Recirculation Loop
Water Cooled Hydraulic Oil Coolers
BASiS:
n
40°F Entering temperature difference (Maintain reservoir 40°F
above the incoming water temperature)
n
Heat removal 30% of input horsepower
n
Hydraulic system flow (GPM) x 3 = Gallons; reservoir size
n
1 GPM cooler flow per HP heat to be removed
n
Turn-over reservoir 3-4 times per hour
