A wide range of solutions for continuous strip treatment

Fives’ solutions for pre- and post treatment adapt to the customer’s process:
•    Horizontal or vertical 
•    Combined technology
•    Compact and flexible 

A range of Stein drying ovens incorporates energy saving features, easy threading and maintenance access, as well as an instrumentation & control system with all the necessary safety devices. The recovery recirculation system uses a thermal oxidizer recuperative or regenerative system to save energy, avoid any solvent condensation and to treat the fumes by eliminating volatile organic compounds during an organic coating process.
