Waste no energy
Lepido is a heavy-duty heat exchanger for restaurant ventilation. It is built to withstand grease and soot without the use of filtering techniques.

With Lepido...
…energy in the exhaust air of the ventilation system is recovered and returned to the building for multiple usages in its operations, thus reducing both the energy cost and the emissions of fossil CO2.

Without Lepido...
…a traditional system can’t recycle energy from the restaurant exhaust air. Because of this tremendous waste, the average restaurant vents as much as 85.000 kWh every year.

The flexible energy outputs gives Lepido a distinct advantage over traditional systems and gives our customers further opportunities for monetary savings.


Lepido is based on two unique patents
While other technologies try in vain to use filters to eliminate the impurities in the exhaust air, the Lepido system utilizes its stalwart recovery battery, managing to recycle energy in this challenging environment. Enjay’s patents, PRG and APC, keep the coils of the recovery battery effective over time and minimize the necessary maintenance.

Restaurants
The Lepido system recovers energy from restaurant ventilation system in all types of buildings, such as fast-food restaurants, hotels, food courts, shopping malls, schools, hospitals etc. The recovered energy can be used for heating and cooling in the ventilation, pre-heated tap water, under floor heating and even heating or cooling of swimming pools. As an added benefit, Lepido can – at the same time as delivering recovered heating - also provide cooling as a boost to any water-based cooling system, when the energy system in the building requires it.
The recovered energy decreases the need to purchase electricity, gas or district heating. The increased energy efficiency of the building lowers the running costs for the property owner and reduces emissions of fossil C02.

Marine
The Lepido system recovers energy from galley ventilation in marine vessels such as cruise ships, ferries, ro-pax, accommodation platforms, and any other vessel with larger crews. The recovered energy can be used for heating in HVAC, pre-heating of water to a calorifier and heating of swimming pools. As an added benefit, Lepido can – besides delivering recovered heating - also provide additional cooling as a boost to any water-based cooling system, when the energy system requires it.
The recovered energy decreases the need to generate electricity produced by AUX engines onboard the ship. The increased energy efficiency of the vessel results in lowered fuel consumption which equals reduced emissions of fossil CO2 and running costs.

Food processing
The Lepido system recovers energy from the ventilation in all types of food processing facilities, such as production of snacks, ready meals and semi-finished food products.
The recovered energy can be used for heating in the ventilation and to pre-heat tap water / process water. As an added benefit, Lepido can – besides delivering recovered heating - also provide additional cooling as a boost to any water-based cooling system, when the energy system in the building requires it.
The recovered energy decreases the need to purchase electricity, gas or district heating. The increased energy efficiency of the building lowers the running costs for the property owner and reduces emissions of fossil C02.
