Standard voltage and frequency for the three phase motor: 440-480 V (Y)/ 254-277 V (△)-60 Hz

The actual cooling efficiency is decided by the oil flow Q and temperature difference △t=1k (inlet oil temperature

and environment temperature).

Oil flow Q [l/min]

The pressure difference caused to the cooler by the oil viscosity would be 32 mm2/s.
