NC-2009 EAc1:Optimize Energy Performance

Cooling tower's motor

Cooling tower's performance is covered in 90.1 Table 6.8.1G, but does its motor have to comply with Table 10.8 Minimum Efficiency for Motors?

The efficiency requirements in Table 10.8 are law in the US. It is not legal to make motors with lower efficiencies. So if the cooling tower motor is covered by the law it should be in compliance. If outside the US, if the cooling tower motor is covered by the motor type in the table then yes it would need to comply.
