タイトルまたは説明

We invented positive displacement condensing gas-fired heat-exchanger device which was in ahead at international level. This technique supplies a gap in domestic gas burning and heat exchange technique and applied national patent. Products with this technique not only have extremely high heat exchange efficiency, but the end gas also approaches to zero emission. Therefore, this product has been cognized as First Grade energy efficient product by CGAC, and received related cognition and logo licensing files.
Heat exchange enables the thermal efficiency to reach over **0%.
