In recent years, the issue of enterprise safety production has attracted great attention from the state and extensive attention from all walks of life. Especially for petroleum, chemical, coal, medicine, food processing and other industries, “talk about explosive color change” – once an explosion occurs, it will bring casualties, economic losses, chemical raw material leakage pollution and other catastrophic consequences.

Any place that may involve the production, processing, handling, storage, transportation and so on of explosive substances may form an explosive environment. Among them, the frequency converter is the core electrical equipment in industrial production, and its explosion-proof function builds a solid safety bottom line for production.

On November 16, TUV SUD (hereinafter referred to as “TUV SUD”), the world’s leading third-party testing and certification body, awarded Huichuan Technology the “Functional Safety Certificate” and “CE-ATEX Certificate for Functional Safety Devices Associated with Explosive Environments” for the MD580 high-performance engineering inverter.

Mr. Song Lei, Industrial Automation Business Manager, TUV SUD Products Department, Mr. Ing Kristof De Gersem, Explosion-proof Service Manager, Yu Qingbo, Director of Complete machine Engineering Center of Huichuan Technology R&D Department, Yang Yongbing, manager of frequency conversion Product Development Department of R&D Department, Yao Mingying, general manager of chemical industry, Guo Guangdong, senior manager of marketing operation and other representatives of both sides attended the certification ceremony held in Huichuan Technology Suzhou exhibition Hall.

During the certification ceremony, the two sides conducted cordial and friendly exchanges on the current development overview of their respective companies, business scope and future development direction of related industries, international regulations and technical standards.

The MD580 series inverter certified by Huichuan Technology adopts a new generation of platform technology, which has the advantages of safety protection, stability and reliability, powerful function and easy to use compared with traditional drive and control devices. After the joint evaluation of TUV SUD Chinese and German experts, the MD580 series inverter meets the requirements of SIL3 and PLe functional safety levels, successfully obtained the TUV Sud functional safety certification, and passed the explosion-proof test with excellent results, fully meeting the CE-ATEX (Use of equipment and protection systems in potentially explosive environments) directive. The acquisition of the safety certification can meet the special application of 380V/690V in chemical and coal industries, reflecting Huichuan’s technical attains in the field of special, specialized and refined industries.

In the future, Huichuan Technology will rely on the strong support and technical support of TUV SUD’s expert team, based on the agreement of the existing strategic cooperation framework, and continue to deepen cooperation in industrial control, explosion-proof, new energy and other fields. TUV SUD will rely on rich project experience in the field of explosion protection, and professional global technical team, and continue to deepen cooperation with Huichuan Technology to jointly protect the industrial field explosion protection safety.

CE-ATEX certification for explosion-proof equipment

ATEX certification, which stands for “Equipment and Protection Systems for Use in Potentially Explosive Environments”, is a directive issued by the European Union to ensure that equipment and protection systems in potentially explosive environments meet specific safety requirements. Potentially explosive environments include flammable gases, vapors, dust and other environments, and equipment in these environments must be assessed for conformity and affixed with the CE mark before entering the European market.

· Combustible gas environment: a place where flammable gases or vapors may exist. Such as petroleum refining plants, chemical plants, oil drilling platforms, etc.;

· Combustible dust environment: including places where combustible dust may exist. Such as flour processing plants, wood processing plants, agricultural grain storage warehouses, etc.;

· Combustible vapor environment: a place where flammable vapor exists. Such as steam power plant, boiler room, etc.

Application examples:

Taking chemical plants as an example, they are generally divided into explosion-proof areas and non-explosion-proof areas. The inverter is located in the non-explosion-proof area, and the motor is located in the explosion-proof area, the motor overheating is easy to lead to risks, the MD580 series inverter with the HSMT-10 explosion-proof card can be protected in time when the motor is overheating, disconnect the power supply in the specified time (such as the disconnect time defined by the increase safety motor), stop the motor from working, and prevent the risk of overheating.
