Cooling tons based on 12,000 BTU/Hr/ton with 50°F leaving coolant and 95°F ambient air.
2
Sound power shown is for standard high-efficiency constant-speed AC motor fans. A high-pressure variable-speed EC motor
fan option is available for NQA08 and larger units that changes the sound pressure at 1 meter (dBA) to 75 for NQA08-10, 82
for NQA15, 84 for NQA20, 85 for NQA25, and 82 for NQA30.
3
Net available pressure at outlet of chiller is pump discharge pressure less the internal coolant-circuit pressure loss.
4
MCA is Minimum Circuit Amps (for wire sizing), complies with NEC, Section 430-24.
