Chengdu Factory & Office
Deyang Factory
Adapting advanced gas monitoring architectures to the Pacific Northwest's unique climate, maritime industries, and strict local fire compliance standards.
Seattle’s maritime terminal operations, port facilities, and vessel maintenance shipyards require corrosion-proof, salt-spray-resistant fixed gas detectors. Our explosion-proof and high-IP-rated models prevent combustible and toxic gas build-up in wet bilge spaces, cargo holds, and engine rooms.
The concentration of large technology offices, high-density server environments, and commercial real estate hubs in Seattle demands extensive HVAC integration. Fixed CO and refrigerant gas detectors safeguard parking garages and modern utility rooms, feeding directly into local Building Management Systems (BMS).
Seattle’s thriving craft brewery sector and proximity to agricultural transport hubs necessitate precise Carbon Dioxide (CO2) and Ammonia (NH3) detection. Leakage in cold-storage units or beverage carbonation systems poses severe asphyxiation risks; our fixed monitors protect employees in confined working spaces.
The Seattle Fire Department (SFD) enforces rigid protocols based on the International Fire Code (IFC) and National Fire Protection Association (NFPA) standards, specifically NFPA 72 (National Fire Alarm and Signaling Code) and NFPA 55 (Compressed Gases and Cryogenic Fluids Code).
Under the Seattle Fire Code Chapter 53, facilities storing carbon dioxide systems with more than 100 pounds of CO2 must install a continuous gas detection system. The system must trigger an audible and visible alarm inside the room when levels reach 5,000 ppm (OSHA PEL limit), and shut off the source flow to protect personnel from odorless hazards.
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 as CE, 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.
Pioneering smarter sensor matrices and seamless connectivity protocols for next-generation smart cities and factories.
Transitioning towards NDIR (Non-Dispersive Infrared) and MEMS-based semiconductor technology. These sensors yield multi-gas detection capabilities from a single chip with zero drift, lower power draws, and lifespans exceeding 10 years without requiring replacement.
Integrating LoRaWAN, NB-IoT, and 5G cellular communication channels into standard detector modules. Our cloud dashboard facilitates real-time predictive analytics, remote calibration sweeps, and automatic warning dispatches to mobile safety crews.
Utilizing machine learning models built into control panels to analyze trace fluctuations in ambient gas profiles. By distinguishing between normal operational variations and real leaks, false alarms are decreased by up to 90%.
Combining world-class production capacity in Chengdu & Deyang with localized engineering support for maximum reliability and cost control.
Our strategically developed production lines leverage southwestern China’s industrial ecosystem, ensuring material security and manufacturing continuity.
A twenty-year timeline of technological breakthroughs and market expansions, driving toward safer global environments.
