The DC INVERTER ES compr<strong>es</strong>sor reduc<strong>es</strong> the noise level to a minimum.<br />

The neodymium magnets in the rotor of the DC compr<strong>es</strong>sor improve the<br />

performance of the compr<strong>es</strong>sor at low frequenci<strong>es</strong>, and a significant reduction of<br />

electromagnetic noise has been achieved by separating the rotor into two parts.<br />

The combination of scroll compr<strong>es</strong>sors and an insulating cover provide minimum<br />

noise levels.<br />

1.4.3. Silent fan<br />

The DC INVERTER ES units have been d<strong>es</strong>igned with a fan that reduc<strong>es</strong> the<br />

noise level to a minimum.<br />

The ventilation system has a revolutionary three-blade fan. This fan is much more<br />

aerodynamic than earlier models. It has a greater surface area in contact with the<br />

air and a better turning angle, preventing turbulence and allowing the ventilator to<br />

be fitted lower.<br />

At the same time, the use of DC motors with PWM control increase the system's<br />

efficiency and reduce electromagnetic noise.<br />
