Existing Conditions

The existing compressor motors (xx, xx, and xx hp) are standard efficiency (85% efficient or less).  They are original equipment with the plant and may have been rewound one or more times since they were new.  A motor becomes less efficient each time it is rewound.

Retrofit Conditions

Replace the existing motors with high efficiency motors (HEMs).  HEMs are typically 2% to 8% more efficient than a standard efficiency motor, which becomes quite significant in motors of this size.
