A cyclic corrosion chamber simulates real-world corrosion environments by automating multi-phase cycles including salt fog exposure, humidity soaks, and forced dry-off phases. These systems test component durability against accelerated corrosion following VDA 233-102, GMW14872, and ASTM G85 standards—critical for automotive and aerospace applications.

Frequently Asked Questions
What is the benefit of CCT over standard salt spray?
CCT better mimics real-world conditions by alternating wet and dry states, which is often more aggressive than constant salt fog.
Can it run standard ASTM B117 salt spray tests?
Yes. All our CCT chambers can perform standard continuous salt spray tests as well.
What material is used for the chamber body?
We use high-grade FRP (Fibre Reinforced Plastic) or Polypropylene to ensure maximum life against corrosive solutions.
Does it require compressed air?
Yes. High-quality dry compressed air is required for salt fog atomization and drying cycles.
Do you offer scrubbers for the exhaust?
Yes. We can provide optional chemical scrubbers to neutralise the exhaust before it is vented to the atmosphere.
