Carrier’s electronic catalog chiller selection program pro-
vides quick, easy selection of Carrier chillers. The program
considers specific temperature, fluid, flow requirements,
system pressure drop (for proper pump selection, when
required), as well as other factors, such as fouling and alti-
tude correction.
To select a 30RAP chiller, including optional pump
package when required, use the NACO (North American
Commercial Operation) Packaged Chiller Builder Program.

*Option Code refers to the Hydronics Option (position 12) in the model
number. See the 30RAP nomenclature on page 4 for option identifica-
tion.
NOTE: Pump selections are chiller size dependent. For example, option
code 5 on a 30RAP010-030 chiller is not the same as option code 5 on
a 30RAP035-045 chiller.
