Gas-to-Air Heat Pipe Heat Exchanger
High-performance air pre-heating from exhaust or flue gas recovery
Industrial exhaust or flue gas streams often contain substantial thermal energy that is lost to the atmosphere. Econotherm’s Gas-to-Air Heat Pipe Heat Exchanger captures this energy and transfers it into an airstream, providing pre-heated air for dryers, furnaces, ovens or other process air-handling systems.
Key benefits and features
High-efficiency heat recovery
Reclaim up to 50-70% (or more, depending on conditions) of sensible heat from exhaust gas, reducing fuel consumption.
Robust heat pipe design
Econotherm's heat pipe architecture avoids common limitations of tubular designs (e.g. thermal stress, leakage) and enables more stable temperature profiles.
Independent element redundancy
Each heat pipe acts independently — localized failure does not compromise the entire unit.
Low maintenance/in-situ servicing
The design allows for pipe replacement or cleaning with minimal shutdown.
Adaptable to fouling environments
Optional cleaning systems (e.g. sonic horns, lances) can help mitigate particulate deposition.
Customizable configurations
Multiple geometries (crossflow, counterflow, parallel flow) and sizes to suit your gas/air flow rates and temperature ranges.
Applications
-
Pre-heating combustion or process air in industrial furnaces or boilers
-
Providing hot air for drying, curing or coating processes
-
Retrofit waste heat recovery on exhaust systems
-
Any scenario where exhaust gas is hotter than required process air
Performance considerations
-
Gas and air flow rates, temperature differentials, pressure drops and fouling load
-
Materials selection to resist corrosion or particulate abrasion
-
Integration with upstream/downstream equipment
