Aluminum Alloy Explosion-Proof Telephone

To meet the increasing demand for secure and stable industrial communication, J&R Technology Ltd, a leading manufacturer of industrial telecommunication equipment, proudly introduces its new Aluminum Alloy Explosion-Proof Telephone. Built for the world’s most demanding environments, this robust device combines certified explosion-proof safety, superior communication quality, and intelligent design to ensure uninterrupted connectivity in critical applications.

1. Engineered for Safety and Strength

Constructed with a high-strength aluminum alloy die-cast housing, the telephone delivers exceptional mechanical durability and impact resistance. Its surface features an anti-corrosion powder coating, making it resistant to oil, acid, alkali, and salt spray—ideal for long-term deployment in outdoor or offshore locations.

The device is IP66/IP67/IP68 rated, providing complete protection against dust and powerful water jets. It performs reliably in offshore platforms, refineries, chemical plants, tunnels, and marine environments.

Certified under ATEX and IECEx standards with explosion-proof ratings of Ex eb ib [ib Gb] mb IIC T6/T5 Gb, Ex ib [ib Db] tb IIIC T80℃/T95℃ Db, the unit is fully compliant with IEC requirements. Flame-retardant internal wiring and sealed cable entries prevent the risk of sparks, arcs, or ignition, ensuring total operational safety in gas or dust hazardous areas.

2. Superior Audio and Communication Performance

Industrial environments are often noisy and chaotic — that’s why this telephone is designed for crystal-clear voice quality.
Equipped with a high-sensitivity handset and digital noise suppression technology, the telephone ensures clear communication even in environments exceeding 90 dB.

Supporting both analog (PSTN) and VoIP SIP protocols, it allows flexible network integration. Remote configuration, live status monitoring, and self-diagnostic features further help maintenance teams minimize downtime and enhance operational efficiency.

3. Designed for Industrial Realities

Every design element has been optimized for industrial reliability and user safety:

• Fully sealed, corrosion-resistant enclosure, suitable for dusty, humid, or chemical-laden environments.

• Anti-tamper handset with stainless-steel armored cord, providing resistance against mechanical stress and vandalism.

• Heavy-duty rubber keypad with programmable speed-dial buttons for fast emergency or control room calls.

These details ensure dependable 24/7 operation with reduced maintenance and longer service life.

4. Modular and Customizable Options

The Aluminum Alloy Explosion-Proof Telephone offers multiple intelligent add-ons to suit different project needs:

• Flashing beacon and loud ringer for incoming or emergency alerts;

• PA/intercom interface for integration with plant communication or paging systems;

• Call recording and monitoring modules for centralized management;

• Keypad-free emergency versions for hotline or SOS installations.

Its versatility makes it ideal for applications across oil & gas, petrochemical, marine, power generation, mining, railways, tunnels, and offshore wind industries.

5. Built for the Future of Industrial Communication

The new explosion-proof telephone demonstrates J&R Technology’s continuous pursuit of innovation, safety, and reliability. Combining advanced engineering with practical functionality, it provides a robust communication lifeline for workers in hazardous areas.

Whether coordinating field operations or responding to emergencies, users can depend on J&R’s explosion-proof telephone to deliver clear, secure, and reliable communication — when it matters most.
