Increased productivity while meeting low energy consumption within smaller footprints are required for inline c-Si solar cell equipment to meet the lowest cost of ownership as part of cost per watt reduction strategies. Improved thermal control can also lead to improved cell efficiencies and higher yields.
Solution
The Solardryer RDS 2100 and RDS 3000 drying process consists of a combination of five IR zones and one central convection zone, offering temperature profiling that can be adjusted for both precision and flexibility. These horizontal throughput systems guarantee a safe transport through the oven either via mesh belt or with pin chain up to 3 lanes. In the mesh belt systems, the conveyor of the heating zone can be separated from that of the cooling zone. Consequently, no latent heat is carried into the cooling area which offers a higher cooling gradient and a shorter oven. And at belt speeds up to 6m/minute, the RDS Series provides high throughputs of up to 5700 wph. The low-maintenance concept used for these systems, as well as low energy consumption, high throughput levels and intelligent software solutions is designed to provide low cost of ownership.
Applications
Solar cell metallization processes.
Platform
The new systems are also available with Rehm’s Condensate Residue Management System, a process that controls the buildup of unwanted paste solvent and vehicle residue in the process chamber and extends the maintenance intervals. The entire process chamber of the RDS Series drying systems is designed to be readily accessible for maintenance purposes. The oven opens from the front and comprises removable sheets that can be easily removed for cleaning, significantly reducing the maintenance time and effort. All systems are equipped with shortwave IR radiators for heating at the top and bottom.
Availability
September 2010 onwards.
