Glass Washers

Glass washers are essential in assuring the module frontside glass (coverglass) is perfectly clean before laminating. All dust, residue or fingerprint needs to be completely removed before lamination to avoid delamination problems.
An even higher level of cleanliness is desired by thin film PV manufacturers as the glass needs to be absolutely clean before coating it with the thin photoactive layers by means of ECVD or sputtering processes.

Billco has more than 60 years of experience building glass washing and glass processing equipment for the window and architectural glass industry. All our machines are completely built in house and ruggedly designed for 24/7 trouble-free operation. Special attention is being paid to make all wear parts easily accessible and interchangeable. We became involved in the PV industry in 1995 and have many years of experience, especially building critical cleaning washers used in the thin film PV industry.

Billco Washing Machines come in many different models for different applications and different cleanliness requirements (thin film / crystalline modules), and different glass sizes. As an important feature we offer a variety of water filtration and water saving options up to completely closed loop “Zero Consumption” systems, which will dramatically reduce your operational costs.

As a true one-stop-solution you can purchase the detergents used in Billco washing machines directly from us.

In addition to the washing machines we are offering a broad range of professional equipment for glass handling, laminating and insulation applications.

All our machines are built to order, an experienced team of engineers can customize your system to meet your requirements. We offer service and installation locally in North America, Europe and Asia. We are looking forward to hear your requirements.
