Danvent DVA modular air handling unit

The Danvent DV 190 and 240 are designed as modular air handling units. Each function is placed into an air handling unit casing consisting of one or more modules. The modular functions can be confi gured for many different applications to make up the heart of any ventilation system.

The Danvent DV 190 and 240 are continually being opti­mized and added improvements. The result is extremely flexible air handling units, both in terms of design and function.

The air handling units are produced in Denmark. At the Danish Systemair factory we have manufactured air hand­ling units since 1977. Systemair in Denmark houses the group’s expertise for large air handling units. We focus on development, manufacturing, sales, and consultations.

Functions

Sizes and airflowsThe Danvent DV comes in a range of 14 different sizes, with airflow capacities from 0,2-24 m3/s or 750-86.000 m3/h. The sizes DV 190 and 240 are the largest units. The wide range makes it possible to always find the unit optimized for any given requirement.

FunctionsThe DV 190 and 240 feature a num-ber of well-dimensioned functions as standard. The functions facilitate easy handling on the building site and easy service access as well as ensuring high efficiencies and long service life.

Dampers The dampers in DV 190 and 240 com-ply with EN 1751:2014, sealing class 3. The dampers ensure a long and trouble-free operation, as the blades are mounted on sturdy square profile shafts and service-free synthetic bearings with large bearing surfaces.

FiltersIn the DV 190 and 240 the filters are held in separate frames with effec-tive springs. This also applies for DVG pre-filters.

Heat exchangersThe DV 190 and 240 are available with rotary heat exchangers which are always supplied divided. The DV 190 and 240 are also available with run-around coils.

Heating and cooling coilsThe DV 190 and 240 are available with coils for hot water and chilled water. A drip tray is standard for the cooling coils.

Fans2 directly driven plug fans for fre-quency control are standard in the DV 190 and 240 (frequency converters are optional). By using 2 fans an even distribution of the airflow is ensured on the entire width of the unit.

Wall with EC fansFans with EC motors are available. The desired airflow can be achieved with the parallel running of up to 5 EC fans in each airflow. The fans are distributed in a way that ensures an even distribution of the airflow in the unit. A minimum of space is required for the wall of fans and thus the building length will be shorter accordingly.

SystemairCADThe product selection programme, SystemairCAD, ensures optimal design of the air handling unit functions. The programme is very user-friendly and makes it possible to quickly and easily combine air handling unit functions and perform technical calculations.

Functions

SystemairCAD calculates and opti-mizes the energy consumption and the calculated data are the basis for Eurovent certification and energy classification of Danvent DV.

The programme uses a number of combination examples or basic ver-sions. From these examples one can quickly add or remove features in order to easily design the desired air handling unit.

The drawn to scale drawings plus logical construction and presentation of technical data provide easy over-view. The drawings can easily be exported to other CAD software. SystemairCAD has plug-ins for the CAD software MagiCAD for AutoCAD and Revit. The plug-ins make it pos-sible to insert Systemair air handling units directly into MagiCAD, AutoCAD, and Revit. SystemarCAD can be downloaded from systemair.com.

Casing The DV 190 and 240 are built to last for many years. The frame profiles and panels are made of steel sheets protected with alu-zink AZ 185 – pro-viding a good corrosion protection.

Frame profiles and cornersThe DV 190 and 240 are constructed using strong, closed and all-welded steel framing profiles. With the cast aluminium corners the result is a strong and robust construction able to resist twisting and lateral move-ment, making the units extremely stable and strong. PanelsThe panels of the DV 190 and 240 are built using a sandwich construc-tion with double sheets and 50 mm mineral wool for sound and heat insulation. The panels with alu-zinc surface are not only highly corrosion-resistant, but present an attractive, uniform appearance that can last for many years. Steel sheets which are protected with alu-zinc AZ185 ensure a corrosion protection in class C4 according to EN ISO 12944-2:2000. Base frame and sectionsAll DV 190 and 240 sections have a strong and rigid base frame with lift-ing brackets. Some sections may contain more than one function, and these sections will have their own base frames. The base frame is part of the casing, and it is not possible

to demount the base frame. Also for units in 2 levels (supply air and exhaust air in 2 levels) the base frame is necessary under the upper casing to keep the whole unit rigid, and it will ensure easy transport.

Assembly of sectionsThe lifting brackets are removed from the base frames and the base frames are bolted together. Brackets keep the top of the sections together.

Inspection doorsThe DV 190 and 240 have large inspection doors, making service access easy. The doors are mounted using solid hinges with easily remo-vable stainless steel pins. The doors are sealed using rubber profiles and locks with heavy-duty handles. They can only be opened using a key.

Transport and liftThe length of each section does not exceed 2470 mm. For easy internal transport with a fork-lift truck with extra long forks, 100 mm high wood blocks are bolted under each corner of the base frame.

NOTE! Do not under any circumstan-ces lift the section with forks that are shorter than the section!

When the sections are lifted by straps to the final de stination, it must be carried out by using the lifting brackets on the base frame, and dis-tance pipes must be used above the section.Ready to lift. Base frames are connected.

Danvent DVA modular air handling unit

To ensure optimal dimensioning and configuration of the air handling unit’s functions, we have developed the design programme SystemairCAD. The programme is very user­friendly and facilitates a simple and quick way to combine unit functions as needed.

When you have completed the design of the air handling unit, SystemairCAD automatically performs all technical cal­culations and documentation. The technical documentation is presented as a pdf­report specifically for the chosen air hand ling unit. SystemairCAD can also generate a complete specification text that is easy to adjust and copy to the tem­plate of tender. This ensures that all values are correct.

Systemair Plug-insThe drawn to scale drawings from SystemairCAD can easily be exported to other CAD software. The plug­ins make it pos­sible to insert Systemair air handling units directly into MagiCAD, AutoCAD, and Revit. This makes it fast to connect the air handling unit to the ducting of the drawing in the overall BIM model. SystemairCAD is free for download on systemair.com.

You are always welcome to call your local Systemair office for technical guidance or quotations.
