Why do the fiber laser chiller need two independent cooling

Below is the introduction of fiber laser from our customer:
4,000W 970nm laser head, with driver (includes power supply and controller plus software). Laser head is optically terminated with a QBH-compatible fiber optic module and supplied with a 100μm fiber with QBH termination.
Therefore, the chiller is required to provide two independent cooling.
Generally speaking, cooling 500W fiber laser ,we recommend chiller CW-6100AT with dual pump& dual temp function; Cooling 750W-1000W fiber laser, chiller CW-6200AT is satisfied with the demand which also has dual pump & dual temp function.
