Fit pre-filters sized to the dust load and schedule cleaning before pressure drop rises above the design margin. Where the exhaust carries fibers or sticky particulates, choose wide-spaced plate channels or a heat-pipe bank that is easy to wash. A variable-frequency drive on the supply fan lets throughput follow the production rate, so recovery scales with demand instead of running flat out. Condensate from the cooled exhaust must drain safely and clear of the product zone. For continuous lines, consider N plus one fan redundancy so a single fault does not stop the dryer.
