Derating of Pump Motors at Higher Altitude 4

[vecnaj1978]

Hello Everbody

I need a suggestion on the installation of pumps at Higher altitude

I need to install a Chilled water pump at an altitude of 2200 Meters above sea Level, The motor i am using is an TEFC AC Induction motor. The motor Manufacturer recomends to derate the mtore if the installation is above 1000 Above sea Level
Since this is all about the avialablilty of air at Higher Altitude and the motors needs to be derated

My question is if i install these pump in an airconditioned space,Do i still need to derate the Motors

If yes then please let me know the reasons and if no the wat is the reason

Thanks in advance for our Sugessions

I agree. That's why I'm having trouble working out why one of those links suggest the SF is reduced from 1.15 to 1. It would not seem to be necesary solely by examining the thermodynamics alone.
