Table 3A — Unit Operating Range*
*Maximum ambient temperature and percent of unit capacity will vary based on
unit load and return water temperature. All models are qualified for use at
125 F (46 C). Some models may require the high ambient fan option. Contact
your local Carrier representative to obtain performance data using the Carrier
electronic catalog.
†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 special order 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 us-
ing the Carrier electronic catalog.
††Requires optional or accessory low ambient kit for operation below 15 F (–9 C).
All other models require the low ambient control for operation below 0° F
(– 17.8 C)
NOTES:
1. The 30GXN,R units will start with loop temperatures up to 95 F (35 C).
2. Nominal flow rates required at ARI conditions 44 F (7 C) leaving fluid tempera-
ture, 54 F (12 C) entering water temperature, 95 F (35 C) ambient. Fouling fac-
tor 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 temperatures (below 32 F [0
°
C]).
4. Where winds of 5 mph (2.2 m/s) or greater are anticipated at outdoor ambient
temperatures below 32 F (0
°
C), wind baffles are required.
