Greenhouses demand high levels of heat and power throughout the entire year. mtu combined heat and power (CHP) systems provide heat and power simultaneously and are trusted at greenhouses all over the world. The electricity is used to power hundreds and thousands of greenhouse lights needed for growing plants. The heat provided by the CHP system keeps the temperature at a perfect level year-round. For added efficiency, the exhaust gas from the CHP system can be used as a fertilizer.
