GRETECH hybrid generators powered by LPG will have the same power output with the gasoline, as our mixing valve of our hybrid generators automatically adjusts air intake and LPG/NG to air ratio, allowing the generators to output same power as do gasoline generators. More importantly, when the LPG/NG generators are in use, their engines rotate steadily, allowing stable power output.

GRETECH LPG/NG generators’ expected life expectancy are more than 2 times longer than that of gasoline generators.

Leakage-Proof: GRETECH hybrid generators’ mixing valve is uniquely designed so that even if the gas regulator or switch is kept on, the gas will never leak.

Easy Start: GRETECH hybrid generators, no matter brand new or not being used in a while, can always be immediately turned on by pulling the recoil rope up to 3 times.

Cost-effective: The fuel consumption costs of GRETECH, LPG (0.36 kg/kw.h) and NG (0.35 m³/kw.h) generators are much lower than gasoline generators (0.5 L/kw.h).

Compatible with source pressure ranging from 2.0 to 6.0 kPa (0.29-0.87PSI), our generators are suitable in almost all environments, including at home.

GRETECH generators use perfect amount of LPG/NG to meet output power, so the gas is always burnt completely, producing clean emissions.

The noise of GRETECH generators is 5dB quieter, as own patented muffler.
