Rehm Thermal Systems has launched an advanced new series of drying systems for solar cell metallisation.
The RDS 2100 and RDS 3000 offer a variety of advanced process features and thermal control that enable PV manufacturers to move their processes to an entirely new level of efficiency and yield.
The drying process consists of a combination of either five or seven IR zones and one central convection zone. This design combination offers 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 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.
