There is nothing
standard about Lepido

Founders' Note
In challenging ventilation environments like restaurant kitchens, you need a heavy-duty solution to handle the soot and grease. So, we’ve invented Lepido - the worlds first heavy-duty heat exchanger. A solution that makes energy recovery in impossible environments both possible and profitable.
A number of Lepidos are already up and running in several restaurants, hotels and schools throughout Europe. And, it delivers perfectly. Saving money, energy and CO2 emissions every day.
To convince you, we've done some slightly odd, somewhat scientific and fun demonstrations. Not our standard procedure, but hey, they prove the point. And yes, it was a dirty job, but someone had to do it. Scroll to the end to see the videos!

How it works
Lepido recovers energy from polluted airstreams thanks to our patented Particle Repellent Geometry (PRG®) technology. Watch the video to know more
Why heavy-duty?
Pictures speak louder than words, and these gory real-life pictures of restaurant exhaust ducts are pretty vocal. The grease and soot that are formed when cooking is notoriously hard to deal with and to recover energy from. So, even if there is a standard recovery system in place, it’s normally not working very well, or not at all.

Burger King Malmö, Sweden
Based on data from our test rig at Burger King in Malmö, Sweden, we are able to recover 86.000 kWh per year. See below for how it is set up, and how the air pressure drop is sustained.

"If it sounds too good to be true, it probably is. But, with Lepido, it's the other way around, the systems work much better than expected."

”We have never found a similar product that can recover heat as well as Lepido. It enables energy recovery where it hasn’t been possible before.”
Standard VS Heavy Duty
This is what happens if you use standard equipment in extreme environments...
