Heat Exchanger (500 psi, 4-Pass, 250 Degree)

Used to control hydraulic oil temperature in Flow waterjet pump systems. Its multi-pass design increases heat transfer efficiency by routing fluid through multiple passes inside the exchanger, helping stabilize operating temperature during long cutting cycles and reducing thermal stress on hydraulic components. This heat exchanger is used when cooling performance has dropped, the existing exchanger is leaking, or oil temperature is rising beyond normal operating range.

Service note: Before replacing a heat exchanger, inspect cooling-water supply, oil condition, hydraulic filters, and the surrounding plumbing for restriction or contamination. A clean cooling loop and proper flow rate are critical for maintaining stable hydraulic oil temperature and protecting the pump from heat-related wear.
