ACCA Updates DuctWheel App, Available For New Low Price

Posted on:

ACCA, the nation’s largest association of indoor environmental systems professionals, announced that it has updated its DuctWheel app. The updated app allows the DuctWheel to display clearly on newer iPads that have higher resolution retina display screens.

And for a limited time, the app is available for a new low price of $9.99 through the Apple iTunes App store. If you have already purchased the DuctWheel app, you will be able to update it at no additional charge.

ACCA DuctWheel is a mobile version of ACCA’s popular Duct Sizing Slide Rule, which is used by contractors nationwide to determine proper sizing of residential duct systems in accordance with Manual D, the national accredited standard for residential duct design. Using the DuctWheel app instead of the standard duct slide rule, contractors and designers can lock the wheel in place, zoom in for easier reading, flip between two wheels for different calculations, or take a screenshot of the wheel in position.

Contractors can use the app to: size lined and unlined metal ducts, duct board airways, and wire helix flexible ducts; convert round shapes to equivalent rectangles; correlate available pressure with total effective length and friction rate (Manual D sizing calcula­tions); convert velocity into velocity pressure and vice versa; and correct for altitude and temperature. An instruction guide is included with the app purchase.

The ACCA DuctWheel app works exclusively on iPads using iOs version 4.2 or higher, and is available for the new low price of $9.99, for a limited time, at the Apple iTunes store.
