Blockfin is the SA Heat Exchange patented method of fin to tube assembly. The bond is mechanical which enables us to use a range of fin and tube material that most other fin tube manufacturers cannot. This type of assembly is much more robust and therefore perfect for industrial applications, especially in African conditions.
