Enclosures

Air cooled compact cabinet Double-side service zone Designed to combine the smallest footprint layout with the full performance of a standard drive without any compromises on power or quality. An ideal solution for retrofit projects or any installation with space constraints.
Air cooled standard cabinet Single- and Double-side service zone Classic Line up version with design optimization for an overall reduced switch gear width. Power cell cabinet with cell installations from the front and the backside of the cabinet. This switchgear version is a perfect fit for applications with multiple drive installations.
Multi drive system standard cabinets Single-side service zone only Distribution switchgear style with a single side service access design. This type of VFD is ideal for a wall mounted or back to back installation. It is often used in single installation sites or smaller rooms with a certain limitation of switchgear depth.
Water cooled cabinet Single-side service zone Water cooling provides uniform heat distribution that guarantees lower component temperatures and longer service life. The fully enclosed air-water heat exchange type enclosure provides insulation from outside temperatures and dust.
