When selecting a water chiller for your 80W CO2 laser engraver, consider these factors:
(1)Cooling Capacity: Ensure the water chiller can handle the heat load of your laser engraver, typically measured in watts. For an 80W CO2 laser, a water chiller with a cooling capacity of at least 700W (0.7kW) is recommended.
(2)Temperature Stability: Choose a water chiller that maintains stable temperature control, ideally within ±0.3°C to ±0.5°C.
(3)Flow Rate: Ensure the water chiller provides an adequate flow rate, usually specified by the laser manufacturer. For an 80W CO2 laser, a flow rate of around 2-4 liters per minute (L/min) is typical.
(4)Portability: It could be a big problem if there is not enough space, so consider the water chiller's size, weight, and ease of mobility before purchasing.
