Solar Accessories

Solar fin tubes are used in the heat absorption part of the plate collector, now there is ultrasonic welding and laser welding from BTE Solar. The ultrasonic welding is strong and durable, copper fin and copper pipes will use ultrasonic welding, which has high thermal conductivity. However, aluminum fin and copper pipes will be welded by laser welding machine, the production efficiency is higher and welding spot is more stable. At present, BTE Solar have 2 pcs ultrasonic welding machine and 4 pcs laser welding machine to guarantee the fast delivery time. Now we can offer solar absorber for the FPC factory or produce OEM & ODM solar collector for different clients.
