These handy devices/programs allow you to calculate Areas, Velocities, Flowrates, Pressure Losses and a load more design criteria either using a simple hand held circular slide rule type device …. or more recently apps for your Android or Apple device.
- Ductulator – Duct Sizer £4.99 Ductulator – Duct Sizer. For the manually operated (well known) circular Trane Ductulator – you will need to search eBay. It will probably be eBay USA (where I bought mine) but even with shipping the total cost was around £16.
- The simplest and quickest ductulator app there is! Now avaliable in SI and Imperial units! Ever wished you had your classic slide ductulator with you on-site, in a meeting or at your desk?
- HVAC design tools include such popular items as the Trane Ductulator™, psychrometric charts, and load estimating forms. Learn more about the order process here. Ductulator - Hand held rotating calculator used for sizing supply and return duct systems using the equal friction design method.
- Trane 360 ° is a mobile application designed for today’s on-the-go service professional. Get instant, easy access to all the information you need in one convenient place – without having to make phone calls or use multiple websites. All information is in real time. From sales to support staff, anyone in your office can use Trane 360°.
Think of this application as a digital version of the classic Trane Ductulator. In the 'Size by Airflow' mode, you can specify the total airflow in CFM (or L/s), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters).
I have not personally tested the latter and would welcome feedback on anyone who has. Some of the web feedbacks on these are not good – but the ones selected below appear to have reasonable feedback.
