- Modular construction with integrated pump, tank, and heat exchanger
- Suitable for demanding applications with flow rates up to 80 l/min and cooling capacity up to 9 kW
Hydac Cooling Systems FLKS-170S, 340S, 340SL
The FLKS is a compact, complete fluid-air cooling system, which is used primarily for cooling and lubrication circuits.
The cooling system is modular in structure and is comprised of one axial or radial fan, one tank with circulating pump and one heat exchanger.
Function:
The pump conveys the cold operating medium out of the tank via the component to be cooled and picks up the heat there. The heated operating medium flows through the heat exchanger where the fan provides the necessary air flow for cooling the medium back down.
Standard version with water-glycol (W) or mineral oil (M)
