Coolant temperatures of 5 degrees above the plant cooling “water” are possible with a liquid-to-liquid type system. The most common intermediate heat exchangers are either plate and frame or shell and tube type. Fouling of the intermediate heat exchanger will likely happen on the well-water side, however, if the intermediate heat exchanger is selected properly it can be taken apart easily and cleaned. The heat is exchanged through the intermediate heat exchanger without fouling the heat exchanger/s. It uses the well water on one side of an intermediate heat exchanger and a coolant such as glycol and water on the other side of the intermediate heat exchanger in a closed loop to cool the compressor. For example: you have well water available but you do not want to put the well water through your new compressor because the water quality is very poor (lots of dissolved solids like iron and calcium etc.), and you have had trouble with the well water fouling your heat exchanger/s in the past.Ī liquid-to-liquid cooling system is an ideal fit for this situation. In this type of system your plant has an abundance of some type of cooling liquid already available but you do not want to provide this coolant to the compressor. The simplest of these systems is a liquid-to-liquid cooling system. Closed-loop dry system with trim cooling.There are six basic types of liquid cooling systems: This article was written to identify the different types of cooling systems and identify their strengths and weaknesses so that you can make an informed choice based on your needs. Each one has its strengths and weaknesses. If you have any questions about any of the ingredients in coolant, you know where to find us.There are six basic types of cooling systems that you can choose from to meet the cooling needs of your load. This post does a good job explaining why. It’s important to note here that you should never mix different coolants together. Some of the most common coolant colors include: Each color represents a certain type of coolant. Coolant always starts off colorless, but then the manufacturer adds dye to it. Have you noticed that coolant comes in many different colors? There’s a reason for that. Silicates (which protects aluminum from rust).Phosphates (which protects iron from rust).The manufacturer’s own blend of chemicals that protect engine components (like the water pump) from rust and corrosion:.More than 90% ethylene glycol (in most cases, depending on the manufacturer).The composition of antifreeze is as follows: In other words, antifreeze makes it possible for the coolant to not freeze at freezing temperatures, and not dissipate into steam at hot temperatures. Coolant contains antifreeze because it lowers the coolant’s freezing point and increases its boiling point. AntifreezeĪntifreeze is another name for ethylene glycol. ![]()
