Aluminum Units


Fin Production: Coils of aluminum are processed through fin machines.


Core Assembly: Tubes and fins are stacked into a fixture.


Brazing: Active uses a controlled atmosphere furnace. This process allows for consistent temperature across the core which facilitates robust final joints.


Copper and Brass Units


Header Production: A technician programs a CNC machine to punch a pattern of tube slots into sheet brass


Fin Production: Coils of copper are processed through fin machines


Core Assembly, Flat Fin:

Fins are loaded into an assembly fixture

Tubes are manually pushed through a series of fins


Baking: After assembly, the core is baked in a natural gas process oven


Soldering:

Each header is dipped into a pot of molten solder to seal every tube to header joint

Technicians reinforce common stress areas for extra strength
