Why It Matters

Factories exhaust warm air from processes, welding, and general ventilation. Capturing that energy reduces purchased heating and can pre-heat incoming make-up air or process streams.

Typical Energy Savings

Make-up air recovery often cuts heating energy by 40 to 60 percent in heated plants with high exhaust rates.

Recommended Technology

• Plate or heat-pipe exchangers for make-up air
• Run-around coils where exhaust is contaminated

What to Watch

• Dust, fumes, and corrosive exhaust need robust, cleanable cores
• Comply with process and safety codes for the specific industry
