Cooling loop
Compressing hydraulic fluid generates substantial heat that can cause damage to equipment and
decrease the life of the fluid. Fluid that is too hot is thin, which accelerates wear on the parts,
increases the formation of sludge, degrades the fluid, and decreases its lubrication and protective
qualities. Increased temperature can mean that there is a problem with the cooling system.
The cooling loop keeps the hydraulic fluid at its optimum temperature.
Cooling loop for a water-cooled system (internal heat exchanger)
When the primary motor is operating, cooling water goes through the heat exchanger, transferring
heat away from the hydraulic fluid to the cooling water.

Utility panel: C
OOLING IN
Low-pressure supply water or water
from a chiller goes to the heat exchanger.

Utility panel: C
OOLING OUT
Water from the heat exchanger goes to a
chiller or a drain.

Hydraulic fluid tank
Hydraulic fluid goes from the tank to the
gear pump (not shown). From the gear
pump, the hydraulic fluid goes to the
heat exchanger.
5
Hydraulic filter
The gear pump moves hydraulic fluid
from the heat exchanger to the filter and
then into the tank.
