Retevis RT97P and E2: Long-Range Digital Communication for Oil Refineries and Chemical Plants

The Retevis RT97P portable repeater and the MateTalk E2 explosion-proof radios build a dedicated, far-reaching communication backbone for high-risk industrial facilities. The pairing targets reliable communication across vast hazardous sites such as large chemical plants, oil refineries, and mining operations. Together they form a safety-certified ecosystem: the E2 protects on-site personnel, the RT97P extends secure network coverage to remote areas, and both keep real-time safety alerts moving across the entire facility.

Engineered for Where Safety Cannot Compromise

In environments where flammable gases, vapors, or dust make every equipment choice critical, standard communication tools become a vulnerability. The Retevis RT97P and MateTalk E2 Kit is a communication and safety system designed to reduce risks, support operational continuity, and keep teams connected in oil and gas, chemical, mining, and heavy manufacturing sites.

Eliminating Dangerous Communication Blackouts & Isolation

Large, complex facilities inherently create silent zones: remote tank farms, deep processing areas, or isolated maintenance bays, where workers become dangerously disconnected. The portable RT97P DMR repeater works as the site network core. It extends the effective range of your radios and turns individual devices into a unified network, so workers stay reachable, which improves both safety and operational responsiveness across the facility.

The Certified Safe Core: Intrinsically Safe Hardware

At the heart of the system is the MateTalk E2 Intrinsically Safe Explosion-Proof Handheld Radio. As an ATEX and IECEx certified device, it is engineered for reliable operation in explosive hazardous areas containing flammable gas, steam, or combustible dust. Its explosion-proof and flame-retardant construction keeps the radio from producing an ignition source, so teams can communicate where standard electronics cannot be used.

Integrated Performance for Demanding Shifts

This system is built for clarity and harsh conditions. It leverages DMR digital technology for clear audio in extreme ambient noise, supported by AES256 encryption for secure communications. The MateTalk E2 radio is built to IP68 and MIL-STD-810G standards, withstands shocks and vibrations, and operates in temperatures from -10°C to +55°C. Its battery supports over 20 hours of digital talk time (over 14 hours in analog), and critical features such as Lone Worker monitoring, a one-touch emergency alarm with GPS location, and compatibility with major brands like Motorola support consistent performance through multi-shift operations.

A Rapid-Deployment, Scalable Solution

Time and flexibility matter in the field. This kit provides a turnkey solution: the compact RT97P repeater requires minimal setup and supports customizable UHF/VHF frequencies for your operational needs. Its multi-power options (AC, DC, vehicle, and solar) allow deployment for new site commissioning, temporary projects, or emergency response. The system is scalable, so you can start with a core kit and protect your long-term investment.

The Reliable Foundation for Operational Integrity

In high-risk environments, clear communication supports site safety. The Retevis RT97P and E2 Kit targets the silent gaps and signal failures that compromise safety in vast facilities. It provides a network that keeps teams connected and reduces the isolation and miscommunication risks of large sites, so crews can focus on the work itself while critical communication stays clear, reliable, and compliant.

  • Coverage in Large Facilities: the RT97P repeater extends coverage to remote areas, while E2 radios maintain secure links in classified zones for complete site connectivity. One Digital Network: a single DMR network reduces communication gaps in chemical plants, oil and gas facilities, and other sprawling operations. 
  • Compliance in hazardous locations: the system combines ATEX/IECEx-certified handhelds for explosive atmospheres with a repeater deployed in safe areas. Industrial-grade reliability: the system delivers DMR digital audio and is built to IP68 and MIL-STD-810G standards for consistent performance in harsh environments, which reduces communication system downtime. 
  • ATEX/IECEx Certified: The E2 ships with International IECEx Certificate No. IECEx CSAE 25.0058X and European ATEX Certificate No. CSANe 25ATEX1186X, and both certificates are available for download. For frequency customization, note your custom requirements when placing an order; after the frequency plan is confirmed, customization takes about 4 weeks, and the frequency is fixed afterwards. 

FAQ

The default kit ships with one RT97P DMR repeater, six E2 intrinsically safe handheld radios, an FRP antenna with ground-plane radials, and a coaxial cable. Larger bundles scale the radio count up to 50 and add headsets, mics, or large PTT buttons.

The E2 is an ATEX and IECEx certified device engineered for explosive hazardous areas containing flammable gas, steam, or combustible dust. Its energy-limited circuits, anti-static housing, and flame-retardant construction keep the radio from producing an ignition-capable spark or hot surface.

The E2 ships with International IECEx Certificate No. IECEx CSAE 25.0058X and European ATEX Certificate No. CSANe 25ATEX1186X, and both certificates are available for download on this page. ATEX covers EU explosive atmospheres under directive 2014/34/EU, while IECEx is the international certification scheme.

The kit targets oil refineries, chemical plants, and mining operations, plus fuel terminals, tank farms, and other flammable or combustible dust sites. Recent inquiries came from a chemical plant replacing 120 Motorola radios, a fuel terminal running tanker discharges, and a security company buying 30 ATEX radios.

The E2 runs DMR digital, the same technology family as the Motorola MOTOTRBO line, and this page states compatibility with major brands like Motorola. A chemical plant running 120 XPR3300e radios on a repeater system recently requested this replacement path, so send your frequency plan and fleet size for a migration quote.

Yes. The MateTalk E2 is built to IP68 and MIL-STD-810G standards, so it withstands shocks, vibrations, dust, and heavy rain in harsh industrial environments. Note that the IP68 rating belongs to the handheld; the RT97P repeater is deployed in safe areas and its own ingress rating is not stated on this page.

The E2 battery supports over 20 hours of digital talk time and over 14 hours in analog mode, which covers multi-shift operations between charges. Actual runtime varies with transmit time and power level, and Lone Worker monitoring adds a safety layer for long shifts.

Yes, within DMR rules. The E2 operates on DMR digital with kit-programmable frequencies, and this page states compatibility with major brands like Motorola. A recent buyer asked the same question about pairing the E2 with Retevis NR40 radios; same-frequency, same-code programming is the path, and the programming software details should be confirmed before ordering.

This page does not quote a specific coverage distance. Repeater reach depends on antenna height, terrain, and site layout, so the repeater should sit at a high point in a safe area with clear sightlines to the work zones. Share your site layout to get a coverage assessment before ordering.

The RT97P supports customizable UHF/VHF frequencies to match your operational needs. You note your custom frequency when ordering; after the frequency plan is confirmed, customization takes about 4 weeks, and the frequency is fixed afterwards.

After you confirm the custom frequency plan, customization takes about 4 weeks. The frequency is fixed after customization, so lock down your site license and channel plan before ordering. This applies to the repeater and handhelds ordered as one kit.

Deploy the RT97P in a safe area outside the hazardous zone. The certified handhelds enter classified areas; the repeater itself carries no ATEX rating on this page, so it stays in a control room, office side, or another non-hazardous location with antenna height over the site.

They must be. Intrinsic safety applies to the whole device ecosystem, so batteries, speaker mics, headsets, and earpieces used with the E2 must carry matching certifications; a non-approved accessory instantly voids the safety rating. The kit variants that add headsets, mics, and PTT buttons ship with E2-matched accessories, and certification documents are available on request.

Yes, in most countries a frequency license is required for DMR radio operation, and some governments mandate dedicated licensed frequencies. A recent inquiry from a site regulated under the CITRA licensing framework shows this in practice: licensed dedicated frequency operation was required by government regulation. Confirm local rules before ordering.

Eight bundle options cover 6, 10, 20, or 50 E2 radios, and the headset bundles add 10 or 20 headsets with mics or large PTT buttons. You can also order the E2 5-pack with bone conduction headsets and large PTT buttons as an add-on, so fleets scale in one purchase.

ATEX and IECEx certification covers explosive atmospheres, not cleanroom classifications, so the E2 should not be assumed cleanroom-compliant. A radiopharmacy manufacturing facility with grade B and C cleanrooms asked this exact question; send your cleanroom zone class and requirements so the team can confirm suitability in writing.

The RT97P is a DMR digital repeater and pairs with the E2 for hazardous sites. The RT97L is an analog GMRS repeater that pairs with NR30 or RB26 handhelds for farms and ranches. Choose the RT97P kit when your facility requires certified radios or runs DMR fleets; choose the RT97L kit for standard GMRS use.

The related E1 bundle pairs the same RT97P repeater with the E1 DMR handheld radio. The E1 version is listed without ATEX or IECEx certification on its card, so treat the E2 as the certified option for hazardous zones and the E1 bundle for sites that need DMR coverage without explosive atmospheres. Confirm the E1 certification status before ordering.

Yes. The E2 includes a one-touch emergency alarm with GPS location reporting and Lone Worker monitoring for shift safety. These features run across the certified radio ecosystem of this kit, so a worker raising an alarm in a classified zone is reachable through the repeater network in real time.

Yes. The RT97P is a portable repeater in a compact case-style chassis with a handle, an LCD, and up and down keys, and it supports AC, DC, vehicle, and solar power options for rapid deployment. Its size and weight are archived at 280 x 210 x 75 mm and 2,624 g from the RT97P page.

The E2 supports AES256 encryption for secure digital communications over DMR, which protects sensitive operational traffic in industrial sites. Combined with customizable frequencies, this keeps plant communications private across the repeater network.

Current add-ons include the E2 5-pack with bone conduction headsets and large PTT buttons ($3,343.99) and the earhook earpiece for the MateTalk E2 ($79.99 per 5 packs). Spare batteries, chargers, and other IS-certified accessories should be confirmed with the team, since only certified accessories maintain the intrinsically safe rating.
