Lepido©

Heavy Duty heat exchanger - developed specifically for polluted airstreams.

How it works

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.

Enjay_howitworks02-1

Without Lepido...

...the air from the kitchen is too polluted for traditional heat exchangers as they clog up from grease and soot build up. So instead, the kitchen air is vented straight out with no energy recovered at all.

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.

Brine connections
Counterflow configured brine connections enables energy transfer from the air stream to the heat pump.
Flange
Universal fitting. Bolted joint or clinch slide guide joined.
PRG
Particle Repellent Geometry. The aerodynamic configuration of the coils allows the majority of the particles to pass straight through the battery, without getting stuck to the coils.
Housing
Follows the most stringent fire protection regulations. All stainless steel, durable as the house it’s situated in. The housing is simply a part of the grease duct; Installation made easy.
Drainage
Drains continuous condensation as well as the minuscule amount of grease released by the APC. The grease drains down to the restaurant’s grease trap.
    • Example: Fast Food Restaurant

    Particle Repellent Technology

    Lepido recovers energy from polluted airstreams with up to 65% efficiency thanks to our patented Particle Repellent Technology (PRG®)

    How PRG works

    Lepido, being a heavy-duty heat exchanger, is larger compared to a traditional heat exchanger to make room for our patented geometry of the recovery coils. The space between the coils is much larger than between fins of a traditional heat exchanger.

    The result is a unique airflow pattern where most of the particles can pass through the heat exchanger instead of sticking to the coils. This slows down the build-up on the coils and makes the air pressure drop minimal, even if a coating has formed.

    Lepido, being coil-based with one hundred percent counter-current and multiple fluid patterns, has the same heat transmission element surface area as a traditional heat exchanger.

    Particle Repellent Geometry

    The aerodynamic configuration of the recovery coil causes the majority of the particles of grease and soot to pass through the unit without getting stuck to the coils.
    Area of operation
    enjay_ourvision_area_restaurant

    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.
