S&A Water Chiller FAQs
What types of industries use industrial water chillers?
Various industries use industrial water chillers, including manufacturing, pharmaceuticals, plastics, food and beverage, laser cutting, welding, marking and many others.
How does an industrial water chiller work?
Industrial water chillers work by circulating chilled water through a closed-loop system. A compressor or refrigeration cycle removes heat from the water, and then the cooled water is pumped through the process or equipment to dissipate heat.
The using condition of water chiller
If you would like to use our chillers, please make sure you can meet the following conditions.
Our water chiller is used for cooling water. If it is other liquids, please make sure there is no corrosion for the water chiller.
When using our water chiller, the water inlet of the water chiller needs to connect with the water outlet of your equipment, and the equipment water inlet connects with the water outlet of our water chiller.
It is required to meet
1). The water flow is uniform
2). There is no impurity in the circulating water.
The range of water temperature that can be cooled
Most of our chillers are used in industry, such as cutting machine and marking machines. The temperature range of the water that can be cooled is 5-40 degrees Celsius.
What can be used as cooling water?
Deionised water, distilled water or purified water (less impurities)
What kind of antifreeze is used?
1). Use ethanol for short-term antifreeze:
If there is a power failure and the cooling water cannot be emptied, temporary short-term antifreeze is required, and ethanol (alcohol) can be added to the deionized or purified water, and the added amount cannot exceed 40% of the volume of the water tank, because ethanol is very corrosive, and it is very corrosive to grease, Paint and rubber parts will corrode, and they are also corrosive to metals, so they cannot be used for a long time. It must be emptied within a week and the cooling pipeline must be cleaned with pure water or deionized water. If there are still antifreeze requirements, special antifreeze must be selected.
2). Use special antifreeze of professional brand:
It is recommended to choose CLARIANT (Clariant) brand, there are two types of antifreeze suitable for laser systems:
(1).Antifrogen-N glycol-water type (industrial products, toxic to human body)
(2). Antifrogen-L propylene glycol-water type (food grade, harmless to human body)
Use Clariant's Antifrogen N antifreeze, the minimum addition ratio is 3:7 [30% antifreeze, 70% water] After adding antifreeze, it can resist -12~-15℃ without freezing. It is generally recommended to add in a ratio of 1:1, which can reach -25 °C without freezing. It should be noted that after adding antifreeze, it can only ensure that the water does not freeze within -25 °C, but it does not mean that the water cooler can work normally at very cold temperatures. The normal working temperature of our water cooler should be above 5℃. The cold start temperature should be above 10 ℃.
Cleaning and Antifreeze
1. To ensure good heat dissipation, please open the lid to clean the dirt after the cooler is used in the long term.
2. Ethanol can be used as a short-term antifreeze, but it is corrosive and needs to be emptied within a week.
Users in cold areas should use noncorrosive special antifreeze.
What safety precautions should be taken when using an industrial water chiller?
Safety precautions include ensuring proper ventilation, electrical safety, and regular inspections to prevent leaks or system failures that could pose risks.
Why is my water chiller not cooling effectively?
Check if the water temperature settings are correct.
Ensure there is enough water in the reservoir.
Clean the condenser coils and filters, as dirt can impede cooling efficiency.
Verify that the compressor and fans are working properly.
Can I use my chiller for both heating and cooling purposes?
Yes,Some of our models of water coolers have this feature. If you would like to add this feature to your existing water chiller, please contact us to learn more at email@example.com.

FWM Laser Welding Machine FAQs
What is the principle of laser welding machine?
Laser welding is a process that uses laser energy to heat metal materials, melting them during the heating process and forming welds, thereby achieving the purpose of welding. Lasers transmit energy through undulating electromagnetic waves, which can be guided to the welding point through optical fibers. When the laser beam irradiates the surface of the workpiece, it will be absorbed and converted into heat energy, causing the workpiece to locally heat up until it melts or reaches the temperature required for welding. As the laser beam moves, the molten pool will also move with it, leaving a complete weld on its path. The welding speed is fast, the weld is small, beautiful and the welding is strong.
What are the classifications of laser welding?
1. Handheld laser welding machine
2. Automatic laser welding machine
