Product evolution


CDC developed and designed this spray fan system in the 1990s in response to increasing industry concerns surrounding dust. Testing of the original unit, conducted at the CSIR, was witnessed by industry experts. The reverse flow back flush cleaning system was developed and incorporated after additional development by CDC.
