Municipal and industrial sludge dryers exhaust hot, humid, corrosive air. CNCSP corrosion-resistant plate recovery cuts fuel use and supports closed-loop heat-pump drying.
The challenge
Sludge dryer exhaust is laden with moisture, odour and corrosive species. Recovery equipment must survive the atmosphere and avoid cross-contaminating intake air.
How air-to-air heat recovery helps
Use plate sensible cores in 316L or coated construction for exhaust-to-intake recovery, and closed-loop heat-pump drying cores where the process is sealed. No rotary wheels in the corrosive stream.
Recommended CNCSP exchangers
- 316L / coated plate cores - corrosion-proof recovery.
- Closed-loop heat-pump cores - sealed drying circuits.
- No rotary wheels - avoids fouling and carryover.
