District heating substations and energy centres lose heat through ventilation and make-up air. CNCSP plate recovery returns that energy to the network.
The challenge
Substations and plant rooms exhaust warm air while drawing in cold make-up air, wasting recovered heat and stressing the network.
How air-to-air heat recovery helps
Fit plate air-to-air (or brazed or all-welded water-to-air) sensible cores on substation ventilation. Clean, non-critical airstreams allow high-effectiveness recovery with standard aluminium or stainless plates.
Recommended CNCSP exchangers
- Plate air-to-air cores - substation ventilation recovery.
- Brazed / all-welded plates - water-side recovery options.
- High-effectiveness aluminium - for clean airstreams.
Typical configuration
| Parameter | Recommendation |
|---|---|
| Recovery type | Sensible (plate / brazed) |
| Effectiveness | 65 to 85 percent |
| Core material | Aluminium / stainless |
| Arrangement | Substation vent + make-up air |
| Options | Integrated with network controls |
