S&A CW3000 TG Industrial Water Chiller (for CO2 Laser)

The S&A CW3000 TG Industrial Water Chiller is a compact recirculating cooling unit designed for CO2 laser engraving and cutting machines using water-cooled glass laser tubes. It circulates cooling water through the laser tube and helps remove heat during operation, supporting more stable laser performance and longer tube life.

The CW3000 is a passive cooling chiller, meaning it uses a radiator and high-speed fan for heat dissipation instead of a refrigeration compressor. It is a practical cooling solution for suitable low to medium power CO2 laser machines where water circulation and heat removal are required.

With a 9L water tank, digital temperature display, flow alarm protection, and compact body design, the CW3000 TG is suitable for laser engraving workshops, small production setups, schools, makerspaces, and businesses using CO2 laser engraving machines.

Passive Cooling for CO2 Laser Tubes

The CW3000 TG is designed to circulate cooling water through the CO2 laser tube and release heat through its internal radiator and fan system. This helps prevent heat buildup during laser operation and supports more consistent laser output.

Since this model is a passive cooling unit, it does not actively refrigerate water below room temperature. Its cooling performance depends on ambient room temperature, ventilation, laser power, and machine usage time.

Suitable for CO2 Laser Engraving Machines

This chiller is suitable for CO2 laser engraving machines using DC glass laser tubes up to 80W. It is commonly used with laser engraving and cutting machines for acrylic, wood, MDF, leather, rubber, paper, and other compatible CO2 laser materials.

For higher-power laser tubes, long continuous cutting jobs, or hot workshop environments, a compressor-based model such as CW5000 or CW5200 may be more suitable.

9L Water Tank and Recirculating Flow

The 9L water tank provides a dedicated cooling water supply for the laser tube. The chiller continuously circulates water through the laser system, helping maintain a more controlled operating condition compared with basic bucket-and-pump setups.

Proper water quality and regular water changes are important for protecting both the chiller and the laser tube.

Digital Display and Alarm Protection

The digital temperature display shows the current water temperature and alarm information. The built-in flow alarm helps protect the laser system by warning the user when water circulation is not normal.

This is an important safety feature because poor water flow can quickly lead to overheating and possible laser tube damage.

Compact and Easy to Use

The CW3000 TG has a compact body size and an integrated top handle, making it easier to place near a laser machine or move when needed. Its simple design makes it suitable for users who need reliable water circulation and passive heat dissipation without complex setup.

Usage Note

Use distilled water, deionised water, or purified water for better long-term protection. Place the chiller in a dry, well-ventilated area and keep the surrounding airflow clear. The CW3000 TG is a passive cooling unit, so it cannot reduce water temperature below the surrounding room temperature.
