how to select air handling unit

The following questions which you can answer online below, or if you prefer by FAX (download form here) are aimed at helping you with the optimum selection of AHUs whatever the stage of your project e.g determining the approximate size of units at the preliminary design stage, costing for budgets, establishing equipment specifications for ventilation, heating, cooling, and heat recovery. ---Supply air onlySupply/extract mixingSupply/extract/heat recoveryOther If other, please specify N.B.

Additional information - requirements The following information is only requested to enable us to communicate with you clearly on this specific AHU design.
We understand that you may wish not to name the project but simply use some identifying project reference number.Swegon’s new plug-in (pictured below) enables you to install air handling units directly into your MagiCAD, Revit or AutoCAD project. Choosing the correct AHU based on project requirements and ventilation design is instant, without the need of leaving the design application. In MagiCAD environment, the plugin tracks any changes during the project design for you, alerting you to adjust the AHU and to run MagiCAD balancing calculations. As with all other Swegon MagiCAD plugins, Swegon AHU Plugin enables direct data transfer between Swegon’s calculation programs and your MagiCAD project. It includes ProUnit application, a calculation program for dimensioning and selecting air handling units. More information about using ProUnit can be found on Swegon’s webpages. This plugin is just one way that you can save headaches, time and expense further in the build. Swegon is part of the Latour group and is the market leader within energy efficient ventilation and indoor climate systems.
Through the Swegon Group sales subsidiaries and partners Swegon supplies components and systems that create good indoor climate and highly contributes to saving energy. The company has 11 production plants in Sweden, Finland, Italy, India, North America and Belgium and employs 1850 staff. The turnover is approximately MEUR 375. MagiCAD Plugins are complementary applications, enabling you to select products more easily from certain manufacturers. They also give access to a wider range of more complex products, e.g. Air Handling Units (AHUs). When the manufacturer has highly customisable products, a large number of product variants, or they want to help their customers in selecting and installing the most suitable product, a plugin is specifically developed. Close to 30 MagiCAD plugins exist and are totally free to use. The graphic below lists all the new plugins.
