Process review
Fluids, properties, operating cases and constraints.
ARO controls sizing, simulation, plate development, tooling, welding, inspection and performance validation across the product lifecycle.
Fluids, properties, operating cases and constraints.
Area, plate pattern, passes and pressure drop.
Pressure vessel, nozzle loads, thermal stress and code.
Plate forming, cleaning, automatic welding and assembly.
Leak, pressure, material and documentation checks.
Simulation supports plate-pattern development, distribution design, velocity control, pressure-drop evaluation and identification of under-utilized regions.

Independent plate-pattern and forming-tool design enables application-specific channel geometry.
Dedicated internal circular welding equipment controls penetration and repeatability.
Specialized equipment welds the circumference of plate pairs into the complete pack.
Plates are ultrasonically cleaned and welded in a dedicated area to manage weld quality.
| Plate-pack pneumatic test | Performed during manufacturing to detect leakage before final assembly. |
|---|---|
| Final hydrostatic test | Complete exchanger tested after assembly according to design requirements. |
| Helium leak testing | Available for vacuum, high-purity and other sensitive services. |
| Oxygen cleaning | Available where components require controlled cleanliness for oxygen service. |
| Thermal performance test | Used to compare sizing-software predictions with measured operation. |
| Burst testing | Development testing used to validate plate-pack strength margins. |
