Ecowind is the only Lombardini-branded finished product. It has a double function: it works as an autonomous air conditioner system and as a DC generator able to put in action all on-board devices without even turning on the engine. Powered by a small Lombardini diesel engine, ECOWIND offers the same comfort supplied by vehicle running off. Thanks to these features, it can supply air conditioning, heating and automatic battery charger. ECOWIND isdesigned for all industrial vehicles, from tractors to railway wagons. The air conditioning compressor and the alternator works with a belt drive actioned by the endothermic engine. The auxiliary engine operates the compressor directly without drawing power from the batteries but recharging them! ECOWIND is the only auxiliary power unit on the market able to guarantee the same levels of heating and air-conditioning performance with the vehicle's main engine turned off, as when it is running. It consists in an automotive compressor, an automotive alternator and above all a Lombardini single-cylinder diesel engine.
