Sistemas de resfriamento FLKS -3S/1.0/W… FLKS – 3L/1.0/W…

APPLICATIONS

Cooling circuits:

  • Cooling of AC main drives
  • Cooling of motor spindles on machining centres
  • Cooling of transmission and braking systems
  • Cooling of servo and linear motors

CONSTRUCTION

The HYDAC FLKS fluid air cooling system consists of an axial fan, a tank, a submersible pump and a heat exchanger.
The submersible pump built into the plastic tank pumps the coolant through the heat exchanger.
The axial fan provides the necessary cooling air through the heat exchanger.
