Low Temperature Water Cooled Glycol Chillers

 

Low-temperature water-cooled glycol chiller is a cooling device designed for low-temperature environments. It uses glycol as a coolant to achieve a lower operating temperature than pure water. The addition of glycol not only lowers the freezing point of the coolant, but also increases the boiling point, allowing the system to operate stably over a wider temperature range.

Features of low-temperature water-cooled glycol chiller:

1. Low-temperature performance: The glycol mixture can make the chiller’s operating temperature as low as -40°C or even lower, suitable for demanding low-temperature cooling processes.

2. Antifreeze protection: The antifreeze property of glycol effectively prevents the system from freezing in low-temperature environments, protecting pipes and equipment from damage.

3. Corrosion inhibition: The right amount of additives can reduce the corrosion of glycol to metal parts and extend the life of the chiller and circulation system.

4. Thermal stability: The increased boiling point reduces evaporation losses, making it suitable for operation in high-temperature environments, ensuring cooling efficiency and system safety.

5. Economical: Although the initial investment and operating costs are relatively increased due to the use of ethylene glycol, in the long run, its maintenance cost is low and the overall cost performance is high.

 

 

Applications of low-temperature water-cooled ethylene glycol chillers:

1. Chemical and pharmaceutical: In chemical reactions and API production, low temperature conditions need to be precisely controlled to promote specific chemical reactions or maintain product stability.

2. Plastic and rubber industry: During injection molding and extrusion molding, low-temperature ethylene glycol chillers can effectively cool molds, improve production efficiency and product quality.

3. Metal processing: such as cutting fluid cooling of CNC machine tools and thermal management of welding equipment to maintain stable equipment operation and extend tool life.

4. Food processing: In ice cream manufacturing and quick-frozen food production lines, low-temperature ethylene glycol chillers ensure rapid freezing and maintain food freshness and texture.

5. Laser and electronic equipment: Provide constant low-temperature cooling for high-power lasers and semiconductor manufacturing equipment to prevent equipment overheating and ensure accuracy and performance.

In summary, low-temperature water-cooled glycol chillers play an important role in many industrial fields with their excellent low-temperature performance and wide range of applications. If you are considering choosing a low-temperature glycol chiller for a specific application, it is recommended to communicate with a professional supplier to determine the most suitable configuration and specifications based on the actual working conditions to achieve the best cooling effect and economic benefits.
