Philips Drachten is one of the biggest development and production centers in Europe within Philips. It is a globally oriented site. On this site, employees from all over the world collaborate enthusiastically on the development of products that improve people’s lives. The Drachten site develops numerous innovative products, such as Senseo coffee machines, Ladyshavers, vacuum cleaners, beard trimmers, hair clippers, Wake-up Lights, and shavers. Besides developing new shavers, Drachten also produces them in a shaver factory that uses cutting-edge production technology to manufacture the latest shavers 24/7. Philips Drachten has 2000 employees from 35 nationalities, including 600 development engineers.


The assignment is about scale and scaling from (hard) waters in steam irons, coffee-makers etc.

Particularly when water is heated and converted into steam the scale formation and precipitation is not fully understood. A thorough understanding of the involved chemical and physical processes is needed to find ways to improve the performance of domestic appliances in this respect.

Many hypotheses exist around scale formation and precipitation in domestic appliances. Some of these hypotheses we would like to investigate in order to accept or to reject them.


The overall approach is to make yourself familiar with (drinking) water quality, scale formation and precipitation processes as take place in domestic appliances.

You need to check a few existing hypotheses by setting up and conducting smart experiments taking the use and operational conditions of steam irons into account.
