Unit Construction

  • Netfil air-handling units are based on a self-supporting frame structure. Their modular casing design, with individual compartments comprising various functional assemblies, ensures that each unit matches individual application requirements perfectly.
  • Although materials may vary with the unit size and application, all AHUs are of a similar construction; namely an outer framework of posts, assembled using knock in corners, into which double skin, insulated enclosure panels are fitted to form a rigid, airtight compartment.
  • Double skin insulated panels are available in 25mm and 42mm thick with uniform density of 38-42 Kg/m3. Various options are available such as pre-coated colour galvanized sheets, plain galvanized sheets, SS304 & SS316 sheets in various thickness for inner & outer skin.
  • Smaller units can be supplied as a single section, whereas larger units are usually supplied in modular form, split into manageable sections for final assembly (bolting-up) on site.
  • AHU sections are generally supplied with a sturdy channel base support frame, complete with lifting holes to facilitate craneage.
  • All internal components, such as the fan and motor assembly, are built in to the unit sections and are provided with access or removable panels, if necessary, to facilitate maintenance and removal.
  • All forms of component commonly utilised in air handling equipment can be incorporated into the design such as filters, heaters, coolers, humidifiers, attenuators, plate heat exchangers, thermal wheels and run around coil heat recovery systems.

Functional Assemblies

Droplet separator is a device to prevent the dropping liquid carrying away with the air stream. It appears as manifold bent SS304 plates installed at the outlet of cooling and heat recovery units. Drop separation is effected due to multiple change of air stream direction in the plate bending. Water drops accumulate on blades and then flow into the drain pan.

 

 

Fan Section contains belts driven DIDW Forward / Backward / Aerofoil Backward curved Centrifugal Blower & direct driven Plug Fans as per requirement . AMCA certified Fans with higher efficiency and low noise levels Fan and Motor assembly mounted on common base frame of Extruded Aluminium
