A knitwear plant exhausts 50,000 m3/h of stenter air at about 110 C with fibre and lint. EN159 recovered sensible heat with a plate exchanger to avoid fouling.
The Challenge
Knit stentering exhaust carried lint that would foul a rotary wheel. The plant wanted high effectiveness without rotating-part maintenance.
Why Plate Air-to-Air Recovery
For fibre-laden stenter exhaust, a plate exchanger avoids the fouling and leakage risk of a rotary wheel. Sensible recovery with separated streams is robust and easy to clean.
The EN159 Solution
EN159 BXB welded stainless plate module, 50,000 m3/h, intake 20 C raised to 70 C, lint prefilter upstream, blow-down cleanable.
Measured Results
- Recovered heat: about 1.0 MW
- Intake preheated from 20 C to 70 C
- Fuel use cut by 24 percent
- Estimated payback: 16 months
Compliance and Selection Notes
Plate sensible recovery chosen for lint-laden exhaust. Rotary wheel avoided due to fouling risk on this line.
Frequently Asked Questions
Why plate instead of wheel here?
Lint would foul a wheel; the plate is lint-resistant and cleanable.
Can it take 110 C exhaust?
Yes, welded stainless plates handle this range.
