These systems combine the flexibility of booth setups with the precise process control typical of tank systems. In this configuration, the penetrant is applied inside the cabin using either standard or electrostatic spraying. Key stages such as emulsifier application and the critical Stop-Off phase are conducted in tanks to ensure complete control over timing for these essential steps. Washing, drying, developer application, and inspection are performed within the cabins.

Mixed cabin-tank systems are especially popular in the Aerospace and Energy sectors, where their adaptability and rigorous control over each process phase meet the high standards required.
