The VW3AE0921 is an air conditioning unit designed for Altivar floor-standing enclosures with separate air flows or compact versions, part of the Altivar 71 Plus and Altivar 61 Plus drive ranges.
Sourcing Reality
For a buyer filling a BOM line or maintaining an existing Altivar installation, the procurement path is a last-time-buy or surplus search — not a standard catalog order.
This unit is specifically intended for Altivar floor-standing enclosures, the type used in larger drive installations where separate air flows or a compact enclosure version is specified. It is an enclosure accessory, not a standalone drive component. The Altivar 71 Plus and 61 Plus ranges are variable-speed drives for industrial motor control; the air conditioning unit manages thermal load inside the enclosure to keep drive electronics within rated ambient limits.
What to Expect When Sourcing
A buyer seeking a drop-in replacement should verify enclosure dimensions and airflow requirements against the original installation — a parametric match from a different manufacturer or a newer Altivar enclosure accessory may be needed.
