Drying systems for solar cell metallization

An advanced series of drying systems for solar cell metallization, RDS 2100 and RDS 3000 offer a variety of advanced process features and thermal control that give PV manufacturers high efficiency and yields. The drying processes comprise a combination of either 5 or 7 infrared (IR) zones and 1 central convection zone.

Click to EnlargeThe drying processes comprise a combination of either 5 or 7 infrared (IR) zones and 1 central convection zone. This design combination offers temperature profiling that can be adjusted for precision and flexibility. These horizontal throughput systems guarantee a safe transport through the oven via mesh belt or 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 so that no latent heat is carried into the cooling area. At belt speeds up to 6m/min., the RDS series provides throughputs 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 process chamber is designed to be accessible for maintenance purposes. The oven opens from the front with removable sheets for cleaning.
