Greatest benefits of the AVA VacuDry technology

Approved treatment method operating since more than 10 years with numerous applications
Environmentally friendly, fully enclosed separation process for volatile contaminants
Single process approved to be operated with multi-contaminated input materials
High temperatures and low vacuum to ensure an in-depth cleaning effect
Lowest energy consumption through efficient heat transfer and controlled power requirements
Emission and dust free system by final, encapsulated treatment of exhaust vapours and solids
Optional stabilisation/solidification of cleaned solids after thermal treatment
