Eco-Efficient Innovation

With YANMAR systems, efficiency comes naturally. That's because our innovations are driven by a desire to create more eco-efficient, life-sustaining technology. This is demonstrated across many of our solutions:

micro CHP Systems: Distributed generation micro CHP systems are able to generate the right amount of power at the right time, making them much more efficient than the electrical grid. YANMAR micro CHP units also produce less carbon dioxide, nitric oxide and nitrogen dioxide emissions than typical grid power generation plants.

Heat Pump Systems: Switching from electric driven heat pumps to YANMAR's high efficiency gas driven heat pumps reduces electrical load by approximately 90%. These units effectively lower peak demand for electrical power during the summer air conditioning season.

Power Generation Systems: YANMAR's power generation systems maintain the supply of electricity during grid power failures, ensuring that emergency equipment, mission critical systems and hardware continue to operate.

Drive Systems: YANMAR Pump Drive Systems are used in storage and drainage pump facilities, as well as irrigation applications in large and small scale waterworks systems.

Photovoltaic Systems: YANMAR works collaboratively to integrate highly efficient micro CHP (cogeneration), gas heat pump and emergency power generation products combined together with solar products to provide higher efficiency total energy systems.

Remote Monitoring Systems: YANMAR enhances the precision and reliability of maintenance support services through the integration of YANMAR's Remote Monitoring System and certified dealer network.
