Explosion-proof chiller refers to the refrigeration equipment designed for flammable and explosive environments, which not only has the refrigeration function of an ordinary chiller, but also ensures safe operation in hazardous places through triple explosion-proof design. Specifically, the explosion-proof chiller includes:
- Electrical system: adopts Exd explosion-proof motor and intrinsically safe control cabinet to ensure electrical safety, certified by EN 60079-1.
- Mechanical protection: designed with fully enclosed impeller, high precision bearing temperature monitoring to prevent friction sparks.
- Structural Strengthening: using 316L stainless steel shell and adding nano-coating, acid and alkali corrosion resistance, protection level up to IP66/IP67.
In addition, the explosion-proof chiller is equipped with an intelligent control system, including multi-stage safety interlock and remote monitoring functions, supporting Modbus TCP/IP protocol, which can be integrated into the DCS system to achieve unattended operation. In terms of energy efficiency, it adopts scroll compressor and frequency conversion technology with high energy efficiency ratio, saving 25% energy compared with traditional models, and is equipped with waste heat recovery system to improve the comprehensive energy efficiency ratio.
In terms of application, explosion-proof chiller is suitable for chemical industry, petroleum, pharmaceutical factories, laboratories and other places where there are flammable and explosive factors, which is an indispensable safety and security equipment in the production process of these industries. When choosing an explosion-proof chiller, factors such as explosion-proof level, refrigerant compatibility, protection level and energy efficiency optimisation need to be considered to ensure the reliability and efficiency of the equipment.
Explosion-proof chillers are widely used in a number of industries with strict safety requirements due to their special design and safety, including:
- Chemical and petroleum industries: In chemical production, especially when dealing with flammable and explosive substances, explosion-proof chillers are used to control the temperature of reaction kettles to prevent accidents caused by uncontrolled temperature rise. Similarly, in the oil refining process, it is ensured that the cooling system does not become a safety hazard.
- Pharmaceutical industry: In the pharmaceutical process, the need to accurately control the temperature of the fermentation process, explosion-proof chiller can meet these strict requirements to ensure production safety and drug quality.
- Food industry: In food processing, rapid refrigeration to comply with packaging requirements or to control the fermentation process, especially in environments where any potential risk of explosion needs to be avoided.
- Electronic Manufacturing: in the production of precision electronic components, explosion-proof chillers are used to cool equipment and prevent damage caused by overheating, especially when dealing with sensitive electronic components.
- Laser and CNC machinery field: to provide stable cooling for laser equipment and CNC machine tools to ensure processing accuracy and equipment life, especially in the processing environment of flammable materials.
- Electroplating & Ultrasonic Cleaning: In these industries, temperature control is used to improve plating quality and cleaning efficiency while ensuring operational safety.
- Energy & Mining: such as oil and gas extraction, coal mining, etc. These environments are often at risk of explosions and explosion-proof chillers are essential cooling equipment.
- Special materials processing: processing of plastics, rubber, paint and other materials, cooling is required to control the chemical reaction, while ensuring the safety of the operating environment.
In summary, explosion-proof chiller because of its unique safety features, is widely used in the need to strictly control the temperature and there is a potential risk of explosion in the industrial sector, to ensure that the production process is both efficient and safe.
