APPLICATION FOR CHILLED WATER COIL
in case of using a water cooler installation. (chiller)
APPLICATION FOR HOT WATER COIL
Used in the event of access to water heating installation (Local boiler OR heating system) heating the supply air to the room.
APPLICATION FOR DIRECT EXPANSION COIL (DX)
In case of using generator with direct expansion of the cooling medium.

No. of rows available:2-12
Seamless M.S. and Copper headers, sized to minimize water pressure drop. With die-formed holes that provide a parallel surface to the coil tube for strong brazing joints
Connection / Circuits
AAC provides different types of circuits like Quarter circuit, Full circuit, Double circuits
Testing and Performance
All coil assemblies are tested with water at 1700 PSI
All coil assemblies are tested with Nitrogen filled at 300 ib/in2
AAC makes coils that provide two or more rows that are based on counter flow of water with respect to airflow. The mechanical expansion provides an efficient bonding of copper tube and fins for better heat transfer. Tubes are staggered in the direction of airflow.
