Cloudray CW-5200 6L Water Chiller for CO2 Lasers
The CW-5200 from Cloudray offers a 6L tank and a 5,699 BTU/h cooling capacity, designed for 60W–150W CO2 laser engraving and cutting. It uses a 0.9HP compressor to stabilize temperatures and accommodates deionized water or antifreeze up to 30%. The system supports a 3.43 GPM flow rate and features reinforced handles for easy transport between job sites. Compatible with industrial environments, it maintains precise cooling down to 5°C (41°F) with R-410a refrigerant.
Key benefits include robust thermal management for continuous operations, a compact footprint (about 22.8″ L x 11.5″ W x 18.5″ H), and durable construction that helps protect laser tubes up to 150W. The unit is a practical fit for factories, workshops, and makerspaces needing reliable chiller performance with straightforward maintenance.
OMTech CW-3000 9L Industrial Water Chiller
OMTech’s CW-3000 is a 9L capacity water chiller that delivers 2.6 GPM flow and a 50W/°C cooling capacity. It’s designed to handle 40W CO2 systems, including K40 setups, with energy-efficient operation that radiates heat away rather than relying solely on refrigeration. The enclosed tank minimizes evaporation, and a clear window helps operators monitor water levels between refills. Brass inlet/outlet ports provide corrosion resistance and better leak resistance in busy shop environments.
Practical considerations include a balance of moderate power and higher tank capacity, making it a solid option for shops with multiple laser tasks. The design supports stable temperature control during longer engraving sessions and reduces the need for frequent top-offs, contributing to smoother production schedules.
S&A CW-5200DH 7L Industrial Water Chiller
The S&A CW-5200DH is a 7L (about 1.85 gallon) water chiller rated for up to 150W laser systems, delivering 3.43 GPM flow and 5,699 BTU/h cooling with a 0.9HP compressor. It uses R410a refrigerant and features a closed-design water tank to minimize evaporation and extend operation time between fillings. Brass ports resist corrosion, and the unit includes dual fans for efficient heat removal. A built-in water level scale keeps operators informed without opening the tank.
This model emphasizes reliability in demanding environments with a focus on long-term service between refills. Its combination of robust cooling, solid plumbing components, and user-friendly indicators makes it a strong choice for shops that run multiple shifts or maintain a small fleet of laser machines.
OMTech CW-5200 6L Industrial Water Chiller
OMTech’s CW-5200 6L unit provides 2.6 GPM flow and a 0.9HP compressor to cool laser systems up to 150W with a cooling capacity near 5,186 BTU/h. The 6L tank is enclosed to cut evaporation, and a clear observation window helps track fill levels. Brass inlet and outlet ports minimize corrosion and leaks, while dual cooling fans enhance heat dissipation. The unit uses R-410a refrigerant for reliable performance in workshop settings.
Ideal for mid-size laser configurations, this chiller balances compact size with durable metal construction. It supports steady operation during engraving or cutting tasks and is suitable for users upgrading from smaller cold plungers or seeking a dedicated cooling solution for a single high-demand CO2 laser machine.
Cloudray CW-5200 6L Industrial CO2 Laser Water Chiller
This Cloudray CW-5200 6L chiller is designed for CO2 laser engraving and cutting up to 150W. It includes a 6L tank and a robust fluid management design with a clear fill window for quick checks. The unit features compressor time-delay protection, overcurrent protection, water flow alarms, and temperature alarms, providing multi-layer protection for continuous operation in demanding shop environments. The system is well-suited for workshops that require reliable, straightforward cooling with minimal maintenance.
Key attributes include a compact form factor, solid build quality, and safety features that help maintain laser performance during long production runs. It provides a dependable cooling baseline for a range of CO2 laser tasks while preserving ease of use for technicians and operators.
Buying Guide: Key Considerations For Choosing A Laser Cutter Water Chiller
- Cooling capacity and flow rate: Match BTU/h and gallons per minute to your laser power (60W–150W typical). Higher BTU/h and flow deliver faster heat removal, supporting longer continuous runs.
- Tank size and evaporation control: Larger tanks reduce refills, while enclosed designs minimize evaporation. Consider the available space in your shop when selecting tank capacity.
- Refrigerant type and energy efficiency: R-410a is common and reliable. Look for units with efficient compressors and fans to lower energy use during operation.
- Tank build and valve quality: Brass ports and corrosion-resistant components improve longevity and reduce leaks in humid environments or when using deionized water.
- Protection features: Temperature alarms, water-flow alarms, and time-delay protections help prevent laser damage and downtime by highlighting issues early.
- Maintenance and accessibility: Easy access to fill levels, simple drain valves, and straightforward cleaning processes extend the usable life of the chiller.
- Portability vs. fixed installation: Wheeled transport or light-duty handles aid movement between workstations, especially in multi-machine setups.
- Compatibility with coolants: Some units specify compatible fluids (deionized water or antifreeze blends). Ensure compatibility with your laser tube and coolant plan.
When selecting a water chiller for a laser cutter, consider current and planned workload, machine wattage, and space constraints. Prioritize units with robust build quality, reliable protection features, and clear user indicators. For facilities with multiple machines, a higher-capacity model with easy maintenance can improve uptime and streamline service intervals.
