(2) TD = Condensing temperature - ambient temperature.
(3) For High Altitude applications apply the following correction factors: 0.94 for 2000 feet,
0.88 for 4000 feet and 0.81 for 6000 feet.
(4) For 50 HZ capacity multiply by 0.92. (No derate necessary when using EC motors)

ABOUT EC MOTORS
EC MOTORS
60Hz
Air cooled condensers utilizing electrically commutat-
ed motor (EC motor) technology offer many benets;
Improved Efciency, Reduced Sound Levels, Speed
Control, Simplicity and Reliability
Efciency
The speed control function of an EC motor allows the
condenser to run at optimized energy levels at different operating conditions. Up to 75% in energy savings can be realized when comparing the EC motor
speed control method to a conventional fan cycling
method. See table below for power consumption and
energy savings comparisons.
Sound
As EC motor speeds vary for different operating
conditions they also offer reduced sound levels when
compared to conventional motor running full speed.
Sound levels are reduced on cooler days and in evenings. Refer to page 15 for sound ratings at different
speeds.
Head Pressure Control
EC motors make it easier to maintaining stable head
pressures when motor speeds are varied according to operating conditions. System optimization is
further enhanced compared to the system shock from
conventional cycling banks of fans off and on.
Simplicity and Reliability
The installation and control of EC motors is very
simple compared to other methods of speed control
used on conventional AC motors. Lower running operating temperatures and smooth transitional speed
changes make EC motors durable and reliable.
