Rotary Heat Exchanger (Energy Recovery Wheel)
CNDOI rotary heat exchangers (energy recovery wheels) deliver the highest air-to-air recovery rates for large air handling units and industrial ventilation. A purge sector minimizes supply/exhaust carryover, and both sensible and enthalpy (desiccant) media are available.
Key Features
- Sensible efficiency 75-85%; enthalpy 60-80%
- Purge sector to reduce carryover (typically <1%)
- Aluminum or molecular-sieve/desiccant coating media
- Diameter 500-4000 mm, variable speed drive
- Summer/winter bypass for free cooling
Typical Parameters
| Model | Diameter (mm) | Airflow (m3/h) | Eff. | Media |
|---|---|---|---|---|
| RW-1500 | 1500 | 8000 | 80% | Sensible AL |
| RW-2500 | 2500 | 22000 | 82% | Enthalpy |
| RW-3200 | 3200 | 40000 | 85% | Enthalpy |
Applications
- Large AHU and central HVAC plants
- District heating / cooling ventilation
- Industrial process exhaust recovery
- Airports, metro and large public buildings
