Airbox T60

Casing design

The Airbox T60 devices have a thermally decoupled aluminium frame with gutters and corner connections made of fibreglass reinforced polyamide which are also thermally decoupled. Frame profiles and plastic corner connectors are sealed against each other using EPDM seals. The thermally decoupled casing panels are of double-skin construction with a 60 mm wall thickness. In the basic version, 1 mm thick galvanised steel sheet is used for the inside and outside sheets. Alternatively, the T60 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. Lifting lugs can be attached due to the decoupled frame profile exclusively on the base frame under the housing. The T60 series is Eurovent certified. The suitability for the highest hygienic standards is demonstrated by the TÜV certification to DIN1946/T4 and VDI6022.

Base frame

The units up size 10Q can be provided with a folded base frame made from 3 mm thick galvanised steel sheet. From size 13R, the devices are always supplied with a base frame. Alternatively to the folded variants, welded and primed steel base frames as well as welded and galvanised steel base frames in a weather-proof design are available from size 16R. With a combination of supply and exhaust air units arranged one above the other; the upper level is also equipped with a base frame from size 13R.

Air volume

Minimaal (V=1 m/s): 810 - 33.000 m³/h

Thermal properties

Heat transfer [W/m²K]: 0,70 (T2)

Thermal bridging factor kb: 0,60 (TB2)

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.

Module connection

The modules are connected in different ways depending on their size. The supplied self-adhesive sealing tape (40 mm x 3 mm) must be affixed to one of the two modules which are to be connected. Folded gusset plates are installed in the corners at the factory. The modules are tightened onto these with supplied screws M8 x 110 mm. In modules from unit size 13R upwards, it is necessary to set additional module connectors are to be placed along the edges of the unit cross-section.

Eurovent energy efficiency label

Specifically for the T60 series, the unit data sheet from our Eurovent-certified selection programm additionally specifies the Eurovent energy efficiency category and we put this label on the unit. Similar to the way in which energy efficiency indications have been introduced for other areas in the EU, the Eurovent energy efficiency label divides air handling units into categories A to E. In this case, a general consideration is given to characteristic values for air velocities, external pressure losses, configuration outdoor temperature, pressure losses from the heat recovery, efficiency of the heat recovery and electric power consumption of the fans, in comparison to a single benchmark, and the unit is then assigned to the appropriate energy efficiency category.
