Where can ethylene glycol chillers be used?

As a high-efficiency refrigeration equipment, ethylene glycol chillers play an important role in the industrial and commercial fields due to the low-temperature anti-freezing properties of ethylene glycol solution. Its main working principle is to use ethylene glycol aqueous solution as a coolant, absorb heat in the evaporator, and then circulate to the terminal equipment to release cold, thereby achieving stable temperature control. This system has the characteristics of strong adaptability to low-temperature conditions and excellent antifreeze performance, making it the preferred solution for scenes requiring precise temperature control.

In the field of industrial production, ethylene glycol chillers are widely used in process cooling of chemical synthesis, biopharmaceuticals and other processes. For example, during the polymerization reaction, the reaction heat needs to be continuously removed. The ethylene glycol unit can provide a stable cold source of -5℃ to -10℃ to ensure that the reaction system is in the optimal temperature range. For the matching of pharmaceutical freeze dryers, its deep cooling capacity below -40℃ can meet the strict requirements of the freeze-drying process for ultra-low temperatures. In the precision machining process, the ethylene glycol circulation system is used for CNC machine tool spindle cooling, which can effectively control machining thermal deformation and improve part machining accuracy.

The food cold chain industry also relies on the technical advantages of glycol chillers. The dairy fermentation workshop uses glycol chillers to maintain a constant temperature environment of 6-8℃ to ensure the activity of the bacterial flora and the quality of fermentation. The cold storage quick freezing room adopts a direct expansion glycol system, which can not only achieve rapid freezing at -35℃, but also avoid the risk of leakage of the traditional Freon system. The temperature curve of the fermentation tank is accurately controlled in the brewing process to ensure the perfect formation of different wine flavor substances.

The energy-saving value of glycol chillers is reflected in the commercial building field. The glycol solution in the ice storage system is used as a cold storage medium, and the peak and valley electricity price policy can reduce the air conditioning energy consumption by more than 30%. The data center adopts an ethylene glycol natural cooling system, which uses outdoor cold sources to provide free cooling through plate exchange in winter, greatly reducing the operation time of the refrigeration unit. This diversified application scenario fully demonstrates the professional value and engineering adaptability of glycol chillers in the field of temperature control.
