Large air volume air handling unit Airbox S60

S60 units have a frame made from rolled, galvanised steel profiles and corner connectors made from die-cast aluminium or fibreglass-reinforced plastic. The aluminium die cast corner connectors can be supplied with or without M20 threads in order to attach crane lugs, for example. Frame profiles and aluminium die-cast connectors are sealed against one another by EPDM seals. The panels of the casing are a double-skin construction with a 60 mm wall thickness. In the basic version, 1.0 mm thick galvanised steel sheet is used for the inside and outside sheets. Alternatively, the S60 casings are available with plastic coating (standard RAL 7035), in V2A 1.4301 or with aluminium panelling AlMg3. The rock wool used as thermal and acoustic insulation is non-flammable and is partly glued onto the double-skin panel. The panels are screwed on to the hollow frame profile from the outside. The connections between the casing components are configured so the insides are smooth. S60 devices are suitable to meet the hygiene requirements of VDI 6022. Base frame The units up size 13Q can be provided with a folded base frame made from 3 mm thick galvanised steel sheet. Alternatively, welded and primed steel base frames as well as welded and galvanised steel base frames in a weather-proof design are available for larger sizes. Panel connection The panels are screwed onto the connecting profile from outside. In order to provide a good visual look, the screws on the outsides of the casing are concealed. A sealing strip is glued between the panels and profile.
