ISO certification renewed: focus on quality remains

The ISO certificate for the Koltec quality system was reassessed this year and renewed without any problems. This certificate is very important to Koltec, as it keeps the organisation focused on quality.

Quality that proves itself in practice

The result is clear: high-quality products. That is Koltec's competitive advantage. Customers and end users of Koltec products can be sure that they are choosing devices that will last a long time and remain trouble-free. This is also evident from the long-term trend: despite a growing number of devices on the market, the number of repairs and warranty claims continues to fall sharply.
