Cloudray CW-3000 Water Chiller for CO2 Lasers
Designed for 40W–50W CO2 laser systems, the CW-3000 delivers approximately 50W per degree Celsius cooling capacity. It includes a 9L water tank and a built-in digital controller for precise temperature management, plus safety alarms and an anti-clog heat exchanger to protect the laser tube during extended runs.
Cloudray CW-5200 6L Chiller for CO2 Lasers
The CW-5200 provides substantial cooling for higher-wattage laser systems, capable of handling 60–150W CO2 lasers with a 6L tank and a 3.43 GPM flow. The unit maintains stable temperatures as low as 5°C (41°F) using R-410a refrigerant and is designed for easy transport and robust workshop use.
S&A CW-5200DH 7L Industrial Water Chiller
Engineered for 60W–150W CO2 laser engraving and cutting, this unit uses R410a refrigerant and delivers up to 5699 BTU/h cooling. It features a 7L tank, a 3.4 GPM flow, brass ports, dual cooling fans, and a viewing window to monitor water levels—combining durability with practical day-to-day use.
VEVOR CW-3000(PRO) Industrial Water Cooler
Compared to standard CW-3000 units, the PRO version uses a 18 L/min flow with a 12 L tank and a durable air-cooled design. It supports cooling for 40–80W CO2 laser tubes and is built with a high-efficiency fan and corrosion-resistant brass connections to enhance longevity and performance in busy shops.
OMTech CO2 Laser Coolant and Water Chiller
OMTech’s coolant solution emphasizes compatibility with laser tubes by preventing freezing and overheating. The 1-gallon ethanol-free antifreeze and corrosion inhibitors maintain safe operation, with a focus on protecting laser outputs during extreme conditions. Use caution with coolant mixing and ensure compatibility with your system’s materials.
OMTECH 9L Industrial Water Chiller CW-3000
The CW-3000 model by OMTech radiates heat efficiently with a 9L tank and 2.6 GPM flow. It supports 50W of heat per degree Celsius, enabling stable cooling for typical 40W K40 laser setups and related equipment. The design emphasizes reliable brass fittings and visibility for easy maintenance.
Buying Guide: Key Purchase Considerations
- Laser wattage compatibility: Choose a chiller rated to handle your laser’s wattage (60–150W systems need robust cooling and higher BTU ratings).
- Cooling capacity and flow: Higher flow rates (GPM) and BTU/h indicate faster heat dissipation, which matters during long engraving sessions.
- Tank size and evaporation: Larger tanks reduce refills; consider a viewing window to gauge water levels quickly.
- Temperature control accuracy: Precise regulation (±0.1°C to ±0.5°C) minimizes thermal stress on laser tubes.
- System compatibility: Look for brass ports and corrosion resistance; ensure fluid compatibility with deionized water or approved antifreeze mixtures.
- Safety features: Alarms for over-temperature and low water flow prevent damage and downtime.
- Portability and fit: Dimensions and weight affect placement in your workspace; consider wheeled carts if frequently moved.
- Maintenance requirements: Filter access, anti-clog designs, and easy drainage help sustain performance.
- Noise and energy use: Air-cooled designs can be quieter and less energy-intensive than some compressor-based models.
- Brand and support: Reputable brands often provide clearer documentation, spares availability, and service support.
When evaluating options, align cooling capacity with your laser power, account for the number of hours you operate, and consider ongoing costs such as replacement filters and fluids. A robust chiller reduces downtime, maintains output stability, and protects laser tubes from thermal damage.
