About this app
This quick and simple-to-use app will assist gas engineers in calculating the maximum time required to purge air from a non-domestic natural gas installation, allowing the appliances to fire correctly.
Suitable for natural gas (NG) installations only, with an installation volume not exceeding 1m³, and a maximum operating pressure (MOP) not exceeding 40mbar at the outlet of the primary meter regulator. Calculations are performed in accordance with IGE/UP/1A Edition 2 and are intended to help you double-check your own calculations.
If you also require the tightness testing duration (TTD) for the system, the option to calculate this is available to purchase in-app.
For the busy multi-client gas professional, there's an option to purchase a Save Installations add-on allowing you to save and retrieve installation layouts for future reference.

Hi, could you please contact me at support@speaktothegeek.co.uk with your worked example so as I can reproduce the problem. Your assistance in resolving this will be greatly appreciated as current test scenarios are not showing any errors.

DO NOT USE THIS. We all know how accurate these calculations need to be, but this app gives incorrect figures and calculations. Stick with your IGEM)UP1 &1A or you could be in serious trouble using this.

Hi, would you be able to contact me at support@speaktothegeek.co.uk with an example calculation you have done where the app is providing you with an incorrect result? I'd very much like to get to the bottom of that problem because all test scenarios I have put into the app come out as accurate.

Outdated, shows a 10% allowance for fittings when you now have to count each type of fitting and make the corresponding allowance.
