2. Air cooled industrial glycol chiller applications
Glycol chillers are specialized refrigeration systems, and often involves the use of antifreeze. A popular application is in beverage production, wherein the food grade chemical propylene glycol is used. Propylene glycol plays a significant role in the application of a glycol chiller. For cooling in brewing, there are few processes where decreasing or maintaining temperature are important - like crash cooling a beer after fermentation, or keeping a steady temperature during fermentation (which generates heat), or cooling the wort after an initial boiling process.

4. Eurostars air cooled industrial chiller protection devices
(1)Motor overload protection
Including for compressor motors, water pump motors and fan motors.
There are some situations that will cause damage to motors in an industrial chiller, such as instable voltage, ambient temperature too high which mostly caused by poor ventilation, returning water temperature too high, etc. In these cases the motor running current will get higher than its safe range, which might damage the motor if keep it working. Built in protection for overload will shut down the chiller and warn you if the motors are working unhealthily.
(2)Compressor motor overheat protection
Compressor is the heart of an industrial chiller, it reflects problem of the whole chiller unit. The situation causes compressor motor overheat includes poor ventilation, dusty condenser, refrigerant circuit blocking, lack of refrigerant, etc.
This alarm reminds you to check through the chiller unit, prevent it from burning out because of unhealthy working condition. 
(3)Discharge temperature overhigh protection
Discharge temperature overhigh normally caused by high suction temperature, high compressor motor temperature, lack of refrigerant, etc. It works as supplementary of compressor motor overheat.
(4)High&low pressure protection
High pressure normally caused by poor ventilation, dusty condenser, refrigerant circuit blocking, etc.
Low temperature caused by lack of refrigerant, system blocking and so on.
(5)Returning water overheat protection
Chiller supply cold water to cool the production process, normally the returning water temperature will be 3ºC to 8ºC higher than supplied water. If the chiller is not creating cooling energy, or the chiller capacity is not enough for the application, the temperature in the circuit will get higher and higher. This will cause damage for the production even the equipment.
While a chiller got an alarm function for returning water temperature, we can learn the situation promptly and make reaction.
(6)Low water flow/level protection
For a chiller with no open-circuit water tank, there will be a water flow switch to make sure the water circuit is working, preventing both production process and chiller unit from harmed by circuit blocking or water leaking.
(7)Phase protection
If an industrial chiller was falsely wired, motors will revert, which is a serious problem for all the motors. Phase protection will remind you to connect the power in a right way.
(8)Anti-freezing protection
This function prevents the water in the circuit from freezing, so to make sure the cooling circuit working in a healthy condition.

7. What concentration of glycol is needed for freeze protection?
Glycol must be used in applications where the chiller is installed outdoors or when fluid temperatures below freezing are required. The freezing point of the water-glycol solution depends on the type and concentration of glycol, and whether or not the glycol contains inhibitors for corrosion protection. The table below provides a rough guide of the ethylene glycol concentration required for various ambient or operating temperatures. Choose a glycol concentration that results in a freezing point of several degrees below the lowest anticipated ambient or operating temperature.

8. FAQ about glycol for industrial chiller
Glycol is a very important element in any cooling system. Despite its ubiquity and its importance, most customers don't fully understand all that it does. In an effort to clear up some of the confusion about glycol, here are our answers to the most commonly asked questions.

Q: What is Glycol?
A: Glycol is a water-miscible organic compound in the alcohol family. It is commonly used for cooling in industrial and mechanical applications. Glycol is sometimes called antifreeze or a coolant. Though it acts similarly to a refrigerant, and someone may refer to glycol as a refrigerant, this statement is incorrect. Glycol cools solely through heat transfer in an exchanger; whereas, refrigerant uses an evaporation-condensation cycle to remove heat.

Q: What does glycol do in a processing cooling system?
A: The most important role glycol plays in a process cooling system is to adjust the temperature range of the system. Without any glycol in the system, the water will freeze at the normal 32°F (0°C). In this case, the system ambient temperature can never go below this temperature. However, many systems need temperature flexibility as pipes travel outside and into unheated areas. Adding glycol to the water lowers the freezing point. The percent of glycol determines what the new freezing point will be.

A lower freezing point means process fluid can be kept at colder temperatures. A greater difference between medium temperatures allows for a faster heat transfer process. Heat always travels in the direction of higher temperature to lower temperature. When a coolant with a colder temperature is used, more of the energy can be transferred from the other fluid or process to the coolant.

Q: What are the benefits of using glycol in my system?
A: Glycol often contains corrosion inhibitors which can help to prolong the life of components. Its main function is to enable a cooling system to operate at temperatures below the freezing point of water. Certain systems may require this lowered cooling for optimum performance.

Q: What percentage of glycol does my system require?
A: Deciding on the perfect glycol-water mixture is critical to your chiller's operation. You will need to consider factors such as ambient temperature, desired lowered temperature, and heat transfer rate. As there can be adverse effects on the cooling system when using glycol, the glycol concentration should be limited only to what is required for freeze protection.

Q: Are there different types of glycol?
A: Yes. There are two types of glycol commonly used for process chillers: Propylene and Ethylene Glycol. These products vary on metrics such as performance, environmental factors, and general safety. The specific needs of your process will determine which glycol type is best for your system.

Q: Is glycol safe to use around food and beverage products?
A: In general, propylene glycol is considered food grade and can be used in food and beverage operations. Most brewery applications use this type of glycol.
