Product description
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.
Low-pressure water Hydraulic fluid
1
Utility panel: COOLING IN
Low-pressure supply water or water from a chiller
goes to the heat exchanger.
2
Internal heat exchanger
3
Utility panel: COOLING OUT
Water from the heat exchanger goes to a chiller or
a drain.
4
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.
