    "This is a good investment for us, with a high cost-effectiveness. We used to worry about the cow dung in the farm, but now we can use all the dung and flushing water from the pens to ferment and produce biogas for domestic energy. The whole farm is no longer filled with the smell of cow dung, and we can also save a lot of household energy expenses."

    "The gas pump is customized by us according to market demand. It alleviates the problem of insufficient gas pressure and small gas supply during the peak gas consumption period in winter when users use gas boilers for heating, resulting in the inability to heat. Customer feedback is very good."
