- A metal-finishing plant exhausted 18,000 m3/h of 160C air from curing ovens to atmosphere - pure lost energy. The brief was to recover it for winter make-up air heating and preheat a process water loop.
- A high-temperature plate air-to-air exchanger (stainless, rated to 200C+) transferred exhaust heat to incoming fresh air. A secondary air-to-water coil pulled surplus heat into the water buffer. Fouling-prone exhaust demanded a cleanable core and a maintenance plan from our cleaning guide.
- Recovered ~520 kWth at peak. Gas boiler load cut ~35% in winter. Payback: 2.8 years.
- Capture heat in grade order - high-grade first (process water), low-grade last (ventilation). Match the core material to exhaust temperature and contaminants. See waste-heat recovery basics and the standards overview before specifying.
