As industrial operations expand into more complex and hazardous environments, the demand for secure and reliable communication has never been greater. Rising to this challenge, J&R Technology Ltd, a global leader in industrial communication solutions, is proud to introduce its latest innovation — the Aluminum Alloy Explosion-Proof Telephone. Designed for the toughest conditions, this new model delivers uncompromised safety, exceptional durability, and clear communication, even in the harshest industrial settings.

1. Built to Withstand the Harshest Environments

At the heart of the new design is a high-strength aluminum alloy die-cast enclosure, providing superior mechanical strength and impact resistance. The housing is coated with a special anti-corrosion powder finish, ensuring long-term protection against oil, acid, alkali, and salt spray — ideal for offshore platforms, refineries, and chemical plants.

With an IP66/IP67/IP68 protection rating, the telephone guarantees complete resistance to dust, water, and environmental damage.
It is ATEX and IECEx certified for explosive atmospheres (Ex eb ib [ib Gb] mb IIC T6/T5 Gb, Ex ib [ib Db] tb IIIC T80℃/T95℃ Db), ensuring safe operation in hazardous gas and dust zones. The design features flame-retardant wiring, sealed cable entries, and spark prevention measures — fully compliant with IEC safety standards.

2. Clear Communication, Every Time

In high-noise industrial environments, clarity is everything. This explosion-proof model integrates a high-sensitivity handset and advanced digital noise suppression technology, ensuring crystal-clear audio performance even when ambient noise levels exceed 90 dB.

Supporting both analog (PSTN) and VoIP SIP protocols, the telephone provides flexible integration with various communication infrastructures. Built-in remote management, health monitoring, and self-diagnostic capabilities allow technical teams to perform maintenance efficiently and minimize downtime.

3. Industrial Design with Attention to Every Detail

From structure to user interface, every feature of the telephone has been refined to meet industrial-grade expectations:

• Completely sealed and corrosion-resistant body, designed for harsh and humid conditions;

• Vandal-resistant handset with stainless-steel armored cord, engineered for mechanical strength and durability;

• Heavy-duty rubber keypad with programmable memory buttons for quick access to emergency contacts or control centers.

These features make the telephone not only robust and reliable but also ideal for continuous 24/7 operation in demanding work environments.

4. Flexible and Smart Customization Options

To serve diverse project requirements, the Aluminum Alloy Explosion-Proof Telephone can be tailored with a range of optional features, such as:

• Flashing beacon and high-decibel ringer for visual and audible alerts;

• PA/Intercom system compatibility, enabling seamless connection to site-wide paging systems;

• Call recording and monitoring for centralized supervision and quality control;

• Keypad-free emergency version, perfect for hotline or SOS applications.

This modular design makes it suitable for oil & gas, petrochemical, marine, mining, power generation, railway tunnels, and offshore wind farms, among other critical industries.

5. A Commitment to Safer, Smarter Communication

The launch of the new Aluminum Alloy Explosion-Proof Telephone reflects J&R Technology’s continuous commitment to innovation, reliability, and safety. Each unit is more than just a communication device — it’s a vital link that keeps workers connected and protected in the most demanding environments.

By combining robust materials, certified explosion-proof design, and intelligent functionality, J&R ensures that every call — whether routine or emergency — is heard loud and clear, even in the most extreme conditions.
