A novel approach to refurbishment has brought 25 year old variable speed drives up to state of the art specification, yet kept them outwardly identical to the original oil-cooled units.

A quarter of a century ago drives were in their infancy, very much an emerging new technology. As such many of products from that era now seem to come from the weird and wonderful school of design, and all were terribly inefficient by today’s standards – 70-75 per cent then compared to +98 per cent now.

However many have survived to this day, faithfully and constantly executing their duties and as such are worthy of high praise. Most have been used in very aggressive environments throughout their long working lives and had the advantage of being completely water and dust proof.
