Why It Matters

Industrial laundries use steam and hot water and vent hot, moist air. That exhaust holds substantial recoverable heat.

Typical Energy Savings

Recovering heat from dryer exhaust and pre-heating water can cut total energy use by 20 to 35 percent.

Recommended Technology

• Air-to-air plate exchangers on dryer exhaust
• Air-to-water exchangers to pre-heat wash water

What to Watch

• Lint and moisture require frequent, easy cleaning
• Condensate drainage must be managed
