Dear All,

I need your feedback on the experience in implementing Auto-Variable Pitch for greenfield applications of forced or induced draft coolers. I believe it can offer a degree of air flow control but do have some reliability issues.

Appreciate sharing your experience or any lessons learnt on the same.

Regards,

I don't have experience with it but I heard from some air cooler vendors that they are hard to maintain and the pitches don't always match the set points.

Any consideration in using VFDs to control air flow? Those are pretty standard.
