Application Viledon CRU: The ‘recirculating air filtration’ system
®
Many industrial processes generate contaminant gases that can cause corrosion. The Viledon ChemControl Recirculation Unit (CRU) is a system fully based on
®
Even minor damage to electronic components can have serious consequences, recirculated air filtration. This makes it an ideal addition for rooms that are
e. g. fault signals, unplanned downtime, high repair costs. The Viledon supplied with filtered air and maintained at positive pressure using a Viledon

®
ChemControl Recirculation Unit (CRU) and the Viledon ChemControl ChemControl Deep-Bed Pressurization Unit (CDBPU).
Recirculation Pressurization Unit (CRPU) are multi-stage filtration systems that
reliably provide complete protection against corrosion. Viledon CRPU: The ‘outside air + recirculating air filtration’ system for
®
overpressure generation
In both systems, Viledon Compact pocket filters are used in the pre-filtration

stage. Positioned before and after the fan, the Viledon ChemControl Modules Using an admixture of outside air, the Viledon ChemControl Recirculation

with pellets eliminate harmful gases. Viledon MaxiPleat cassette filters ensure Pressurization Unit (CRPU) can maintain a slight positive pressure within the room
®
secure fine filtration. Integrated pressure gauges allow for reliable monitoring to be protected. At moderate concentrations of corrosive gases, the Viledon

onsite. CRPU can be operated without the use of a Viledon ChemControl Deep-Bed
Pressurization Unit.
