Rotary Heat Exchanger vs. Plate vs. Heat Pipe: Selection Comparison and Application Scenarios

Three forms are commonly used for industrial exhaust-air energy recovery, each suited to different operating conditions:

Type	Heat Recovery Efficiency	Advantages	Limitations	Typical Scenarios
Rotary	Sensible 70–85% / Total 60–75%	Recovers both sensible + latent heat; continuous for large airflow	Slight cross-contamination (mitigated by double sealing)	Fresh-air HVAC, drying, coating
Plate	Sensible 60–80%	No moving parts, no cross-contamination	Sensible heat only; prone to condensation and clogging	Cleanrooms, cross-contamination-sensitive occasions
Heat pipe	Sensible 50–70%	Remote heat transfer, no power required	Sensible heat only, lower efficiency	Small airflow, separated spaces

Hard-and-Fast Selection Rules

• Need simultaneous humidity control (latent-heat recovery) → choose a rotary heat exchanger.
• Clean/sterile, zero cross-contamination → choose plate type (sensible heat).
• Large-airflow fresh-air pre-cooling/pre-heating → rotary offers the best cost-performance.
• Low-dew-point drying (dew point < -10°C) → rotary dehumidifier.
