What is a glycol chiller and how should you choose the best Glycol chiller manufacturers when needed? Before you proceed to get one; understand it first. It is an industrial grade refrigeration system that uses Glycol to lower the freezing point. What makes Glycol the ideal medium? It is a colorless and odorless viscous liquid. When it is mixed with water and pumped in a chilling system through pipes, it slows the freezing rate and maintains the temperature consistency. Glycol also reduces the bacterial growth and corrosion as well. Due to excellent qualities and high efficiency, it is a popular medium. Types of glycols used in the industrial refrigeration systems Two types of glycols are used in the industrial refrigeration systems by Glycol chiller manufacturers; Propylene Glycol and Ethylene Glycol. Both these variants offer excellent protection against corrosion, and the level of freeze protection is also same. They offer growth of bacteria, fungi, and algae as well. Ethylene Glycol It is a sweet-smelled liquid with moderate toxicity. If swallowed, it is harmful. It is the reason, use of Ethylene Glycol is not fit for food processing units, drinking water chillers or any other application where leakage can contaminate food stuff. Since it is relatively cheaper, the use of Ethylene Glycol is quite widespread. Industrial chilling applications where large volumes of coolant are needed, it is a preferred choice. Propylene Glycol It is relatively low toxic and considered as a food grade antifreeze. It is easy to handle and dispose of. Propylene Glycol is widely used in the food industry because it is harmless even if it encounters the edible items. However, due to high viscosity, it is less efficient are very low temperatures as compared to Ethylene Glycol. Glycol chiller manufacturers suggest the appropriate type of chillers depending on the application requirement. What is the ideal ratio of water to glycol? In the industrial refrigeration system, the ratio of water and glycol solution depends on several aspects: • What is the coldest temperature that reaches during the operations? • Is the chilling application used indoors or outdoors? It is important to remember that the proportion plays a critical role in the efficiency of cooling. Adding too much water or too less water makes it inefficient. There is a risk of bursting the pipes or rupturing the chiller evaporator if the glycol is not sufficient. When requirement specifications are given to the manufacturers, they can suggest it right.
