Coolers Olaer Functioning

Operating principleOPERATING PRINCIPLE

Getting the right oil viscosity is an important factor for the oil lifetime, the hydraulic system and all its components. A correct sized cooler will provide ideal running conditions to your hydraulic system.

Air/oil technology coolersAIR/OIL TECHNOLOGY

Air/oil technology

The oil from the return circuit or the branch circuit passes through the radiator tubes. Due to the buffers installed in the pipes, the fluid changes direction 32 times over a surface of 1 cm².

The air is systematically drawn in by the ventilator and crosses over the maximum radiator surface to cool the fluid.

Water/oil plates technology coolersWATER/OIL PLATES TECHNOLOGY

Water/oil plates technology

The PWO heat exchanger operates with a lower input temperature. Consequently, it maintains the oil temperature at a very low level for the majority of applications.

The design of the plates and channels causes a turbulent flow. This effect is the key to faster and more economic cooling.

Plates & gaskets technology

The frame that forms the main structure of the exchanger allows for network connection and support of the plates. Each fluid, once connected, flows from two plates to two plates respectively and in counter-flow in order to optimize heat exchange.

The tightness between the plates is ensured by the seals. This technology enables temperature matching to by degree.

Water/oil shell tubes technology coolersWATER/OIL SHELL TUBES TECHNOLOGY

Shell tubes technology

Used in stationary hydraulic systems.

The fluid to be cooled flows over the outside of the tubes while the refrigerant flows inside the tubes. The pressure of the fluid to be cooled must always be greater than the pressure of the water.
