Cooling Water (Oil-to-Water Models)
Inlet cooling water flows through the oil-to-water heat exchanger in the hydraulic system to
control heat buildup in the hydraulic oil. The cooling water is then discharged through the
cooling water out port to either the drain or routed to a customer supplied water chiller.
Cooling water supply piping must be sized to meet the flow and pressure requirements of the
equipment. If municipal or well water is used for cooling, ensure the supply flow and pressure
meet the requirements in Section 10, Specifications.
If a facility-wide chilled water system is used for cooling, ensure there is a minimum of 35 psi
(2.4 bar) pressure differential between the facility supply and discharge plumbing. Installation of
an in-line pressure boosting pump may be necessary to provide adequate cooling flow. Dedicated
chilled water systems should be sized according to pump horsepower as illustrated in Table 2-4,
Chilled Water Systems.

Note: Coolant flow to the heat exchanger is regulated
by the temperature of the contents in the
hydraulic reservoir and will be shut off at times.
Cutting Water
Inlet cutting water is routed to the intensifier where it is pressurized and delivered to the cutting
head. The cutting water supply must meet the minimum water quality standards outlined in
Section 10, Specifications. Poor water quality will drastically shorten component life and void
the warranty.
