Core, cooling capacity is increased 30%. The core of the radiator is welded in vacuum brazing furnace, no epoxy. The tanks are 100% welded by TIG.
The material of the radiator is the same as aircraft manufacture material. Our radiators are built with 2-rows of 1" cooling tubes, not the 3-row gimmicks with TINY 5/8" cooling tubes. These 3-rows are a gimmick!
A 2-row of 1" tubes has 2" of tube-to-fin contact area (1" rows x 2 rows = 2"). These 3-row radiators only have 1.59" of tube-to-fin contact area (3 rows x 0.531" = 1.59).
Also check out the core thickness - our core is 2-3/4" thick - the 3-row gimmick radiators are only 2-1/16" thick. A 2-row with 1.0" tubes has 26% more heat transfer surface area alone than these 3-row gimmicks with 0.531" tubes. That's a HUGE difference! We never copy from another company's catalog or website.
