Yuyun Sanhe is an enterprise specializing in the production of high quality ventilation fans, industrial air heaters, and cooling and humidifying equipment. Our products are designed and manufactured for a wide range of applications as they are primarily used for poultry housing ventilation and cooling, farm heating, workshop climate control, and industrial wood drying. Our biggest advantage comes from the fact that we manufacture all of the components in our equipment independently. This allows us to maintain strict control over product quality. Through years of development, we have been certified by the ISO9001 international quality management system, and we have obtained a number of invention and utility model patents. Details
