Agitated immersion tanks are used for passivation as they are designed for precision cleaning using water based detergents and citric acid or nitric acid.
Multi-Stage Passivation System
Ultrasonic Wash – Rinse – Acid Passivate- Rinse – Dry System
Agitating parts washers and systems use a simple yet rugged designed pneumatically powered reciprocating platform to agitate your parts in the water or solvent based detergent. This action coupled with options like ultrasonics, exclusive high flow filtration and turbulation, and oil removal systems ensure all oil and particulate are removed from not only the outside of your parts but also the internal cavities/passages that other types of parts washing systems can’t properly clean.
Once cleaned and rinsed, the parts are immersed in citric acid or nitric acid to perform the passivation process of removing free irons from the surface of the parts.
Automated Multi-Stage Ultrasonic Passivation Systems
Wash – Rinse – Passivate- Rinse – Dry System
These immersion tank washers are fully modular allowing for multiple tanks placed side by side allowing for any applications specific configuration: wash, rinse, dry or wash, rinse, rinse, dry or wash, rinse, passivate, rinse dry, etc as shown above.
Common Applications for Passivation Systems
This superior part exterior and part internals flushing action makes our parts washers excellent for:
- Citric acid passivation type 1, 2, 3, 4, & 5 ASTM A967 using CitriSurf®
- Cleaning and passivation of parts with lots of internal passageways like casting and cylinder blocks
- Medical and aerospace parts with critical cleaning requirements
