ALUFER Firetube Technology Animation

The ALUFER tube provides exceptional heat transfer design. The tube is constructed from an inner (fireside) aluminum alloy finned surface and die-fitted within an outer steel tube.
• Thermal conductivity is 10 times greater than stainless alone
• Fireside is divided into 10 flow channels for maximum heat transfer
and condensing performance
• Provides the maximum effective heating surface where it is needed
the most
• Heating surface up to five times larger than other condensing boilers
