Condition: new, Year of construction: 2026, CW-3000 Water Chiller for CO₂ Laser Engravers and Cutting Plotters The CW-3000 is a compact water cooling system designed for CO₂ laser engravers and cutting plotters, suitable for laser tubes with a power rating of approximately up to 80 W. It maintains a stable coolant temperature, protecting the laser source against overheating and power fluctuations. It is a simple and effective solution for achieving consistent cutting and engraving quality while reducing the risk of production downtime. The unit uses an efficient fan and heat exchanger system, making it lightweight, space-saving, and easy to integrate into existing cooling installations. Why CW-3000 improves process safety and quality Protection of laser components – stable cooling reduces temperature fluctuations inside the laser tube and minimizes the risk of thermal overload of the entire system (tube, power supply, connectors, and water circulation circuit). This ensures safer and more predictable operation. Extended CO₂ laser tube lifespan – maintaining the recommended operating temperature range helps preserve output parameters for longer and delays the need for tube replacement. Improved cutting and engraving quality – stable temperature means stable laser beam power, helping achieve consistent results, cleaner edges, and fewer corrections. Continuous production operation – reduced risk of thermal alarms and cooling-related interruptions ensures a more predictable workflow. Cost-effective operation – simple construction, compact dimensions, and low power consumption make daily operation easier and help reduce maintenance costs. Applications The CW-3000 cooling system is designed for: CO₂ laser plotters and engravers used in light and medium-duty applications where repeatable quality and low operating costs are important. Advertising workshops, prototyping studios, and small production facilities where reliable cooling is required with limited installation space. Dsdpfx Akoy Sg H Iomoku Recommended operating practices Use clean coolant and regularly check the fluid level; ensure the circulation system remains unobstructed and all connections are leak-free. Provide sufficient airflow around the heat exchanger and cooling fan. Periodically clean the filter and reservoir and check the coolant flow to maintain efficiency and protect system components.
