Ettes Power Solutions
The energy supply equipment not only provides electricity, but also heat too. This is named CHP. The heat provided can be used for hot water, heating facilities and steam. Additionally, it can also be used to generate cold. The combined utilization of heat and power can increase the comprehensive efficiency to more than 90% in the process of power generation. It can save as much as 40% of the primary energy and reduce carbon dioxide emissions by 60%. This is the reason why CHP is highly efficient and environmentally friendly.
► Environmentally friendly
► Energy saving
CHP solves the problem of waste disposal and protects the environment. Electricity produced meets the local demand and public grid. Heat produced is recovered to optimize the living condition.
About 100-200m3 landfill gas with the heat value of 3.5-5.5kWh/m3 is produced per 1 ton landfill. It is a high-quality fuel used on the CHP units, and so this saves energy and protects the environment.

► Cylinder temperature protection system
Cylinder temperature sensors or exhaust manifold temperature sensors can measure the combustion or exhaust gas temperature and send signals to the control system to monitor engine's operation condition and ensure normal operation.
► Detonation control system
Based on the signals from sensors, the controller sends out analog signals to ignition system after processing so as to adjust ignition timing, reduce load or shutdown to avoid detonation.
► Gas leakage protection device
This avoids gas leakage and once the gas leaks, gas pipeline will
be turned off and alarms will be sent out.

The shutters control inlet and outlet automatically, i.e. close shutters when CHP unit stops or open them when CHP unit starts,
thus these achieve automatic adjustment and prevent small
animals entering into the unit when it stops. Once gas leakage
happens, they are closed automatically to isolate internal air
and prevent explosion.
