REFRIGERATION EQUIPMENT ELECTRONICALLY COMMUTATED MOTORS (ECMS)
General Requirements: Incentives are available for installing energy-efficient fan motors on non self-contained refrigerated cases which meet the requirements as described in each of the sections below. ECMs may be installed by themselves or as part of new evaporators. A manufacturer specification sheet must be attached to the application when submitted. Equipment costs must be itemized separately on invoice. Incentives are available for ECMs or brushless direct current (DC) or ECM equivalent, including permanent magnet synchronous motor (PMS) fan motors. New motors may be an upgrade or replace either shaded pole (SP) motors or permanent split capacitor (PSC) motors. EVAPORATOR FAN MOTORS Requirements: • Incentive is available for retrofit in existing display case and walk-in evaporators and when replacing existing functional display cases and walk-ins with new
display cases and walk-ins only if the old cases and walk-ins had either SP or PSC motors. • Incentive is not available when replacing non-operational display cases and walk-ins. • New motors must be designed specifically for use in evaporators. EQUIPMENT UPGRADES AND RETROFITS Measure Description

PRO TIP When upgrading to ECMs, consider upgrading the fan blades at the same time to ensure optimal operation of the fans. Many times the blades are dented or misshapen, causing the new motors to run less efficiently.
CUSTOM PROJECT IDEA Talk to your Energy Advisor about custom incentives that may be available for installing a parallel rack refrigeration system instead of individual compressors and condensing units.
