP6550/MTP8550Ex TETRA terminals for control-room and offshore crews, DP4401Ex/DP4801Ex DMR IS handhelds for field maintenance, DR3000 repeaters with IP Site Connect linking process units, and man-down monitoring feeding the safety operations room.
Deep Technical FAQ
What is the difference between ATEX and IECEx certification?
ATEX is the EU directive (2014/34/EU) for explosive atmospheres; IECEx is the international equivalent scheme. Most global projects accept either, but Middle East and Asia tend to specify IECEx while EU projects specify ATEX. Both certifications are available on RadioSysHub-sourced units.
Can I use TETRA radios on an offshore platform?
Yes. The MTP6550 and MTP8550Ex are ATEX-certified TETRA terminals with man-down sensors — the MTP6550 delivers 1.8W Class 3L output and the MTP8550Ex is gas and dust proof for Zone 1/2 offshore use.
Do you supply intrinsically safe batteries and accessories?
Yes. We stock ATEX batteries such as the NNTN8359 IMPRES Li-ion for DP4401Ex and the PELTOR PMLN6333 ATEX headset — all certified accessories to match the terminal.
How do you handle radio programming for hazardous areas?
Programming is completed and sealed before dispatch. We configure your licensed frequencies, group calls, emergency channels and man-down profiles, with documentation certifying the installed configuration.
