Industrial Water Chiller for Laser Engraving

The SIHAO CW-5000 is a 6L industrial water chiller designed to cool CO2 glass laser tubes rated up to 60W or 80W in engraving and cutting machines. It operates on 110V at 60Hz with a current draw of 4.5 to 7A and includes a compressor rated at 0.75KW. The unit provides a refrigerating capacity of 5186Btu/h and offers temperature precision of ±0.3.

Sustained Load Behaviour with Compressor Cooling

Unlike passive thermolysis coolers, this model uses active compressor refrigeration rated at 1.52KW to maintain stable coolant temperatures during continuous laser operation. The system delivers a maximum flow of 12L/min and a maximum pumping lift of 12m to ensure consistent circulation. Multiple alarm functions monitor flow, high and low temperature, compressor delay, and overcurrent conditions, cutting power if current exceeds secure thresholds.

Interface and Installation Practical Limits

The chiller measures 64cm by 38cm by 52cm and weighs 23kg, requiring adequate bench or floor space near the laser machine. It connects via a standard power cable to a 110V 60Hz supply and uses forced water pump circulation with included sealing washers for plumbing connections. The 6L tank capacity and 12L/min flow rate set the practical limits for loop volume and heat removal in a closed-loop cooling circuit.

Questions about this item

How loud is the CW-5000 when it runs continuously all day?

The compressor is rated at 0.75 kW and draws 4.5–7 A at 110 V, so expect a steady hum comparable to a small refrigerator.

What must I already own to connect the CW-5000 to my laser engraver?

You need a 110 V / 60 Hz supply, two hose barbs for 12 mm tubing, and a laser tube rated up to 60 W or 80 W CO₂ glass.

Will the CW-5000 work with my older 50 W CO₂ laser tube?

Yes — the chiller is designed for one CO₂ glass tube under 60 W / 80 W, so a 50 W tube falls within its 1.52 kW refrigerating capacity.
