LKY Wartungs- und Industrie-Service GmbH, a renowned service partner for industrial companies, repeatedly had problems with water drops adhering to containers after the drying phase.
The thirty-meter long Everest Tunclean car wash was evaluated at the Regensburg site together with the partner company ITR Anlagenbau from Pettendorf, a specialist in process optimisation. In particular, the interaction between the chemical and mechanical components was analysed.
ITR Anlagenbau first cleaned the system thoroughly so that reproducible results could be achieved in the cleaning tests carried out. A variety of surfactant combinations and drying agents were used in the continuous washing system in several series of tests and their run-off behaviour was compared.
The especially low-foaming surfactant combination of Caramba I-Line AD-10 increased the mechanical cleaning components and achieved the best result in the spray procedure due to optimal wetting of the parts. The Caramba I-Line XN 35 plastic dryer then shone with the best run-off performance after rinsing.
Switching to Caramba products significantly increased the performance of the component cleaning system. On the one hand, it was possible to reduce the foaming that hinders the wash process and to extend the service life of the cleaning bath thanks to the highly effective demulsifiers in Caramba I-Line AD-10.
On the other hand, Caramba I-Line XN-35 XN plastic dryer delivered a fantastic drying result. Combined together they provided a cleaning result that does not need improvement in terms of cleanliness or drying.
