Heat Pipe Heat Exchanger
CNDOI heat pipe heat exchangers use a passive, gravity-driven two-phase loop with no moving parts and, critically, no cross-contamination between airstreams. They are the preferred choice wherever exhaust must never mix with supply air (kitchen, mine, pharmaceutical, corrosive environments).
Key Features
- Passive operation, no fan or power required
- Complete airstream separation (hygienic)
- Efficiency 50-70% sensible
- Works in vertical or inclined orientation
- Resistant to fouling; easy maintenance
Typical Parameters
| Model | Airflow (m3/h) | Eff. | Working fluid | Application |
|---|---|---|---|---|
| HP-1000 | 1000 | 60% | Refrigerant | Kitchen exhaust |
| HP-3000 | 3000 | 65% | Refrigerant | Mine ventilation |
| HP-5000 | 5000 | 70% | Refrigerant | Industrial process |
Applications
- Mine and tunnel ventilation heat recovery
- Commercial kitchen exhaust air pre-heating
- Pharmaceutical / clean process (no mix)
- Corrosive or dusty industrial exhaust
