Documentation & validation

All AQUA-NOVA® stills and pure-steam generators undergo factory acceptance testing (FAT) before delivery.
Tests are documented and, when applicable, produced steam quality is verified by an independent laboratory.
Software is developed according to GAMP guidelines. On request, full Pre-IQ and OQ documentation is supplied,
including calibration records, pressure-vessel drawings, material/weld certificates, and complete mechanical/
electrical/instrumentation manuals.
