Chiller Troubleshooting
Precise Temperature Control for Laser Systems and Industrial Applications Since 2002

In this video, TEYU S&A guides you in diagnosing the ultrahigh water temperature alarm on the laser chiller CWFL-2000. First, check if the fan is running and blowing hot air when the chiller is in normal cooling mode. If not, it could be due to a lack of voltage or a stuck fan. Next, investigate the cooling system if the fan blows out cold air by removing the side panel. Check for abnormal vibration in the compressor, indicating failure or a blockage. Test the dryer filter and capillary for warmth, as cold temperatures may indicate a blockage or refrigerant leakage. Feel the temperature of the copper pipe at the evaporator inlet, which should be icy cold; if warm, inspect the solenoid valve. Observe temperature changes after removing the solenoid valve: a cold copper pipe indicates a faulty temp controller, while no change suggests a faulty solenoid valve core. Frost on the copper pipe indicates a blockage, while oily leaks suggest refrigerant leakage. Seek a professional welder or return the fiber laser chiller CWFL-2000 to the factory for repairs.
TEYU Chiller was founded in 2002 with many years of chiller manufacturing experience, and now is recognized as a cooling technology pioneer and reliable partner in laser industry. TEYU Chiller delivers what it promises - providing high performance, highly reliable and energy efficient industrial water chillers with superior quality.
Our recirculating water chillers are ideal for a wide variety of industrial applications. And for laser application in particular, we develop a complete line of laser chillers, ranging from stand-alone unit to rack mount unit, from low power to high power series, from ±1℃ to ±0.1℃ stability technique applied.
The water chillers are widely used to cool fiber laser, CO2 laser, UV laser, ultrafast laser, etc. Other industrial applications include CNC spindle, machine tool, UV printer, vacuum pump, MRI equipment, induction furnace, rotary evaporator, medical diagnostic equipment and other equipment that requires precise cooling.
