The 7.5 KW high-performance dryer is needed because several field studies under real conditions showed that with a lower drying performance, the washers would not use the self-service drying system again. For this reason, the concentrated know-how of KTM Technologies was combined with the vision of AIRFFECT. The costs incurred during drying are very low due to a “soft starter” which keeps the starting current as low as possible. Furthermore, the turnover compared to electricity costs is many times higher.
