Sizes and air volumes
The DV Air Handling Unit (AHU) comes in a range of 14 different sizes, with air volume capacities from 0,4 - 24 m 3 /s or 1,500 -    86,000 m 3 /h, making it possible to always find the unit suitable for any given requirement .

Functions
The DV AHU features a number of well - dimensioned functions, which can be configured for many different applications, from individual fan units to advanced air handling systems .

Dampers
DV is fitted with contra - rotating dampers in tightness class 3 . The product range consists of shutoff - and mixing dampers .

Filters
Compact filters in class G4 are short pleated filters . Bag filters are available in 5 classes from G3 to F9. Locking rails ensure tightness and easy change of filters .

Heat exchangers
Rotary heat exchangers with a high efficiency level . Possibility for transferring of moisture . Plate heat exchangers for separation of airflows, and with possibility for corrosion protection . Run - around coil heat exchangers for airflows that are separated from each other.

Heating coils
For heating of air with hot water, steam or electricity.

Cooling coils
For cooling of air with cold water or direct evaporation.

Fans
Belt - driven centrifugal fans with different types of high efficiency fan impellers. Plug fans are direct driven and features low sound levels in the lower frequencies.

AHU Casing
DV Air Handling Units are built to last . To ensure that the quality of the casing lives up to the high standards of its functions, we use panels and frames which are protected against corrosion using alu - zinc of the highest quality AZ185 . Steel sheets which are protected with alu - zinc AZ185, ensure a corrosion protection in class C4 according to EN 12944 - 2 .

Frame profiles and corners
Danvent AHUs are constructed using a closed framing profile with cast aluminium corner pieces . The frame profiles are made of steel with alu - zinc corrosion protection . The result is a strong and robust construction able to resist twisting and lateral movement, making them extremely stable and strong .

Panels
The panels of the DV AHU are built using a sandwich construction with 50 mm mineral wool for sound and heat insulation . The mineral wool is completely encapsulated between two steel sheets . The panels with alu - zinc surface is not only highly corrosion - resistant, but presents an attractive, uniform appearance that can last for many years

Disc - Lock
An AHU consisting of several sections can be quickly and efficiently assembled using Disc - Lock, our unique assembly system . The sections can be assembled externally or internally as required .

Inspection Doors
Danvent AHUs have large inspection doors, making service access easy . The doors are mounted using solid hinges with easily removable stainless steel pins . This means that the doors can be easily removed, if there is no room for normal opening of the doors . The doors are sealed using rubber profiles and locks with heavy - duty handles . They can only be opened using a key, thus fulfilling the specifications of the Machinery Directive (CE Marking) .

Roof Units
The DV AHUs are available as roof units . In this version the units feature a roof construction, which provides protection against the effects of the weather . The units are available with components, which protect the air inlet and outlet against rain and snow
