SPECIFICATION
DFRA series air desiccant dehumidifier, rotor type, with high efficiency silica gel desiccant rotor for a long life and
low energy consumption.
KEY FEATURES
• Basic module casing designed as a self-supporting and compact unit. Manufactured in galvanized steel plate with
phosphate priming coat and RAL7035 enamel finish. Including sealing gaskets, component and manhole cover
plates to easy unit maintenance and inspection. Double wall insulation panels (Th>25mm) all around plates in
reactivation/wet air in contact with process/dry air. Corrosion protection according to C3 class as per ISO 12944.
• Process air intake flow manual regulation damper made of aluminium. Differential pressure takes for manual
regulation of exact air flow as a second reading to the VFD.
• Type V process air filter, synthetic fiber made, G4 classification (EN 779: 2012).
• Rigid bag process air filter, glass micro fiber media with plastic frame, F9 classification (EN 779: 2012). Housing
constructed using aluminium profiles, insulated by 25mm double wall panels.
• Desiccant rotor made of inert, fire-resistant, hygienic, high performance silica gel material, which is thermally
and chemically stable to prevent deliquescence. Including perimeter and radial sealing gasket. Rotation driving
system by gear motor for the rotor with a pulley and V belt dragging system for the perimeter transmission with
tensioner.
• Post-cooling coil by chilled water. Made of copper tubes and aluminum fins. Housing constructed using
aluminium profiles, insulated by 25mm double wall panels in same finishing. Condensates tray with threaded
drainage coils and stainless steel material in all wet-parts.
• Process fan: Single inlet centrifugal fan direct driven for the continuous extraction of air stream up to 110⁰C.
Forward curved centrifugal impeller, manufactured from galvanised sheet steel painted with epoxy polyester.
Three phase motor with thermal protector.
• Type V reactivation air filter, synthetic fiber made, G4 classification (EN 779: 2012).
• Rigid bag process air filter, glass micro fiber media with plastic frame, F9 classification (EN 779: 2012). Housing
constructed using aluminium profiles, insulated by 25mm double wall panels
• Stainless Steel tube reactivation air heater with aluminium fins, for steam at a maximum operating pressure of 8
kg/cm2 (7 bar[g]). Flanged connections, DIN2633.
• Reactivation fan: Single inlet centrifugal fan direct driven for the continuous extraction of air stream up to 110⁰C.
Forward curved centrifugal impeller, manufactured from galvanised sheet steel painted with epoxy polyester.
Three phase motor with thermal protector.
• Advanced Control panel with HMI display controller for real time monitoring and control of all components of
the dehumidifier, prepared for internal and external signals, setting a proportional humidity control, acting on a
installed solid state relay resistances or reactivation fluid control valve. Electrical panel in galvanized steel epoxy
painted assembled to the unit. Including isolator switch and appropriate internal magneto-thermal protection of
receivers and internal wiring. All as per EU security regulation, complete monitoring and easy service. Includes
manual / auto selector, on / off remote switch, remote signaling card through 3 free dry contacts: Power / Fault
(includes rotor stop alarm). Intelligent turning-off. 24 V voltage for control and supply. Profibus DP communication
option available.
