Industrial drying is one of the largest consumers of process heat in manufacturing, food, agriculture, wood processing, and wastewater treatment. Across all of these, vast amounts of energy leave the plant as hot, humid exhaust. This cluster examines how air-to-air heat recovery - fixed-plate exchangers and rotary enthalpy wheels - captures that energy and returns it to the drying process.

Each application page below breaks down the right exchanger type, the sensible-versus-latent trade-off, and the operating rules that protect both product quality and equipment. Whether you run a low-temperature food dehydrator or a high-heat industrial oven, the pattern is the same: stop venting the heat you paid for.

What this cluster covers

• Exhaust heat recovery fundamentals - sensible vs latent heat and where the savings come from.
• Plate vs enthalpy wheel - when to recover temperature only and when to recover moisture too.
• Frost, fouling and corrosion control - the operating rules that keep dryers running.
• Energy savings and payback - typical heater-energy reductions and simple payback periods.
