Lepido by Enjay is a heavy-duty heat exchanger for restaurant ventilation. It makes it not only possible, but also profitable, to recover energy that is currently being wasted.
Lepido, being a heavy-duty heat exchanger, is larger compared to a traditional heat exchanger to make room for a patented geometry of stacked recovery coils. The heat transmission element has the same surface area as a traditional heat exchanger but the space between the coils is much larger than between the fins of a traditional heat exchanger. This results in a unique airflow pattern where heat can be recovered while most of the particles can pass through the heat exchanger instead of sticking to the coils. This also slows down the build-up on the coils and keeps the increased air pressure drop to a minimum, even if some coating has formed.
A restaurant can save an average of 85.000 kwh every year by installing a Lepido and re-calculated with fossil CO2/kWh equivalents* contribute with an average decrease of 34 metric tons of fossil CO2 emission per year. If every restaurant in the world used Lepido, fossil CO2 emissions could decrease by 500 million metric tons per year.
So yes, size matters.
