Our automated ultrasonic nitric or citric acid passivation equipment clean, rinse, passivate, rinse and dry by moving the fluids from heated storage tanks into a single ultrasonic process tank, rather than moving the parts basket through a series of tanks. Modular heated storage tanks complete the system for re-use of detergents and rinse water. This system configuration eliminates operator interaction, variability and eliminates exposure to chemicals. This unique system design can save up to 50% of passivation equipment cost vs. traditional mulit-tank setups with overhead index automation/robotics.
