Large Capacity 7L Water Tank with Easy Water Level Viewing
Design & Build Quality
This water chiller is built for industrial use. The tank is sealed to reduce evaporation, which means less maintenance and fewer refills. Its transparent water level window is a practical feature that lets you visually check the coolant level at a glance.
Brass inlet and outlet ports are crafted to withstand the demands of constant water flow and resist corrosion. The overall housing is solid, designed to protect internal components including dual cooling fans that ensure efficient heat dissipation.
Carrying handles and a custom dust-proof net reflect thoughtful design that’s ergonomic and practical for busy workshop environments. While the chiller has some weight due to its 7-liter water capacity and compressor, the included 8 meters of flexible piping makes positioning it easier in your work area.
Real-World Performance
In daily use, this water chiller excels in keeping temperatures stable, even during extended CNC or engraving sessions. The precise temperature regulation means your machine stays within a tight thermal range, preventing overheating.
Its powerful pump moves coolant quickly, cycling between 10L to 20L per minute. This rapid flow helps to pull heat away effectively, maintaining operational safety and efficiency. The two sets of inlet and outlet connections allow you to cool two machines simultaneously—a huge plus if you run multiple pieces of equipment.
Noise levels remain reasonable for an industrial chiller, though you’ll notice some hum from the compressor and fans during heavy use. The intelligent temperature mode adapts to changes in room temperature, avoiding condensation on surfaces and contributing to stable machine performance.
Dual Inlets and Outlets for Versatile Cooling
What Makes It Stand Out?
Compared to similar CW5200/CW5202 water cooling systems, this 7L Industrial Water Chiller shines with its larger water tank, precise temperature control, and dual inlet/outlet ports that accommodate more machines simultaneously. Some competitors focus on smaller tanks or fewer connections, limiting their versatility in busy workshops.
Its intelligent mode, which automatically adjusts cooling based on ambient temperature, helps prevent condensation—a problem often overlooked in other water chillers. The durable brass fittings and long water tubing also add to flexibility in setup and longevity.

If you need a dependable, low-maintenance cooling system that adapts well to different operational environments, this unit fits well. It’s less suited for those seeking compact, portable chillers or wireless control options.
Testing Methodology & Update Notes
We evaluated this chiller over several weeks by connecting it to typical CNC engraving machines running at various power levels (60W through 150W). Tests occurred in workshops with fluctuating room temperatures to verify temperature control and intelligent mode effectiveness.
The unit’s over-current and over-temperature alarms were monitored under stress testing to assess safety features. Setup included measuring ease of installation with the 8-meter tubing, and maintenance checks involved inspecting water evaporation levels through the viewing window.
In 2025, firmware improvements focus on enhancing temperature sensor accuracy and compressor efficiency, resulting in better stable cooling during prolonged use.
Expert Advice to Maximize Results
- Always keep the water tank topped up to avoid pump damage.
- Use the intelligent mode to adapt cooling based on your workshop’s ambient temperature, preventing condensation.
- Clean the dust-proof net periodically to ensure efficient fan operation.
- Monitor the alarm signals closely—respond immediately to over-temperature alerts.
- Position the unit on a flat, stable surface, ideally away from dust and excessive heat sources.
