Shenzhen, China – [August 4, 2025] — Caltta Technologies, a leading provider of mission-critical communication solutions, has successfully delivered a customized private wireless communication system for the Lanzhou Petrochemical National Oil Reserve Base, significantly improving the facility’s hazard management and emergency response capabilities.

As part of China’s Phase II National Oil Reserve initiative, the Lanzhou Petrochemical QCGC project is a key component of the country’s strategic energy infrastructure. The site comprises 30 floating-roof storage tanks with a total capacity of 3 million cubic meters, supported by auxiliary systems for instrumentation, communications, water supply, drainage, and fire protection.

With the increasing operational lifespan of the facility and evolving regulatory standards for hazardous chemicals and major hazard sources, the demand for a safer and more reliable communication system has grown. Caltta, in collaboration with its partner Shandong Jiangke IT, provided a tailored private network solution designed to meet these heightened safety and operational requirements.

Seamless PMR Coverage – No Blind Spots
Caltta deployed a new digital two-way radio system using the facility’s existing communication tower infrastructure. This ensures uninterrupted private network signal coverage across the entire site, enabling staff to communicate in real-time from any location, improving situational awareness and emergency responsiveness.

Explosion-Proof Radios – Safe Operation in Hazardous Environments
The solution includes professional-grade explosion-proof radios (certified to Ex ib IIB T4 Gb / Ex ib IIIC T130℃ Db standards), capable of operating safely and stably in high-risk petrochemical zones. These radios ensure secure communications for front-line personnel under challenging conditions.

Wired-Wireless Interconnection – Smarter, Unified Dispatch
By integrating the wireless communication system with a soft-switch platform, Caltta enabled seamless interoperability between radios, dispatch consoles, and office PBX systems. This unified command and control structure facilitates efficient coordination between field operations and management teams.

With the deployment of a wide-coverage, fast-response, and agile dispatch private network, the Lanzhou Petrochemical reserve base has significantly strengthened its communication infrastructure—providing a solid foundation for risk mitigation, hazard monitoring, and emergency management.
