App Description

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 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.
