As RETEVIS celebrates its 15th anniversary under “15 Years in Sync, Powered by Your Trust,” RETEVIS announces its first intrinsically safe DMR radio-MateTalk E2, engineered for refineries, chemical plants, food processing, and other high-risk zones.
1. Introduction: A Milestone with Purpose
Since 2010, RETEVIS has established itself as a trustworthy/reliable global leader in two-way radio communications, earning user confidence across education, retail, small security, and beyond. As it enters its 15th year, RETEVIS is turning to more challenging terrains: industrial safety and communications in hazardous zones. The anniversary period from October 23 to November 11 serves not only as celebration but as brand reaffirmation and positioning push into intrinsically safe communications.
With RETEVIS Intrinsically Safe Radios and its flagship MateTalk E2, RETEVIS signals a bold extension—bringing its design heritage and commitment to innovation to environments with professional explosive gas, dust, and risk.
2. Brand Legacy & Product Evolution
RETEVIS began in 2010, focused on reliable two-way radio products design and development.In 2013, it released the RETEVIS H777 — a lightweight, license-free radio that became Amazon’s #1 in its category, adopted in schools, churches, retail, hospitality, and small security.Over the past 15 years RETEVIS incrementally refined that platform: improved USB-C easy universal charging upgraded belt clips, antennas, firmware, and user experience.
In 2023, RETEVIS Industrial Two Way Radio concept (durability, environmental adaptability, protection) introduced and launched the RETEVIS RB48 series for commercial harsher environment.
In 2025, RETEVIS Intrinsically Safe Radios now is extends into hazardous-area communications , first of which is MateTalk E2—targeting environments with flammable gases, combustible dust, volatile chemicals, and explosion risk.
3. Why Intrinsically Safe Communications Matter
In environments like refineries, chemical plants, food processing with dust, gas transport pipelines, and storage with volatile substances, conventional radios pose serious hazards. A spark, overheating, or electrical discharge can trigger catastrophic explosions.
Hence, intrinsically safe radios are critical — designed so that even under fault conditions they cannot ignite a hazardous atmosphere. RETEVIS Intrinsically Safe Radios- new MateTalk E2 addresses this needs with fully certified and robust design.
4. RETEVIS Intrinsically Safe Radios- MateTalk E2: Safety, Certification & Features
- a) Safety & Certification
Meets ATEX Zone 1 / Zone 2 standards, Certifications: Ex ib IIB T4 Gb / Ex ib IIIC T130 °C Db
International certifications: ATEX II 3GD / Ex ic IIC T4 Gc / Ex ic IIIC T100 Dc
Unlike many “explosion-proof” radios capped at IP65, MateTalk E2 achieves IP68-level protection: tested underwater at 1 m for 1 hour
- b) Key Design & Functional Features
| Category | Feature | Benefit for Hazardous Environments |
| Ingress protection | IP68 (full dust- & waterproof) | Withstands moisture, cleanup sprays, dust ingress in harsh zones |
| Energy-limited & fail-safe circuits | Design to limit spark risk under faults | Safe even under short / overload scenarios |
| Temperature control & heat management | Thermal control to keep surface < T4 limit | Avoids surface ignition risk |
| Ergonomic housing & sealing | Sealed buttons, robust enclosure | Safe operation and durability in harsh conditions |
| DMR digital core | Efficient modulation, lower power draw | Lower heating, better battery life, consistent communication |
| Audio & clarity | Advanced noise filtering, voice clarity | Reliable voice in noisy plants |
| Solo / lone worker mode | Safety features for workers in isolation | Worker protection in remote or confined areas |
| Battery & power management | Long battery life, safe battery chemistry | Ensures full-shift operation without risk |
| Reliability & redundancy | Redundant circuits, protective barriers | Maintains safety under fault conditions |
- c) Human Safety Focus
Lone Worker Mode: if operator fails to respond or presses no button within time, it triggers an alert
Emergency / priority interrupt: critical calls always get through
These features make MateTalk E2 suitable for demanding, safety-critical environments like petrochemical, refining, gas pipelines, food factories with dust zones, and chemical processing.
5. RETEVIS Intrinsically Safe Radios- Application Scenarios & Value
Refineries & Petrochemical Complexes
Communication among field operators, control rooms, and inspection teams in explosive gas/vapor zones demands intrinsically safe radios. MateTalk E2 ensures safe, reliable voice without ignition risk.
Chemical Manufacturing & Processing Plants
Chemical reactions, vapor emissions, and dust particulates create high-risk zones. MateTalk E2 can be deployed across zones, enabling critical inter-department communication (e.g. reactor areas, mixing halls, pipelines).
Gas / Pipeline Transport & Storage
Gas handling, compression stations, valves, and storage facilities present continuous explosion risk. Intrinsically safe radios like E2 maintain safe communications across maintenance, monitoring, and emergency response.
Food / Grain / Powder Processing Plants
Dust from powders, flour, sugar or other fine particles can be combustible. Even in food processing environments, internal dust can create explosion risk. MateTalk E2’s dust-safe design makes it suitable.
Laboratories / Material Handling with Volatile Solvents
Where volatile solvents, chemicals, or vapors are used, safe radios are essential. The E2 model combines high-safety design with practical usability.
In each scenario, the value proposition includes safety, operational continuity, clear communication under noise, and regulatory compliance.
