Lotus Systems optimizes PV production processes

GUTMADINGEN, GERMANY: Lotus Systems GmbH, a leading manufacturer of wet process, cleaning, and chemical management systems for photovoltaic, semiconductor, and MEMS production, has developed new cleaners.

"Chemistry as an integral part of production helps to increase efficiency and lower costs," says CEO Joachim Mink with conviction. The new vertical spray cleaners allow manufacturers to clean the carriers themselves -– quickly, efficiently, and at their own facilities.

Spraying ensures that there is always a reactive medium on the surface and makes cleaning two to three times faster. Only about a tenth of the chemicals are needed, since the engineers have developed a special way to position and control the nozzles.

At about €20 per carrier, the cost of cleaning and drying is about a quarter of what it has traditionally been. Plus, the carriers are ready for use again after 12 hours. The vertical spray cleaners, with their extremely small base area of 1.8 square meters, can easily be integrated into the established production process.
