PetroControl VAP vapour recovery tester
Our very own vapour recovery tester – developed, calibrated and supported in Wallenwil.

The PetroControl VAP performs wet vapour recovery measurement according to SN EN 16321-2 (method B). The required recovery rate is 93–107 % – and the device shows flow and gas volume live.
No more handwritten records: the report comes straight out of the device as an archive-proof PDF, plus a thermal-printed receipt. 7" touchscreen (works with gloves), 50 measurements in memory, 18 V swappable battery, rugged case.
The legal basis is the Swiss Ordinance on Air Pollution Control (Annex 2 No. 33), the FOEN enforcement guide and Cercl'Air recommendation No. 22. We calibrate the gas meter, remind you of due dates, train you on site and keep the firmware up to date.
