Deyang Intelligent Production Base
Founded in 2003, Xinhaosi is one of the most influential and trusted brands in the global gas safety industry. Over the past two decades, we have steadily built a robust and comprehensive production and service system, which integrates cutting-edge R&D, intelligent manufacturing with advanced automation equipment, digital marketing across global channels, professional after-sales support with an experienced technician team, flexible OEM/ODM services, as well as CNAS-Accredited laboratory calibration services that meet international standards.
Our diversified product portfolio covers industrial & residential gas detection & alarm systems, industrial & household gas solenoid valves, and urban gas pipeline network monitoring systems—all engineered to adapt to complex working environments and strict safety requirements. We produce and sell tens of millions of units annually, catering to a wide range of industries that demand reliable gas detection solutions, including oil & gas exploration and production, petrochemicals, urban gas distribution, automotive manufacturing, pharmaceuticals, new energy, steel production, and beverage processing.
Guided by the core mission of “Making Gas Safety Accessible Everywhere,” we consistently deliver high-performance, reliable products and customized solutions tailored to each client’s unique needs. Every item we manufacture undergoes rigorous quality control tests, and every service we provide is backed by our professional technical team, fully embodying our unwavering commitment to safeguarding gas safety across both industrial workplaces and residential environments, and striving to build a safer world with sustainable gas safety technologies.
Adhering to ISO9001 quality management system standards, Xinhaosi's core products have obtained a full range of authoritative certifications, including national compulsory Products Certification, explosion-proof certification, fire product certification, CPA measurement instrument type approval certificate, and international approvals such as CE and SIL. Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise", "National Quality Leading Enterprise in the Gas Alarm Industry," membership in the China Fire Protection Association, and serves as the main drafting organization for the national standard of solenoid valves, further confirming its industry influence and reputation.
In the field of intellectual property, Xinhaosi has built a robust innovation system with over 50 patents and software copyrights. These patents cover core technological areas, including a graphical monitoring system for gas detection and alarm, which enables predictive maintenance based on historical data to reduce equipment failure rates by over 30%, and a solenoid valve with flow monitoring functionality that integrates flow detection and alarm capabilities. The company also pioneered China's first networked bus-type gas leakage monitoring system and the only maximum-point gas leakage monitoring system certified by the Ministry of Public Security, demonstrating its leading position in cutting-edge technological research.
Our in-house laboratory is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), recognized both domestically and internationally under the ILAC-MRA framework. It operates in accordance with ISO/IEC 17025, the international standard for testing and calibration laboratories. It provides reliable and traceable testing services for gas detection and alarm products, solenoid valves, and related safety equipment. Test reports issued by the CNAS-accredited laboratory are widely accepted by regulatory authorities, certification bodies, and customers in China and overseas, helping to ensure product quality, safety compliance, and market access.
Why international procurement leaders rely on our vertically integrated Sichuan production bases for high-reliability gas safety hardware.
By producing gas detection sensor components, intelligent alarm controllers, and solenoid safety valves under one roof, we eliminate intermediate supply chain delays. Our Deyang plant houses state-of-the-art SMT lines, die-casting divisions, and advanced testing setups to guarantee component traceability and strict quality management.
We configure Modbus RTU, BACnet, and wireless LoRaWAN protocols to seamlessly match local Building Management Systems (BMS) in Europe, the Americas, and APAC. Our global dealer network provides engineering consultancies, localized on-site calibration, and rapid troubleshooting to comply with ATEX, CE, and SIL standards.
Located in Sichuan's major industrial manufacturing corridor, we benefit from reliable raw materials, logistics access, and technical labor. This enables us to produce millions of gas alarm systems annually, providing OEM/ODM partners with competitive pricing structures without compromising reliability.
Addressing the strict requirements of modern international procurement: sensor longevity, high-stakes safety integration, and reliable life-cycle support.
Large-scale global buyers face complex integration challenges. Industrial gas detection systems cannot exist as isolated devices; they must actively interface with DCS (Distributed Control Systems), fire alarm networks, and automated safety valves. Our products are engineered with robust galvanically isolated outputs, RS485 communication interfaces, and programmable relay contacts to meet these precise demands.
Furthermore, our intelligent predictive maintenance system actively monitors sensor drift and sensitivity decay. By notifying engineers before failures occur, facilities reduce down-time, ensure continuous safety compliance, and lower the Total Cost of Ownership (TCO) across complex petrochemical facilities, municipal gas networks, and residential estates.
From complex industrial processing plants to urban infrastructure and commercial spaces, we ensure continuous environmental monitoring.
Designed for damp, low-oxygen shafts, our GT-AT0616 and GT-AT0617 series monitor heavy combustible gas build-ups and hazardous leaks, alerting personnel before entering high-risk work environments.
Explosion-proof monitoring systems like the GTYQ-AT0505/d and XP4000P detect toxic VOCs and explosive gases in refineries, utilizing robust aluminum enclosures to withstand extreme temperatures.
Integrated pipeline monitoring keeps city infrastructure secure. Coupled with normally closed industrial solenoid valves, systems immediately shut off main supplies upon detection of dynamic flow drops.
Using our bus-type household detectors (e.g., JT-AT2004BII), multi-family residential complexes benefit from interconnected monitoring systems that coordinate alerts to local safety dispatchers.
A history of innovation, scale expansion, and breakthrough technologies since 2003.
Analyzing the shift from reactive safety systems to predictive, networked, and automated gas control architectures.
Next-gen safety relies on processing sensor data locally. Modern systems deploy edge intelligence directly inside solenoid valves. By continuously analyzing transient pressure variations and flow patterns, smart valves distinguish between standard flow spikes and structural ruptures, initiating shutdowns in milliseconds.
Traditional point-to-point wiring is being replaced by wireless mesh protocols (LoRaWAN, NB-IoT). These technologies permit rapid deployment in remote chemical installations or historic urban centers, with sensor batteries operating reliably for up to 5-10 years on low current draws.
With global sustainability standards tightening, monitoring minor fugitive greenhouse gas emissions (such as methane leaks) has become critical. High-performance NDIR (Non-Dispersive Infrared) sensors with zero drift support enterprises in tracking emissions, helping them align with international green safety initiatives.
