Danfoss sets new efficiency standards with VSD range

Danfoss, Variable speed drives, VSDs

Variable speed drives (VSDs) in the popular and successful Danfoss VLT range are setting new standards for efficiency and compact construction.

Available in ratings from 315 to 560 kW 400 V (355 to 800 kW 690 V), Danfoss E-frame drives are up to 73% smaller than their predecessors, which allows for savings of valuable space in control panels and equipment rooms.

The new E-frame drives also incorporate an enhanced version of the Danfoss back-channel cooling concept, which now removes up 90% of the heat generated by the drive.

This heat can readily be exhausted outside the enclosure and this innovative cooling system also dramatically reduces temperature rise and contamination of electronic components, thereby ensuring long and reliable service life. In addition, back-channel cooling reduces the need for air conditioning in rooms where the drives are installed and this, along with enhanced operating efficiency of the new drives, means that big savings in operating costs can be achieved.
