Cleanrooms and laboratories exhaust large volumes of conditioned air. Recovering that energy with air-to-air exchangers cuts HVAC load — but GMP, ISO and contamination rules mean recovery must be sensible-only, with no exhaust-to-supply cross-flow. This hub collects CNCSP application notes on cleanroom, pharma, food-process and fab exhaust recovery.
Cleanroom & lab exhaust recovery
- Cleanroom / laboratory exhaust energy recovery
Plate and rotary options for ISO-class cleanrooms, with leakage-class and pressure-balance considerations. - Pharmaceutical exhaust heat recovery (no recirculation)
GMP rule: recover sensible heat but never recirculate exhaust air. Design boundaries explained. - Food & pharma process exhaust recovery
Process-exhaust recovery routes and the hygiene constraints that shape them. - Semiconductor fab exhaust recovery
Fab exhaust is corrosive and highly variable; sensible-only recovery and material selection.
