Component Descriptions

ecopower® Our microCHP system. The ecopower® produces both heat and electricity. The ecopower® is a grid connected device. It is designed to complement and replace grid power, as well as provide heat, and not function as a back-up power supply. Select the Cogeneration Tab for detailed information on the ecopower®.

Parallel Operation The ecopower® can be configured with multiple units linked in a single installation, increasing the electrical and heat output. For instance, two units running in parallel mode provide up to 9.4 kW of electrical power at 230 VAC and up to 25 kW (85,000 BTU / hour) heat. Parallel Operation is currently available and shipping.

Buffer Tank A hot water storage device that is the interface between the ecopower® and the heating system in the building. The temperature in the Buffer Tank is controlled by ecopower® based on programmed conditions set by the owner. This tank is purchased separately and sized for the application and can be one tank or multiple tanks, depending upon need.

Pump Package This is a pump and mixing valve that is included with the ecopower®. These components are critical to the operation of the system as they control the flow of cooling water to the heat exchanger in ecopower® and modulate the engine temperature.

Radiator This device is an option for an ecopower® system configuration. The radiator expels heat from the buffer tank if the set temperature is exceeded. NOTE: This typically occurs if the ecopower® generated heat cannot be expelled in the residence.

Transformer An isolation transformer used as a safety device to isolate the ecopower® from direct contact to the grid. This is included in the purchase price of the ecopower®.
