The customer used to adopt cooling pump to cool spindle, however, they found the cooling performance is poor especially in summer.
Cooling a single 1.5KW spindle of 2400R/min speed rate, S&A thermolysis type chiller CW-3000 is satisfied with cooling demand. Besides, as the chiller will be used in Malaysia and the voltage is not stable sometimes. As a result, we suggest using voltage regulator to protect the chiller.
