Why It Matters

Food plants use heat for pasteurisation, drying, and cleaning, then vent warm, often humid air. Capturing that energy lowers both utility cost and carbon.

Typical Energy Savings

Exhaust-air recovery paired with a heat pump can cut process heating demand by 30 to 50 percent in suitable lines.

Recommended Technology

• Plate exchangers for make-up air pre-treatment
• Run-around coils or heat pipes where airstreams must stay separate

What to Watch

• Use hygienic, cleanable surfaces and food-grade materials
• Manage condensate and grease in exhaust streams
