What does the 21 in the heat exchanger model AJ21S mean?

I understand what AJS is, but I’m a bit confused by the 21 added in the middle – does it refer to the number of inlet and outlet ports on the shell side? Or is it the number of repetitions?

The number 21 in the heat exchanger model AJ21S is probably incorrect.

J21 is a condenser with 2 inlets and 1 outlet; it seems to be denoted using TEMA notation

It is two in and one out, or one in and two out; in effect, this is equivalent to dividing the heat exchanger into two parts with a partition, although it is also possible to omit the partition in the middle.
