Engineered for seamless integration with industrial detectors, solenoid valves, and safety shut-off systems under strict SRPS and EN compliance standards.
Serbia’s industrial transformation, powered by strategic upgrades in the energy, petrochemical, and automotive sectors, has driven a critical need for advanced, high-reliability gas detection control systems. Major installations like the NIS refinery in Pančevo, the expanding natural gas transmission grids overseen by Srbijagas, and heavy industrial facilities such as the Smederevo Steel Mill demand uncompromising compliance with European safety regulations. As Serbia continues to harmonize its national rules with EU directives, local installations must comply strictly with the Rulebook on equipment and protective systems intended for use in potentially explosive atmospheres (complying with the ATEX Directive 2014/34/EU) and equivalent Serbian standards (SRPS EN series).
This evolving regulatory framework makes the gas detector controller a crucial hub for safety automation. Modern installations must support multi-channel inputs (both analog 4-20mA and digital RS485 Modbus RTU) to interface with explosive-proof gas transmitters monitoring toxic gases (such as H₂S, CO, and SO₂) and combustible hydrocarbons (CH₄). Furthermore, integration with automatic safety valves is essential to isolate pipeline systems instantly when a gas leakage is detected, preventing catastrophic explosive events and safeguarding regional worker health.
Serbian municipal and commercial structures, including district heating systems in Belgrade and Novi Sad, require centralized gas monitoring hubs that can run 24/7 in harsh continental climates. Our controller range delivers uninterrupted signal processing from -40°C to +70°C, ensuring flawless operations even during winter sub-zero drops. Direct linkage with safety shut-off systems reduces operational downtime and fulfills insurance audits required by Serbian municipal safety offices.

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 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.
Our safety architectures are engineered to support key localized application profiles across Serbia’s primary commercial and industrial segments.
Designed for NIS Pančevo Refinery. Incorporates redundant CAN bus and RS485 communication protocols, supporting long-distance signal transmission from processing units to centralized security rooms without signal attenuation.
Perfect for heavy manufacturing in Smederevo. Provides reliable protection against carbon monoxide (CO) leakage, combining audible-visual alarms (like BJX-24E) with high-integrity controller shut-down switches.
Ensuring district heating safety across Belgrade municipal zones. Our intelligent control systems tie gas leakage alarms to emergency gas shut-off solenoid valves to guarantee immediate residential area isolation.
As a leading gas safety equipment developer, Xinhaosi operates two advanced factories in Chengdu and Deyang. This dual-factory configuration enables unparalleled production stability, allowing us to manage large-scale global shipments easily. Serbian EPC contractors and security distributors benefit from our robust vertical integration—from PCB assembly and automated SMT production lines to CNAS testing and calibration labs.
By leveraging the reliable logistics infrastructure of the China-Europe Railway Express (Kolasin-Belgrade connections) and direct shipping channels, we offer highly predictable delivery times to Serbia. Our dedicated OEM/ODM division offers custom silk-screen branding, Serbian language localized UI interfaces, tailored mounting options, and custom relay configuration configurations tailored for local standards.
Our solutions deliver advanced hardware capabilities combined with significant cost advantages. This translates to 30% to 45% capital savings compared to Western European alternatives, without compromising safety certifications or critical regulatory requirements.
