Product description

Description
These bypass cooling units are used, among other things, when high pressure peaks are to be expected in the return lines of the hydraulic system or the return flow rate is subject to large fluctuations. The units work according to the »recycling principle«. Oil is taken from the tank, cooled and returned to the circuit. The compact combination of electric motor, screw pump, axial fan (pushing air direction) and heat exchanger ensures efficient and cost-effective operation.
