Custom Solution | Helium Hard Vacuum System for Refrigeration Assemblies

SKU:

X-1P30021

Aerospace equipment company required a custom leak test system for multiple models of refrigeration assemblies. Test requirements include a nitrogen proof and gross leak test prior to the helium test. We engineered a custom turnkey leak test system with custom programmed controller software to automate a leak test process that required custom test recipes for multiple leak test methods, parts, and leak rates.
