Air-to-air heat recovery pays off wherever a building or process exhausts conditioned air. Below is a survey of the industries we see most, with the recovery type that fits.
| Industry | Key driver | Recommended type |
|---|---|---|
| Data centers | Massive, constant exhaust; free cooling | Plate / heat pipe (air-side, free cooling) |
| Commercial HVAC | Ventilation energy, code compliance | ERV/HRV plate or wheel |
| Industrial drying (food, pharma, herbal) | Recover latent + sensible from wet exhaust | Rotary wheel, run-around coil |
| Cleanrooms | High airflow, strict isolation | Plate (no cross-contamination) |
| Mine / tunnel | Ventilation heating in cold climates | Plate with defrost |
| Livestock | Reduce heating, keep humidity down | HRV plate |
| Marine / corrosive | Salt, vibration | 316L / titanium plate |
| Ceramic & cement kilns | Very high exhaust temperature | Recuperators, run-around |
| Lithium battery (NMP recovery) | Solvent + energy recovery | Run-around coil + condenser |
Why the pattern repeats
In almost every case the exhaust carries energy you already paid for. Recovering it shrinks the heating/cooling plant, lowers peak demand, and often unlocks compliance with efficiency codes (see our standards section).
