Industry Problem
Textile stenter (tenter) frames exhaust very hot, humid air (120–180°C) continuously. That heat is the largest energy loss in finishing and the easiest to recover.
Exhaust Conditions
Stenter exhaust is high-temperature, moisture-heavy and carries fibre/lubricant aerosol. Make-up air must be heated for the chamber.
Recovery Principle & Recommended Exchanger
Use a stainless-steel plate exchanger or a run-around coil; both keep streams separate and resist the humid, slightly corrosive load. Full-stainless stenter retrofit preheats make-up air. For combined flue + stenter loads, see boiler flue-gas + textile recovery.
System Configuration
- Plate core recovers sensible + some latent heat to make-up air.
- Stainless, cleanable plates; condensate drainage.
- Run-around where the exhaust stack and air intake are distant.
Energy-Saving Potential
Recovering 30–50% of stenter exhaust heat typically cuts finishing fuel 20–40%.
Material & Design Considerations
304/316 stainless; high-temperature seals; fouling access for cleaning.

FAQ
What temperature can a stenter plate core take?
Stainless plate cores handle 120–180°C exhaust routinely; size the approach temperature for the make-up-air preheat you need.
