ignition-protection class „c“ for conveying explosive
gaseous atmospheres from group IIB for zone 1 and
zone 2, with MK.. external impeller motor for
explosion-prone areas, ignition-protection class „e“.
Specification: The present range includes 6 fan diameters from 154mm to 300mm and comes with all accessories that are presently used on traditional ranges: guard grill, inlet ring, bracket, etc.
Attributes and special features: The fans of the ECQ range have been developed based on motors using the latest EC technology.
With efficiency rates of up to 65%, these ECQ motors allow major energy savings. They are easy to install, have an outstanding efficiency, operate with an extremely low noise level and are fully exchangeable with traditional shaded pole motors.
Applications: The ECQ range can be used in various applications, but has been developed in particular for the refrigeration in applications like refrigerated displays or small condensing units.
