STEINEL as a one-stop-shop partner

Hot air hair dryer reinvented thanks to sensor intelligence

A Swiss quality product with tradition – Thanks to high-frequency sensor technology from STEINEL, the hot-air shower becomes intelligent.

The Vendaval hot-air showers from the Swiss company Rez AG stand for genuine Swiss quality and durability. The hot air showers for use in public, institutional areas set the standard in reliability, quality and functionality. Thanks to the use of high-frequency sensor technology, the traditional devices have been revolutionised. The specially adjusted sensor technology has been optimised in such a way that the devices switch on intuitively or remain switched off when a person merely walks past them.

High durability and low maintenance costs are the hallmarks of the Vendaval units.

STEINEL Solutions supported the customer throughout the entire product development process - from consulting, product development and approval to industrialisation and production.



  • Very high-quality mechanics, robust and reliable electronics
  • Vandal-proof housing without openings for sensors or switches, which prevents damage
  • Non-contact high-frequency sensor system with automatic timer (2.5 minutes)
  • Precisely adjustable detection range (0-20cm)

High frequency


«STEINEL Solutions was able to support Rez in particular with electronics development and sensor expertise. They succeeded in producing very robust and reliable electronics that met our requirements. In the meantime, we can look back on many years of operation of the Vendaval series and can say that the electronics and sensor technology work reliably. Development and production "made in Switzerland" is a matter close to our hearts and we are glad to have the right partner at our side in STEINEL Solutions.»
