CNC spindle cooler CW-3000 is a perfect solution to enhance the performance of 1500W CNC cutting machine spindle. Being affordable and easy to operate, this passive cooling small recirculating water chiller can dissipate the heat from the spindle effectively while at the same time consuming less energy than its counterparts. It features a heat dissipation capacity of 50W/℃, which means it can absorb 50W of heat by rising 1°C of water temperature. Although CW 3000 chiller is not equipped with compressor, effective heat exchange can be guaranteed thanks to a high speed fan inside.
