FAQ

Various industries use industrial water chillers, including manufacturing, pharmaceuticals, plastics, food and beverage, laser cutting, welding, marking and many others.

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.

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.

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.

Deionised water, distilled water or purified water (less impurities)

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.

Safety precautions include ensuring proper ventilation, electrical safety, and regular inspections to prevent leaks or system failures that could pose risks.

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.

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 info@mcwlaser.com.
