The presence of propylene glycol in chillers and air conditioners is essential as an important factor. They produce glycol cooling systems for a variety of industries, from food and beverage processing to ice rinks. Glycol chillers are industrial refrigeration systems that use a type of antifreeze called glycol, mixed with water, to reduce the freezing point of a cooling system. Glycol is a group of organic compounds that belong to the family of alcohols. When glycol is mixed with water and pumped through the pipes of the cooling system, it reduces the rate of freezing. This helps maintain temperature stability in the application. Some glycol products, such as propylene glycol, also work to prevent corrosion and bacterial growth in the pipes of the cold system.
Propylene glycol has a lower level of toxicity and is considered a food grade antifreeze. This type of glycol is safer to control than ethylene and can be easily disposed of. Propylene glycol is commonly used in the food industry or in industrial refrigeration systems where people may come into contact with liquid. Propylene glycol can also be more viscous than ethylene, even if used at very low temperatures and has little effect on heat exchange rates. It is important to note that you should never mix different types or brands of glycols together, as this will cause the product to shrink and clog the filters in the refrigeration system. Potentially cause problems with heat transfer and fluid flow Applications of monopropylene glycol.
Propylene glycol in chillers and air conditioners must be mixed with water for proper functioning. The type and amount of water used are key factors that must be considered. Each glycol chiller has its own set of manufacturer recommendations for the best type of water to use in that system. Although municipal tap water may be acceptable at first, it is almost never recommended that non-ionized water be stored for long periods of time. Because it can adversely affect certain metals in the chiller. Calculating the proper ratio of glycol to water in your cooling system depends on the coldest temperature that the glycol solution reaches during operation. If an indoor cooling system is used where there is no opportunity for freezing, the amount of glycol required is significantly less than the requirement of a glycol chiller used outdoors and the temperature is subject to freezing. Also, if a program needs to work at very low temperatures, it should use a glycol mixture similar to the outdoor system. In a cooling system, this temperature is typically the saturated suction temperature in the evaporator, and typically 10 degrees Fahrenheit below the set temperature of the chiller. It is important to use the right ratio of glycol and water in the cooling system.
Propylene glycol antifreezes are high performance and inhibit heat transfer fluid. They are low in toxicity, making them an ideal choice for use in industrial, commercial or agricultural food processing applications.
Propylene glycol is commonly used in food processing facilities or other areas where contaminated drinking water or food may be contaminated.
Antifreeze propylene glycol chiller is essential in any cooling system that is exposed to ambient temperatures below 7 ° C. Having glycol inside the chiller, air blast cooler or adiabatic cooler system protects your equipment from damage.
Low freezing points of glycol mixtures make them ideal for cooling devices below the freezing point of water. Therefore, glycol and water mixtures are often used to cool freezers and similar environments.
The low temperatures associated with glycol mixtures make them useful for applications where a chiller must transfer large amounts of heat quickly. Heat is a by-product of many chemical reactions.
The ability of glycol to transfer heat quickly makes it useful for maintaining the temperature of chemical reactions. For this reason, mixtures of propylene glycol and water are often used to cool fermentations in breweries. It is very important that you regularly monitor the glycol level in your chiller system to ensure maximum efficiency and level of protection. Maintaining a glycol chiller level is part of a chiller maintenance prevention program.
Propylene glycol is stored and transported in stainless steel or mild steel tanks and can be transported by tank trucks. This material is not classified as dangerous for any type of transport and is not dangerous to health. Its flash point is 103 degrees Celsius and its specific gravity is 1.04.
