Grease-Laden Air
Heat Exchanger
Challenge belief that heat recovery fails
in dirty-air systems
Why Traditional Heat Recovery Systems Fail
Blocked. Broken. Binned.
Most heat recovery systems weren’t built for the real world — they struggle with environments full of grease, lint, soot, or particulate matter. These contaminants build up quickly, leading to:
Clogged heat exchangers
Rapid efficiency loss
Frequent maintenance or total failure
In kitchens, laundries, or food production, these systems rarely survive their promised lifespan. They’re designed for clean air, not the air you actually have.
Here’s why ours doesn’t.
Enter Lepido: Particle Repellent Geometry
recovers heat with up to 68% efficiency, even from heavily polluted airstreamsHow It Works:
Wider Coil Spacing Our coils are spaced farther apart than the tightly packed fins of conventional systems. This allows dirty air — full of particles — to pass through rather than get trapped.
Unique Airflow Pattern The airflow is designed to repel particles from the coil surface, reducing fouling and pressure drop, even if coatings begin to form.
Efficient Heat Transfer, Always Despite the open geometry, Lepido has the same heat transfer surface area as traditional exchangers — thanks to a larger footprint and smart counter-current flow with multiple fluid paths.
Waste heat, recovered. Even in the dirtiest exhaust.
Enjay® is the world’s first heat exchanger designed specifically for polluted kitchen air. No filters. No clogging. Just clean, profitable energy savings from air that would otherwise be lost.
