Quality and Certificates

Measurable quality from production to service

Quality and Certificates

Quality starts with every part that touches water. In production we use only food-grade materials suitable for contact with water for human consumption: polypropylene filter housings, stainless steel pump heads and food-grade seals.

Management system certificates

  • TS EN ISO 9001 Quality Management System
  • ISO 14001 Environmental Management System
  • ISO 45001 Occupational Health and Safety Management System

Product testing

Every home unit passes a 30-minute pressure and leak test before shipment. Membrane modules are sampled for salt passage and flow; results are archived by serial number. Industrial systems are pre-commissioned at the factory and handed over at the customer site after a performance test.

Laboratory

In our Gebze laboratory we run TDS, conductivity, pH, hardness, turbidity, chlorine, iron, nitrate and COD analyses. For microbiological analyses we work with accredited partner laboratories.

Warranty and assurance

Three years on home units and two on industrial systems, with a ten-year spare-parts commitment. Warranty terms can be downloaded from the Catalogues and Certificates page.
