Precise Temperature Control Industrial Cooling System
Thailand is located in a tropical area. The weather is hot all year round. In the use of machinery, electronic equipment and other devices in industrial plants, when the temperature increases, the inside of the machine will overheat, resulting in equipment damage, inefficient operation and if the heat accumulates more and more, it may cause a fire. The heat in the machine is like the heat in a person's body. When our body temperature is higher than normal, we will get sick and will not be able to do things efficiently. Therefore, we take into account the maintenance of the machine and can solve the problem of high temperature machines by: Chiller Be a helper
Thailand is located in the tropical zone. It is hot all year round. In machine operation Electronic device and other industrial equipment when there is an increase in temperature causing the inside of the machine to overheat resulting in malfunctioning equipment not working efficiently and find more and more heat equations there may be a fire. Machine heat Is like the heat of a person's body, when the body temperature increases beyond normal we will get sick and unable to do things at their full potential Therefore, we consider the maintenance of the machine. And can solve problems with high temperature machines with Chiller to help.
Chiller It is a cooling machine, a water chiller, both large and small. Its main function is to produce coolness, reduce the temperature and dissipate heat by using water as the main factor in exchanging and transferring coolness from the chiller. Currently, chillers are used in industrial plants to cool machines, maintain machines to last longer and help maintain the efficiency of the machines.
Chiller is a refrigeration. Water cooler There are both large and small. It is the main function of cold production reduce the temperature and cooling.
Use water as the main medium for exchanging and dissipating heat from the cooling machine.
Chillers are currently used in industrial plants to cool down machines, maintain them for a long time, and help maintain their efficiency.
For example, closed-loop wells, hydraulic injection molding machines, and CNC machines.
For example : Closed system pond, Hydraulic injection molding machine, CNC Engraving Cutting CO2, CNC Laser Engraving UV, CNC Router Milling, CNC Fiber Laser and other.

Chiller Water CoolingVSCooling Tower
Cooling Tower Used in industry Hydraulic Injection Molding Machine Mostly because cooling towers have quite a few disadvantages. The machine is large, it is an open system that is difficult to maintain, dust and sediment are easily able to enter the machine, which negatively affects the operation and shortens the lifespan.
Therefore, the manufacturing industry tends to turn to use Chiller (Chiller Water Cooling) The machine is small, compact, saves working space, is a closed system, prevents dust and sediment well, and has a long service life.

❌ Open system
❌ Open system operation
✅ Closed system
✅ Closed-system operation
❌ Since the machine is an open system Causing dust and other sediments to enter the machine easily. It will clog, rust and affect the usability of the machine.
❌ Since it works as an open system, dust, debris, etc. are very likely to enter the machine, causing blockage, rust, and definitely affecting the machine's operation.
✅ The machine is a closed system. Prevents dust and other debris from entering the machine. Changing the water is easy.
✅ With a closed system operation, it prevents dust and sediment from entering the machine. Changing water is also convenient.
❌ Cleaning made difficult.
❌ Cleaning the machine is difficult.
✅ Cleaning made easy.
✅ Cleaning the machine is easy.
❌ The machine is large, takes up quite a lot of work space.
❌ The machine is large and requires a lot of working space.
✅ The machine is small, save working space.
✅ The machine is small in size, saving a lot of working space.
❌ Short term

Preliminary fixes
E01
Temperature sensor cannot measure.
–
E02
Water temperature is too high
Leave it open for a while and observe that the water temperature will gradually decrease (the water temperature must be lower than 30 from the factory).
E03
Compressor pressure failure
Remove the water pipe, only the water inlet (Inlet), find something else to hold the water, then turn on the machine.
E04
Electrical phase sequence error
Switch the power to the L, N device.
E05
Water flow is problematic
Check the water pipe for folds, the water flow should be smooth, nothing should block the water path.
E06
Water level too high – too low
Check the water in the tank to see if it is too low or too high (see the water gauge on the back of the machine).
E07
Over load compressor
The compressor is working too hard, turn off the power, turn the compressor blades by hand to see if they rotate smoothly, the electric current is flowing too much.
E08
Low water temperature warning
Water temperature is too low, chances of freezing are high, need to increase water temperature (add hot water).
E09
Room temperature sensor failed
–
E10
Water temperature is too high

Press the button (or the gear-shaped symbol)
Press the Up or Down (▲ ▼) buttons to set the temperature.
Press the button Once again, to save
Working characteristics For example, the user sets the temperature at 25 degrees, the compressor will work until the water temperature drops to 23 degrees (according to the factory value, as seen in the current temperature display). After that, the compressor will stop working. When the temperature is more than 27 degrees (according to the factory value), the compressor will start working again.
If you observe, you will see that the temperature has a difference of +/- 2 degrees, which is the factory set value. If the user needs to set the value +/- higher, they can edit the value according to the parameter table.
5. Parameter settings (change factory values)
Condition: User must have knowledge about the machine, otherwise changing the parameters may cause the machine to have problems.
Parameter setting procedure
