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 filtered and 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 11, Specifications. Poor water quality will drastically shorten component life
and void the warranty.
Cutting water supply piping must be sized to meet the flow and pressure requirements listed in
Table 2-7. Only PVC, copper or rubber hoses should be used between the cutting water source
and the machine.
The inlet water must be maintained at a minimum pressure of 35 psi (2.4 bar) at all times. If the
facility water pressure is below, or can fall below 35 psi (2.4 bar), a water pressure booster pump
is required.
NOTE
The machine will not start if inlet cutting water pressure is below 30 psi (2 bar).
Drain
Cutting water released through the safety dump valve when the emergency stop button is initiated
is discharged from the drain port. The discharge is considered wastewater and must be piped to
an appropriate location, i.e. a sewer line. The volume of water released will be minimal and does
not require high pressure plumbing; however, piping must comply with local, regional and
national codes.
Plant Air
The facility compressed air connection should provide clean, dry air regulated to 85 psi (5.9 bar).
Air usage is minimal, normally less than 1 scf/m.
The following table provides specifications for each ISO air quality classification. KMT
recommends adherence to Quality Class 4.
