Most Important Things To Know About Glycol Chillers

Chillers are used by many different types of industries. A glycol chiller is one of the more popular ones when it comes to industrial refrigeration systems. This type of chiller uses a type of antifreeze called glycol which helps lower the freezing point making the chiller system more efficient. Glycol is an odourless and colourless liquid that is highly viscous. It is mixed with water and pumped through the pipes of the chiller system. This effectively reduces the freezing temperature and helps maintain the temperature consistency.

Many industries require such cooling units and these types of chillers are available in numerous variants. A glycol chiller is highly effective since it helps reduce the freezing point and it also boosts the antifreeze property too. Glycol is usually used in a ratio of 60/40 with water and assists with the process of rapid cooling. Thus, this can effectively cool the system and also ensure there is no coolant frozen in the pipes.

Common Applications of a Glycol Chiller

Chiller and cooling units are used by many different types of industries. The cooling requirements tend to vary depending on what needs to be kept cool. It is used for various applications like dairy, viticulture, aquaculture, brewery, cool rooms manufacturing industry, as well as for domestic and commercial air conditioning. Glycol chillers are also used in brewery, distillery, and fermentation since this industry has a high demand for chillers. One of the other industries that have a  high demand for chillers includes the dairy industry.

Important Facts

  • A Glycol chiller is an industrial refrigeration system that uses a type of antifreeze (glycol) to lower the freezing point of a chiller system.
  • Glycol is an odourless and colourless liquid.
  • There are two types of glycol like ethylene and propylene.
  • Glycol is highly effective in maintaining temperature consistency as well as preventing corrosion and bacterial growth in the chilling pipes.
  • The ratio of glycol to water depends on the coldest temperature the glycol solution reaches.

How is it Different from a Water Chiller? 

The way a chiller works is when the cooling medium interfaces with the equipment and absorbs the thermal energy in the process. This is an essential heat exchange that effectively helps lower the temperature of the chiller and maintain it as well. Glycol and water are two popular coolants used in chillers. The water chillers are less expensive and are useful in a cooling unit. On the other hand, glycol will also ensure resistance to corrosion and act as an antifreeze. Since glycol helps lower the freezing point is more effective as compared to the water chiller.

The way a water chiller works is that heat transmission occurs between various mediums like fluid and solid. There is either heat absorption or vapour compression where the piping system is used to circulate the chilled coolant that is water. The glycol chiller consists of a coolant that is a mixture of both glycol and water and is channelled through the pipes to effectively result in a thermal exchange. This is a good way to absorb heat and the warm coolant is returned to the cooling unit through the piping system.

Tips to Maintain your Chiller

A cooling unit is used by many different industries and is an important investment. This is not something one buys regularly; it is a long-term investment hence it is a good idea to put some thought into this prior to buying one. There are many firms providing refrigeration solutions including that for chillers, air conditioning, like Kyabram Refrigeration. However, it is necessary to inspect and clean to remove the build-up of dirt, oil, and other debris. It is also necessary to clean the air filter, check the water quality and glycol mixture, inspect the fluid system for leaks or loose pipes and check the plumping. Make sure to also check the voltage and inspect the mechanical components for signs of wear or overheating.
