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. For refrigerant quantity, you can c...

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.

If your TEYU S&A fiber laser chiller CWFL-2000 triggers an ultrahigh room temperature alarm (E1), follow these steps to resolve the issue. Press the "▶" button on the temperature controller and check the ambient temperature ("t1"). If it exceeds 40℃, consider changing the water chiller's working environment to the optimal 20-30℃. For normal ambient temperature, ensure proper laser chiller placement with good ventilation. Inspect and clean the dust filter and condenser, using an air gun or water if needed. Maintain air pressure below 3.5 Pa while cleaning the condenser and keep a safe distance from the aluminum fins. After cleaning, check the ambient temp sensor for abnormalities. Perform constant temperature testing by placing the sensor in water at around 30℃ and compare the measured temperature with the actual value. If there's an error, it indicates a faulty sensor. If the alarm persists, contact our customer service for assistance.

The concept of “wastage ” has always been a vexing issue in traditional manufacturing, affecting product costs and carbon reduction efforts. Daily use, normal wear, and tear, oxidation from air exposure, and acid corrosion from rainwater can easily result in a contaminant layer on valuable production equipment and finished surfaces, affecting precision and ultimately impacting their normal usage and lifespan. Laser cleaning, as a new technology replacing traditional cleaning methods, primarily utilizes laser ablation to heat pollutants with laser energy, causing them to instantly evaporate or sublime. As a green cleaning method, it possesses advantages unmatched by traditional approaches. With 21 years of R&D and production of laser chillers, TEYU S&A can provide professional and reliable temperature control for laser cleaning machines.
