A Finnish manufacturer specializing in precision UV laser marking recently selected the TEYU CWUL-05 water chiller to ensure stable operation of their 3–5 W UV laser system. The project highlights how a compact, high-precision chiller can significantly enhance marking quality, system reliability, and production efficiency.

Customer Requirements
In UV laser marking, even small temperature fluctuations can affect beam stability and marking accuracy. The Finnish customer needed a compact and energy-efficient cooling unit that could maintain precise water temperature control under continuous operation. Their goals were to prevent overheating, maintain consistent laser output, and reduce maintenance downtime.

Cooling Solution: Laser Chiller CWUL-05
To meet these needs, TEYU recommended the CWUL-05 UV laser chiller, a model designed specifically for small-power UV lasers. Its main strengths include:
High temperature precision of ±0.3 °C, ensuring consistent laser output.
Cooling capacity of 380 W, sufficient for UV lasers in the 3–5 W range.
Dual temperature control modes—constant temperature and intelligent automatic control.
Comprehensive protection system with alarms for water flow, temperature, and compressor faults.
Compact, easy-to-move design, ideal for workshops with limited space.

Performance in Finland
After integrating the CWUL-05 chiller into their UV laser marking setup, the Finnish customer reported a clear improvement in process stability. The chiller maintained water temperature steadily around 20 °C during long marking cycles, which:
Prevented overheating and prolonged the lifespan of the UV laser source.
Reduced variations in marking depth and color, improving overall precision.
Minimized downtime through automatic alarms and easy temperature adjustment.
Allowed smooth operation even in Finland's seasonal temperature fluctuations.
