Chengdu Factory & Office
Deyang Factory
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," member of the China Fire Protection Association, and 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.
Unveiling the technological transitions driving the next-generation gas hazard monitoring infrastructure.
Modern plants are replacing expensive armored cabling with low-power wireless intelligent terminals. Utilising NB-IoT, LoraWAN, and Zigbee allows immediate hot-swapping and flexible point density without heavy physical infrastructure investments.
Traditional electrochemical and catalytic bead sensors suffer from zero drift and atmospheric interference. Advanced gas safety controllers now integrate ML algorithms to automatically recalibrate based on temperature, humidity, and history.
For highly volatile organic compounds (VOCs) and toxic compounds like Hydrogen Sulfide or Carbon Monoxide, PID and Non-Dispersive Infrared (NDIR) sensors are replacing traditional systems due to their 5+ year lifespans and chemical immunity.
Implementing targeted safety control networks designed for specialized operations, hazard zones, and compliance frameworks.
Highly toxic (H2S, CO) and highly flammable hydrocarbon vapors require robust flameproof gas detectors (GTYQ-AT0503/d) paired with SIL-rated controllers. Systems automatically close emergency gas solenoid valves (CT-XF5 series) in milliseconds to prevent catastrophic chain reactions.
With the rise of underground facilities and dense parking networks, CO buildup presents critical safety challenges. The OEM AT2004BIV-CO Carbon Monoxide Gas Detector integrates seamlessly with ventilation automation through low-voltage distribution nodes to keep levels safe.
Battery thermal runaway generates toxic gas combinations (CO, H2, HF). Our high-precision electrochemical and VOC gas detection models identify early outgassing stages, alerting controllers before visible combustion begins.
Leveraging domestic gas alarms like the JT-AT2006, residential high-rises utilize networked bus monitoring architectures. These systems allow facility managers to monitor gas safety status in real time and automatically shut off solenoid valves in the event of a leak.
Over two decades of evolution from a local component developer to an international safety technology manufacturer.
Startup Phase: Established April 17, 2003. Launched our first-generation gas leakage alarms and fire fighting accessories, forming the foundation of our early safety portfolio.
Initial Scale & Valve Focus: Initiated production of specialized gas safety solenoid valves. Expanded local OEM services and relocated our headquarters to Longtan Industrial Park.
Rapid Growth: Achieved the milestone of 10 million units in cumulative gas detector sales. Established our main Chengdu factory and rolled out fire power monitoring solutions.
IoT Platform Rollout: Launched our proprietary gas safety IoT cloud. Developed fire alarms, emergency evacuation indicators, and became a registered supplier to China's top 5 gas providers.
Industrial Divisions: Began construction on our Deyang production hub. Established the specialized Petrochemical and International Business divisions to meet global standards.
Global Expansion & AI: Completed the Deyang factory expansion. Rolled out our wireless intelligent gas monitoring network, AI-assisted safety valves, and next-generation urban pipeline systems.
Aligning global supply chains with high-level certifications, specialized OEM/ODM capabilities, and long-term hardware reliability.
Procuring gas safety equipment for heavy industry demands adherence to regional compliance protocols. Xinhaosi ensures its detectors undergo testing for CE, SIL, and CPA certification to confirm reliability and explosion-proof safety in demanding environments.
Our CNAS-accredited calibration laboratories operate in accordance with ISO/IEC 17025. This structure guarantees traceable calibration reports accepted by regulatory and safety inspectors globally, streamlining your system approvals.
