ECo Motor™ (ECE-ST) Steam Heated Air Curtain

Steam

The ECE-ST is a steam-heated air curtain designed to maximize employee/customer comfort while helping to reduce energy costs through the use of an advanced motor that optimizes performance. Powered Aire’s ECo-Motor™ models feature electrically commutated (EC) motors that are significantly more energy efficient than traditional PSC motors. The motors are specifically designed for air curtain applications, with the time between motor activation and maximum speed less than 1 second.
