COOLING IN
Water-cooled system: Low-pressure supply water or water from a chiller that goes to a heat exchanger
Air-cooled system: Hydraulic fluid that is returning from an external air cooler
cooling mode
The pump runs with the intensifier disabled. Hydraulic fluid circulates through the pump at minimum pressure,
the cutting-water solenoid is open, and the boost pump is on.
COOLING OUT
Water-cooled system: Low-pressure water from the heat exchanger that goes to a drain or returns to a chiller
Air-cooled system: Hydraulic fluid that is sent to an external air cooler
cooling water
Low-pressure water that circulates through the heat exchanger in water-cooled systems to cool the hydraulic
fluid, refer to
