*For applications requiring cooler leaving water temperature operation at less than 40
F (4.4 C), the units require the use of antifreeze and application may require the brine
option. Contact your local Carrier representative for more information.
†For applications requiring cooler entering water temperature operation at less than 45
F (7.2 C), contact your local Carrier representative for unit selection using the Carrier
electronic catalog.
** For minimum cooler flow rate with brine applications, refer to E-CAT software perfor-
mance.

NOTES:
1. The 30XA units will start and pull down with loop temperatures up to 95 F (35 C).
2. Nominal flow rates required at AHRI (Air Conditioning, Heating, and Refrigeration In-
stitute) conditions 44 F (7 C) leaving fluid temperature, 54 F (12 C) entering water
temperature, 95 F (35 C) ambient. Fouling factor 0.00010 ft
K/kW).
3. To obtain proper temperature control, cooler loop fluid volume must be at least 3 gal/
ton (3.23 L/kW) of chiller nominal capacity for air conditioning and at least 6 gal/ton
(6.5 L/kW) for process applications or systems that must operate in low ambient tem-
peratures (below 32 F [0° C]).
