What Is An Industrial Chiller? How Does Industrial Chiller Work?

 1. What Is An Industrial Chiller?

An industrial chiller is a cooling device that provides constant temperature, constant current and constant pressure, and lowers the temperature of machinery/industrial spaces by removing heat from the system and transferring it elsewhere.

 

2. Why Do You Need An Industrial Chiller?
No industrial process, machine, or motor is 100% efficient, and heat buildup is the main cause of inefficiency. The heat will accumulate over time causing reduced production times, equipment shutdowns, and even premature equipment failure. An industrial chiller is necessary to incorporate into the industrial process system to avoid these issues.

Premium industrial chillers can optimize the product processing process and quality, increase production efficiency and the lifespan of laser equipment, reducing product losses and machine maintenance costs. Using a professional industrial chiller has numerous benefits. It is a wise choice to ensure stable operation and ultimately improve industrial profits. TEYU S&A Chiller with a 21-year dedication to industrial chillers is confident to provide premium chillers and reliable after-sales service.

 

3. How Does An Industrial Chiller Work?

Refrigeration Principle Of Industrial Chiller For Supporting Equipment: The industrial chiller's refrigeration system cools the water, and the water pump delivers the low-temperature cooling water to the equipment that needs to be cooled. As the cooling water takes away the heat, it heats up and returns to the industrial chiller, where it's cooled again and transported back to the equipment.

Refrigeration Principle Of The Water Chiller Itself: In the industrial chiller's refrigeration system, the refrigerant in the evaporator coil absorbs the heat of the return water and vaporizes it into steam. The compressor continuously extracts the generated steam from the evaporator and compresses it. The compressed high-temperature, high-pressure steam is sent to the condenser and later releases heat (heat extracted by the fan) and condenses into a high-pressure liquid. After being reduced by the throttling device, it enters the evaporator to be vaporized, absorbs the heat of the water, and the whole process circulates constantly.

 

4. Classification of Industrial Chillers
According to the industrial chiller's heat dissipation method, it is mainly divided into air-cooled chillers and water-cooled chillers.

According to the chiller compressors' different classifications, it is mainly divided into piston chillers, scroll chillers, screw chillers and centrifugal chillers.

According to the outlet water temperature of industrial chillers: there are mainly room-temperature chillers, low-temperature chillers and ultra-low-temperature chillers.

According to the cooling capacity of industrial chillers, it's mainly divided into small chillers, medium chillers and large chillers.

 

5. Cooling Applications of Industrial Chillers
Industrial chillers have been used in more than 100 industries such as the laser industry, chemical industry, mechanical processing manufacturing industry, automobiles, electronics, machinery, aviation, plastic manufacturing, metal plating, food production, medical industry, textile printing, and dyeing industry, etc. With the changing demands of the market for temperature control, the cooling applications of industrial chillers in various industries are constantly being broadened and extended.

TEYU S&A Chiller is an industrial chillers manufacturer and supplier with laser as the target application. Since 2002, we have been focusing on the cooling need from fiber lasers, CO2 lasers, ultrafast lasers and UV lasers, etc. Other industrial applications of our recirculating water chillers include CNC spindles, machine tools, UV printers, vacuum pumps, MRI equipment, induction furnaces, rotary evaporators, medical diagnostic equipment and other equipment that requires precise cooling.

6. How to Choose An Industrial Chiller?

Generally, choose the most suitable and cost-effective chiller according to various indicators such as your industry, required cooling capacity, temperature control accuracy requirements, budget, etc. The following points will help you quickly choose high-quality industrial chiller products: (1)A good-quality industrial chiller can cool down to the temperature set by the user in the shortest time because the range of space temperature needs to be lowered is different. (2)A good-quality industrial chiller controls the temperature precisely. (3)A good-quality industrial chiller can alert timely to remind users to handle the problem quickly and protect equipment safety and production stability. (4) An industrial chiller consists of a compressor, evaporator, condenser, expansion valve, water pump, etc. The quality of components also determines the industrial chiller quality. (5)Qualified industrial chiller manufacturer boasts scientific test standards, so their chiller quality is relatively stable.

 

7. Precautions for Using An Industrial Chiller
What should be paid attention to when using industrial chillers? Here are five main points: (1)Recommended environment temperature range from 0℃～45℃, environment humidity of ≤80%RH. (2)Use purified water, distilled water, ionized water, high-purity water and other softened water. But oily liquids, liquids containing solid particles, and liquids corrosive to metals are prohibited. (3)Match the power frequency of the chiller according to the usage situation and ensure that the frequency fluctuation is less than ±1Hz. For long time operation, the power supply is recommended to be stable within ±10V. Keep away from electromagnetic interference sources. Use the voltage regulator and variable-frequency power source when necessary. (4)Use the same type of the same refrigerant brand. The same type of different refrigerant brands can be mixed to use, but the effect may be weakened. Different types of refrigerants should not be mixed. (5)Regular maintenance: keep a ventilated environment; replace the circulating water and remove dust regularly; shut down on holidays, etc.

8. Industrial Chiller Maintenance Tips

Summer Maintenance Tips of Industrial Chiller: (1)Avoid high-temperature alarms: Adjust the chiller's working environment to maintain the optimal ambient temperature between 20℃-30℃. Regularly use an air gun to clean the dust on the industrial chiller's filter gauze and condenser surface. Maintain a distance of more than 1.5m between the chiller's air outlet (fan) and obstacles and a distance of more than 1m between the chiller's air inlet (filter gauze) and obstacles to facilitate heat dissipation. (2)Regularly clean the filter screen as it is where dirt and impurities accumulate the most. If it is too dirty, replace it to ensure stable water flow of the industrial chiller. (3)Regularly replace the circulating water with distilled or purified water in summer if antifreeze was added in winter. This prevents residual antifreeze from affecting equipment operation. Replace the cooling water every 3 months and clean pipeline impurities or residues to keep the water circulation system unobstructed. (4)If the circulating water temperature is lower than the ambient temperature, condensing water may be generated on the surface of the circulating water pipe and cooled components. condensing water can cause a short circuit of the equipment's internal circuit boards or damage the core components of the industrial chiller, which will affect production progress. It is recommended to adjust the set water temperature based on the ambient temperature and laser operating requirements.

Winter Maintenance Tips of Industrial Chiller: (1)Keep the industrial chiller in a ventilated position and remove the dust regularly. (2)Replace circulating water at regular intervals. It's recommended to replace the circulating water once every 3 months. And it's better to select purified water or distilled water to reduce the limescale formation and keep the water circuit smooth. (3)If you don’t use the water chiller in winter, drain the water from the chiller and store the chiller properly. You can cover the machine with a clean plastic bag to prevent dust and moisture from entering the equipment. (4)For areas below 0℃, antifreeze is needed for chiller operation in winter.

9. Common Faults and Solutions of Industrial Chillers

1)Incorrect Chiller Model: The incorrect chiller model has a great impact on industrial processing. You can choose a suitable industrial chiller according to the required cooling capacity, temperature control accuracy, flow rate, budget and other factors. Under the condition of a sufficient budget, try to choose a chiller with a large cooling capacity to cope with the increased cooling demand in hot summer. You can consult the professional team of the industrial chiller manufacturer to avoid incorrect chiller models.

2)Improper Operation: The manufacturer’s instructions for correctly operating industrial chillers are included in the manuals that come with them. Please use it in strict accordance with the instruction manual of the industrial chiller. Correct operation can maintain the effectiveness and service life of the equipment.

3)Maintenance Neglect: Industrial chillers have a lot of maintenance guides, and the common daily maintenance includes maintaining the correct use environment, regular inspection of parts, regular replacement of circulating water, regular dust removal, etc.

4)Other Common Issues

Incorrect thermostat setting: The chiller may not be able to maintain the desired temperature if the thermostat is not set to the proper temperature. Adjust the thermostat setting as necessary to solve this issue.

Chiller Won’t Start: If there is an issue with the electrical supply, such as a loose wire, blown fuse, or tripped circuit breaker, the chiller may not turn on. A broken control panel or thermostat could prevent the chiller from starting. Low refrigerant levels or a leak could prevent the chiller from starting. A failing motor or a seized compressor may prevent the chiller from starting. A broken part or damaged belt may cause the chiller not to start. It’s critical to find and fix the root cause of the problem if the chiller won’t start. And you can call a professional for repair in some circumstances.

Pump Failure: If the pump has failed, the chiller won’t operate correctly since it can’t circulate refrigerant. You need to fix or replace the pump to solve this issue.

Compressor Failure: If the compressor has failed, the chiller won’t be able to cool efficiently since it won’t be able to circulate refrigerant. You need to fix or replace the compressor to solve this issue. 

Condenser Coils Clogged: It's hard for a chiller to effectively dissipate heat when the condenser coils are unclean or clogged and resulting in improper cooling. You need to clean regularly or change the clogged condenser coils to resolve this issue.

High-pressure alarm: (1)Clogging in the filter gauze will lead to insufficient heat radiation. To solve this problem, you can remove the gauze and clean it regularly, keeping good ventilation for air inlet and outlet. (2)Blockage in the condenser may cause a high-pressure failure in the cooling system. It is necessary to do periodic cleaning. (3)Excessive refrigerant: the refrigerant should be released until normal according to the suck and exhaust pressure, balance pressure, and running currently under rated working conditions. (4)Air is mixed in the cooling system and stays in the condenser causing condensation failure and a rise in pressure. The solution is to degas through the air separating valve, air outlet, and the condenser of the chiller.

 

For some other chiller failures, such as high-temperature alarm, water flow alarm, low water level, etc., follow the corresponding methods to solve these problems. If you can't solve it yourself, you can ask the after-sales team of the chiller manufacturer for professional maintenance knowledge.

What Is A Laser Chiller, How to Choose A Laser Chiller?

 What is a laser chiller?

A laser chiller is a self contained device that is used to remove heat from the heat-generating laser source. It can be rack mount or stand-alone type. A suitable temperature range is very helpful in extending the service life of the laser. Therefore, keeping the lasers cool is very important. S&A Teyu offers different kinds of laser chillers applicable to cool various kinds of lasers, including UV laser, fiber laser, CO2 laser, semiconductor laser, ultrafast laser, YAG laser and so on.

What does a laser chiller do?

The laser chiller is mainly used to cool the laser generator of the laser equipment through water circulation and to control the use temperature of the laser generator so that the laser generator can keep working normally for a long time. During the long-term operation of laser equipment, the laser generator will continue to generate high temperatures. If the temperature is too high, it will affect the normal operation of the laser generator. Therefore, a laser chiller is required for temperature control.

Do you need a water chiller for your laser cutting, welding, engraving, marking or printing machine?

Of course need. Here are five reasons: 1)Laser beams generate a substantial amount of heat, and a laser chiller can dissipate the heat and eliminate unnecessary waste heat to result in high-quality laser processing. 2)Laser power and output wavelength are sensitive to temperature changes, and laser chillers can maintain consistency in these elements and provide reliable laser performance to extend the laser's lifespan. 3)Uncontrolled vibration can lead to a decrease in beam quality and laser head vibration, and the laser chiller can maintain the laser beam and shape to reduce waste rates. 4)Drastic temperature changes can put a lot of stress on the laser operating system, but using a laser chiller to cool the system can minimize this stress, reducing defects and system failures. 5)Premium laser chillers can optimize the product processing process and quality, increase production efficiency and the lifespan of laser equipment, reducing product losses and machine maintenance costs.

What temperature should a laser chiller be?

The laser chiller temperature range from 5-35℃, but the ideal temperature range is 20-30℃, which makes the laser chiller reach the best performance. Considering the two factors of laser power and stability, TEYU S&A recommends you set the temperature of 25℃. In hot summer, it can be set at 26-30℃ to avoid condensation.

How to choose a laser chiller?

The most important point is to choose chiller products manufactured by experienced laser chiller manufacturers, which usually means high quality and good services. Second, choose the corresponding chiller according to your laser type, fiber laser, CO2 laser, YAG laser, CNC, UV laser, picosecond/femtosecond laser, etc., all have corresponding laser chillers. Then choose the most suitable and cost-effective laser chiller according to various indicators such as cooling capacity, temperature control accuracy, budget, etc. TEYU S&A chiller manufacturer has 21 years of experience in manufacturing and selling laser chillers. With high-quality and efficient chiller products, preferential prices, good service and 2-year warranty, TEYU S&A is your ideal laser cooling partner.

What are the precautions for using a laser chiller?

Keep environment temperature range from 0℃～45℃, environment humidity of ≤80%RH. Use purified water, distilled water, ionized water, high-purity water and other softened water. Match the power frequency of the laser chiller according to the usage situation and ensure that the frequency fluctuation is less than ±1Hz. Keep the power supply stable within ±10V if it would work for a long time. Keep away from electromagnetic interference sources and use the voltage regulator/variable-frequency power source when necessary. Use the same type of the same refrigerant brand. Keep regular maintenance such as ventilated environment, replacing the circulating water regularly, removing dust regularly,  shut down on holidays, etc.

How to maintain the laser chiller?

In summer: Adjust the chiller's working environment to maintain the optimal ambient temperature between 20℃-30℃. Regularly use an air gun to clean the dust on the laser chiller's filter gauze and condenser surface. Maintain a distance of more than 1.5m between the laser chiller's air outlet (fan) and obstacles and a distance of more than 1m between the chiller's air inlet (filter gauze) and obstacles to facilitate heat dissipation. Regularly clean the filter screen as it is where dirt and impurities accumulate the most. Replace it to ensure stable water flow of the laser chiller if it's too dirty. Regularly replace the circulating water with distilled or purified water in summer if antifreeze was added in winter. Replace the cooling water every 3 months and clean pipeline impurities or residues to keep the water circulation system unobstructed. Adjust the set water temperature based on the ambient temperature and laser operating requirements.

In winter: Keep the laser chiller in a ventilated position and remove the dust regularly. Replace the circulating water once every 3 months and it's better to select purified water or distilled water to reduce the limescale formation and keep the water circuit smooth. Drain the water from the laser chiller and store the chiller properly if you don’t use it in winter. Cover the laser chiller with a clean plastic bag to prevent dust and moisture from entering the equipment. Add antifreeze for the laser chiller when it's below 0℃.

Remarkable Effect of Laser Cleaning Oxide Layers

One class of essential materials used in industries such as aviation, aerospace, automotive, mechanical manufacturing, shipbuilding, and chemical engineering is non-ferrous metal structural materials. However, prolonged usage of these materials leads to the formation of oxide layers, affecting both their appearance and practical use. 

In the past, acid cleaning was primarily employed to remove oxide layers. However, acid cleaning not only damages the materials but also causes environmental pollution. Laser cleaning, on the other hand, offers a perfect solution to these challenges.

But What Exactly Is Laser Cleaning?

Laser cleaning is the process of removing materials from solid (or sometimes liquid) surfaces through the irradiation of laser beams. 

Contaminants on the surface of metal materials mainly include oxide layers (rust layers), paint coatings, and other adherents. These contaminants can be categorized into organic pollutants (such as paint coatings) and inorganic pollutants (such as rust layers).

Oxide layers have excellent absorbability for P-LASER lasers, enabling their vaporization and effective removal. The oxides quickly vaporize under the tiny plasma burst generated by the pulsed laser beam, detach from the target surface, and ultimately result in a clean surface with no oxide residue.

Laser cleaning technology is an advanced technique with broad prospects for research and application in high-precision fields such as aerospace, military equipment, electronics, and electrical engineering. Currently, laser cleaning technology has matured and found applications in several areas. Thanks to its efficiency, environmental friendliness, and excellent cleaning performance, the scope of its applications is gradually expanding.

Laser Cleaning Requires a Suitable Laser Chiller

Laser cleaning is achieved through the use of lasers, and to ensure stable beam output for effective cleaning, the temperature is often a crucial factor. With 21 years of expertise in laser processing cooling, Guangzhou Teyu specializes in providing the CWFL series laser chillers, which are suitable for laser cleaning. TEYU water chillers are equipped with two modes: constant temperature and intelligent temperature control. The two cooling circuits can simultaneously cool the laser and optical components/cleaning heads. With Modbus-485 intelligent communication, monitoring and management become convenient. Guangzhou Teyu also provides professional consulting and after-sales service, with an annual sales volume exceeding 120,000 units. TEYU Chiller is the trustworthy choice!

TEYU Chiller’s Thoughts on the Current Laser Development

 The Never-ending Price War

Before 2010, laser equipment was expensive, from laser marking machines to cutting machines, welding machines, and cleaning machines. The price war has been ongoing. Just when you think you've made a price concession, there's always a competitor offering a lower price. Nowadays, there are laser products with a profit margin of only a few hundred yuan, even for selling marking machines worth tens of thousands of yuan. Some laser products have reached the lowest possible price, but the competition in the industry seems to be increasing rather than decreasing.

Fiber lasers with a power of ten kilowatts were worth 2 million yuan 5 to 6 years ago, but now they have dropped by nearly 90%. The money that used to buy a 10-kilowatt laser cutting machine can now buy a 40-kilowatt machine with money to spare. The industrial laser industry has fallen into the "Moore's Law" trap. Although it seems like technology is advancing rapidly, many companies in this industry are feeling the pressure. The price war looms over many laser companies.

Chinese Laser Products Are Popular Overseas

The intense price war and the three-year pandemic have unexpectedly opened up opportunities for some Chinese companies in foreign trade. Compared to regions like Europe, America, and Japan where laser technology is mature, China's progress in laser products has been relatively slower. However, there are still many developing economies around the world, such as Brazil, Mexico, Turkey, Russia, India, and Southeast Asia, which have decent manufacturing industries but have yet to fully adopt industrial laser equipment and applications. This is where Chinese companies have found opportunities. Compared to the high-priced laser machine tools in Europe and America, Chinese equipment of the same type is cost-effective and highly welcomed in these countries and regions. Correspondingly, the TEYU S&A  laser chillers are also selling well in these countries and regions.

Laser Technology is Facing a Bottleneck

One criterion for assessing whether an industry still has full vitality is to observe if there are continuous new technologies emerging in that industry. The electric vehicle battery industry has been in the spotlight in recent years, not only because of its large market capacity and extensive industrial chain but also due to the constant emergence of new technologies, such as lithium iron phosphate batteries, ternary batteries, and blade batteries, each with different technological routes and battery structures.

Although industrial lasers seem to have new technologies every year, with power levels increasing by 10,000 watts annually and the emergence of 300-watt infrared picosecond lasers, there may be future developments like 1,000-watt picosecond lasers and femtosecond lasers, as well as ultraviolet picosecond and femtosecond lasers. However, when we look at it overall, these advancements only represent incremental steps on the existing technological path, and we haven't seen the emergence of truly new technologies. Since fiber lasers brought revolutionary changes to industrial lasers, there have been few disruptive new technologies.

So, What Will the Next Generation of Lasers Be? 

Currently, companies like TRUMPF dominate the field of disc lasers, and they have even introduced carbon monoxide lasers while maintaining a leading position in extreme ultraviolet lasers used in advanced lithography machines. However, most laser companies are facing significant obstacles and bottlenecks in promoting the emergence and development of new laser technologies, which forces them to focus on the continuous refinement of existing mature technologies and products.

Increasingly Hard to Replace Traditional Methods

The price war has led to a wave of technological iteration in laser equipment, and lasers have penetrated many industries, gradually phasing out older machines used in traditional processes. Nowadays, whether in light industries or heavy industries, many sectors have more or less adopted laser production lines, making it increasingly challenging to achieve further penetration. The capabilities of lasers are currently limited to material cutting, welding, and marking, while processes such as bending, stamping, complex structures, and overlapping assembly in industrial manufacturing have no direct connection to lasers.

Currently, some users are replacing low-power laser equipment with higher-power laser equipment, which is considered an internal iteration within the laser product range. Laser precision processing, which has gained popularity, is often confined to a few industries such as smartphones and display panels. In the recent 2 to 3 years, there has been some equipment demand driven by industries like electric vehicle batteries, agricultural machinery, and heavy industries. However, the scope for new application breakthroughs is still limited.

In terms of successful exploration of new products and applications, handheld laser welding has shown promise. With lower prices, tens of thousands of units are shipped each year, making it far more effective than arc welding. However, it should be noted that laser cleaning, which was popular a few years ago, did not see widespread adoption as dry ice cleaning, which costs only a few thousand yuan, eliminated the cost advantage of lasers. Similarly, plastic laser welding, which received much attention for a while, faced competition from ultrasound welding machines that cost a few thousand yuan but were functioning well despite their noise levels, hindering the development for plastic laser welding machines. While laser equipment can indeed replace many traditional processing methods, for various reasons, the possibility of substitution is becoming increasingly challenging.
