From the entry of the components into the warehouse, SLCE watermakers carries out strict control at all stages of production.

All parts delivered by our suppliers are controlled as soon as they are received to certify their conformity; materials are analysed using a mass spectrometer. A barcode system then ensures the traceability of the stored products.

From the simplest to the most complex, all equipment are tested on a test bench before packaging:

  • Test with raw water similar to that specified at the order.
  • Control of operating parameters: power consumption, conversion rate, pressures, flow rates, conductivity of the water produced…
  • Customers are invited to participate in factory acceptance tests where a training session may be associated.
