Qingdao XLiangMo Agriculture Technology Co., Ltd. is committed to the application of the latest green technology in the modern animal husbandry ventilation environment. It is the pioneer and leader of the flexible fiber positive pressure fresh air system in the domestic yak house, and the standard's promoter. In response to the problem of sending fresh air to the yak house in the winter, the company newly developed FDS system (Fresh air + Fiber Duct System) new fan group + fiber cloth duct system + intelligent system, with uniform air supply, good cooling effect, airflow organization Controllable, controllable terminal speed, etc.it can solve the problem of fresh air in the barn winter, and has a good effect on reducing harmful gases such as ammonia gas and carbon dioxide in cattle, and reducing respiratory diseases of yak house. The intelligent control system can realize unattended operation, and collect parameters such as temperature, carbon dioxide concentration and ammonia concentration through the sensor. If it is within the safe range, the system will automatically stop. Once the parameter exceeds the standard, the system will automatically turn on.
