To ensure optimal performance and extend the service life of TEYU S&A fiber laser chillers, regular dust cleaning is highly recommended. Dust buildup on critical components like the air filter and condenser can significantly reduce cooling efficiency, lead to overheating issues, and increase power consumption. Routine maintenance helps maintain consistent temperature control and supports long-term equipment reliability.
For safe and effective cleaning, always turn off the chiller before starting. Remove the filter screen and gently blow off accumulated dust using compressed air, paying close attention to the condenser surface. Once cleaning is complete, securely reinstall all components before powering the unit back on. By incorporating this simple yet important maintenance step into your routine, you can safeguard your chiller's performance and minimize costly downtime.

Water flow is directly tied to the proper functioning of industrial chillers and the temperature control efficiency of the equipment being cooled. TEYU S&A CW-5000 and CW-5200 series feature intuitive flow monitoring, allowing users to keep track of the cooling water flow at any time. This enables better water temperature adjustment as needed, helps prevent insufficient cooling, and prevents equipment damage or shutdown due to overheating.To prevent flow anomalies from affecting the cooled equipment, TEYU S&A industrial chillers CW-5000 and CW-5200 series also come with a flow alarm value setting function. When the flow falls below or exceeds the set threshold, the industrial chiller will sound a flow alarm. Users can set the flow alarm value according to actual needs, avoiding frequent false alarms or missed alarms. TEYU S&A industrial chillers CW-5000 and CW-5200 make flow management easy and ensure the efficient and stable operation of industrial equipment.

The scorching summer heat is upon us! Keep your industrial chiller cool and ensure stable cooling with expert tips from TEYU S&A Chiller Manufacturer. Optimize operating conditions by properly placing the air outlet (1.5m from obstacles) and air inlet (1m from obstacles), using a voltage stabilizer (whose power is 1.5 times the industrial chiller's power), and maintaining an ambient temperature between 20°C and 30°C. Regularly remove dust with an air gun, replace cooling water quarterly with distilled or purified water, and clean or replace filter cartridges and screens to ensure stable water flow. To prevent condensation, raise the set water temperature according to ambient conditions. If you encounter any industrial chiller troubleshooting inquiries, please do not hesitate to contact our customer service team at service@teyuchiller.com.

Do you know how to antifreeze TEYU S&A industrial water chillers in cold winter? Please check the following guidelines: (1)Add antifreeze to the cooling system of the water chiller to lower the freezing point of the circulating water and prevent freezing. Choose the antifreeze ratio based on the lowest local temp. (2)During extremely cold weather when the lowest ambient temp falls ＜-15℃, it's advised to keep the chiller running continuously for 24 hours to prevent the cooling water from freezing. (3)Additionally, adopting insulation measures is helpful, like wrapping the chiller with insulating material. (4)If the chiller machine needs to be shut down during holidays or for maintenance, it's important to shut off the cooling water system, restore the chiller to its factory settings, switch it off and disconnect the power, and open the drain valve to remove the cooling water, and then use an air gun to thoroughly dry out the pipes. (5)Regularly checking the cooling system is im...

This video shows you how to charge the refrigerant for TEYU S&A rack mount chiller RMFL-2000. Remember to work in a well-ventilated area, wear protective gear and avoid smoking. Using a Phillips screwdriver to remove the top metal screws. Locate the refrigerant charging port. Gently turn the charging port outward. Firstly, unscrew the sealing cap of the charging port. Then use the cap to slightly loosen the valve core until the refrigerant is released. Due to the relatively high refrigerant pressure in the copper pipe, do not loosen the valve core completely at a time. After releasing all refrigerant, use a vacuum pump for 60 mins to remove air. Tighten the valve core before vacuuming. Before charging refrigerant, partially unscrew the valve of the refrigerant bottle to purge air from the charging hose. You need to refer to the compressor and model to charge the suitable type and amounts of refrigerant. For more details, you can email to service@teyuchiller.com to consult our af...

Struggling with an E2 alarm on your TEYU S&A fiber laser chiller CWFL-2000? Don't worry, here's a step-by-step troubleshooting guide for you: Use a multimeter to measure the power supply voltage. Then measure the input voltage at points 2 and 4 of the temperature controller with the multimeter. Remove the cover of the electrical box. Use the multimeter to measure points and troubleshoot. Check the cooling fan capacitor's resistance and input voltage. Measure the current and capacitance of the compressor during chiller operation under the cooling mode. The surface temperature of the compressor is high when it starts, you can touch the liquid storage tank to check the vibrations. Measure the current on the white wire and the resistance of the compressor starting capacitance. Finally, inspect the refrigeration system for refrigerant leaks or blockages. In case of refrigerant leakage, there will be obvious oil stains at the leak site, and the evaporator inlet's copper pipe may frost...

In this video, TEYU S&A professional engineer takes the CWFL-12000 laser chiller as an example and guides you step by step carefully to replace the old plate heat exchanger for your TEYU S&A fiber laser chillers.Power off the chiller machine, remove the upper sheet metal and drain all the refrigerant. Cut away the thermal insulation cotton. Use a soldering gun to heat the two connecting copper pipes. Detach the two water pipes, remove the old plate heat exchanger and install the new one. Wrap 10-20 turns of thread seal tape around the water pipe connecting the port of the plate heat exchanger. Place the new heat exchanger in position, make sure the water pipe connections are facing downward, and secure the two copper pipes using a soldering gun. Attach the two water pipes at the bottom and tighten them with two clamps to prevent leaks. Finally, perform a leak test at the soldered joints to ensure a good seal. Then recharge the refrigerant.

Do you know how to troubleshoot the flow alarm in TEYU S&A handheld laser welding chiller? Our engineers specially made a chiller troubleshooting video To help you better solve this chiller error. Let's take a look now~When the flow alarm activates, switch the machine to self-circulation mode, fill the water to the maximum level, disconnect external water pipes, and temporarily connect inlet and outlet ports with pipes. If the alarm persists, the problem might be with external water circuits. After ensuring self-circulation, potential internal water leaks should be examined. Further steps involve checking the water pump for abnormal shaking, noise, or lack of water movement, with instructions on testing pump voltage using a multimeter. If issues persist, troubleshoot the flow switch or sensor, as well as circuit and temperature controller assessments. If you still can't solve the chiller failure, kindly send an email to service@teyuchiller.com to consult TEYU S&A service team.
