Compact Type A, size:4 x 20, 1763 sq in, copper tubes 

Compact-A exchangers are single pass on the shell side

Compact-A exchangers are single pass on the shell side, 3 pass on the tube (raw water) side. These exchangers have no expansion tank integrated into their design, and rely instead on an external expansion tank or an overflow recovery bottle to capture coolant volumes which exceed system capacity in operation, and return them to the cooling system when it cools down. Coolant is added to the system via a separately mounted fill neck with pressure cap. The shell is completely packed with tubing, providing the maximum heat transfer surface possible for each set of external dimensions. This exchanger is illustrated without a mounting bracket. We have mounting brackets for virtually any mounting configuration. The exchanger is mounted on the bracket with cushioning material
