Yingrun Group's online gas detector has obtained another explosion-proof certificate: safety and quality have been upgraded again

In today's industrial production, where safety and efficiency are increasingly pursued, certification of explosion-proof electrical equipment is an important indicator of product reliability and corporate responsibility. On June 30, 2025, Xi'an Yingrun Environmental Protection Technology Group Co., Ltd. (hereinafter referred to as "Yingrun Group") once again received good news that its core product - online gas detector (model specification: ERUN-PG5) - has successfully obtained the explosion-proof certificate issued by the National Low Voltage Explosion proof Electrical Quality Inspection and Testing Center (Liaoning), with certificate number CLEx24.0320. This milestone achievement not only demonstrates the continuous technical strength of Yingrun Group in the field of gas detection, but also marks a new height in the safety performance of its products in harsh industrial environments, providing a more solid safety guarantee for industrial customers.

The explosion-proof certificate awarded this time is a recognition of the excellent explosion-proof performance of the ERON-PG5 online gas detector. This product has obtained dual explosion-proof marks of "Ex db IIC T6 Gb" (gas explosion-proof) and "Ex tb Ⅲ C T80 ℃ Db" (dust explosion-proof), which means it can operate safely and stably in hazardous areas containing explosive gases and combustible dust. This is undoubtedly a crucial safety guarantee for industries with flammable and explosive risks such as petroleum, chemical, metallurgical, power, and pharmaceutical. Yingrun Group always adheres to the concept of "technological innovation, safety first", and is committed to providing customers with high-quality and highly reliable gas detection solutions. The re acquisition of the explosion-proof certificate is a vivid practice of this concept.

Excellent quality under strict standards: compliant with the latest national explosion-proof standards

The ERUN-PG5 online gas detector has passed the explosion-proof certification based on strict review and inspection of product drawings, technical documents, and samples. The National Low Voltage Explosion proof Electrical Quality Inspection and Testing Center (Liaoning), as a domestic authoritative testing institution, has conducted comprehensive evaluations of products based on a series of the latest national standards, ensuring their reliability in complex hazardous environments. These standards include:

★GB/T 3836.1-2021 Explosive Atmosphere Part 1: General Requirements for Equipment：

This standard specifies the general requirements for electrical equipment used in explosive environments and serves as the foundation for the design and manufacture of all explosion-proof electrical equipment. The compliance of ERUN-PG5 indicates that it meets strict safety requirements in terms of structure, materials, and protection level.

★GB/T 3836.2-2021 Explosive Atmosphere Part 2: Equipment Protected by Flameproof Enclosures "d"：

Explosion proof enclosure "d" is a commonly used type of protection in explosion-proof electrical equipment. Its principle is to enclose components that may generate sparks, arcs, or dangerous temperatures in a sturdy enclosure that can withstand the pressure generated by the explosion of internal explosive mixtures and prevent flames from spreading to the explosive environment outside the enclosure. ERUN-PG5 meets this standard, which means that even if there is an explosion inside the device, it will not ignite the external environment, greatly improving the safety of the device.

★GB/T 3836.31-2021 Explosive Atmosphere Part 3: Equipment Protected by Dust Ignition Resistant Enclosures "t"：

With the increasingly prominent risk of dust explosion in industrial production, the "t" protection technology for preventing dust ignition of the shell has become particularly important. This standard ensures that the equipment casing can effectively prevent combustible dust from entering the interior, or even if it enters, it will not be ignited, while limiting the surface temperature of the casing to avoid igniting external dust. ERUN-PG5 has obtained the "Ex tb Ⅲ C T80 ℃ Db" dust explosion-proof mark, indicating that it also has a high level of safety in dusty environments and is suitable for places with combustible dust such as coal mines, grain processing, and wood processing.

Guarding the lifeline of industry: the profound significance of explosion-proof certification and the commitment of Yingrun Group

The acquisition of the explosion-proof certificate is not just a certificate for Yingrun Group, but also a solemn commitment to industrial safety responsibility and a deep empowerment of customer value. In complex industrial production environments, accidents such as gas leaks and dust explosions often cause incalculable casualties and property damage. Therefore, choosing equipment that has undergone strict explosion-proof certification is the key to ensuring production safety and maintaining employee health.

The ERUN-PG5 online gas detector, with its dual explosion-proof certification, can be widely used in the following high-risk scenarios:

▲Petroleum and petrochemical industryRefineries, chemical plants, oil and gas storage and transportation stations, and other places have a wide variety of flammable and explosive gases. ERUN-PG5 can effectively monitor various flammable gases such as methane, propane, and hydrogen, providing real-time safety warnings for the production process.

▲Coal Mining and MiningMethane and coal dust are the two main sources of explosion in coal mines, and the explosion-proof performance of ERUN-PG5 makes it an ideal choice for mine safety monitoring.

▲Fine Chemicals and PharmaceuticalsDuring the production process, volatile organic solvents and flammable chemicals are often involved. ERUN-PG5 can accurately detect leaks and prevent accidents from occurring.

▲Electricity and MetallurgyScenarios such as hydrogen cooled generator sets, coke oven gas, and blast furnace gas have high requirements for gas leak monitoring, and ERUN-PG5 can provide reliable assurance.

▲Food processing and grain storageFlammable dust such as flour, starch, and sugar powder pose an explosion risk at specific concentrations, and the dust explosion prevention function of ERUN-PG5 effectively addresses such challenges.

Yingrun Group is well aware that the vitality of its products lies in their safety and reliability. The ERUN-PG5 gas analyzer has once again obtained the explosion-proof certificate, which not only affirms the quality of the product itself, but also fully recognizes the R&D, production, and quality management system of Yingrun Group. The company always adheres to customer demand orientation, driven by technological innovation, and continuously improves product performance and safety standards. From strict screening of raw materials, to lean control of the production process, to rigorous testing before leaving the factory, every aspect strives for excellence, ensuring that every device delivered to customers has excellent quality and reliable explosion-proof performance.

In the future, Yingrun Group will continue to increase its research and development investment in gas detection technology, actively respond to the national call for safety production and environmental protection, and continuously launch more high-quality explosion-proof products that meet national standards and adapt to complex industrial environments. The company will continue to pay attention to cutting-edge technologies and customer feedback in the industry, and is committed to providing smarter, more accurate, and safer overall solutions for global industrial users, jointly building a safer and more efficient industrial production environment.
