Equipment installation and training:

Equipment transportation and installation are all completed by the manufacturer, and the user needs to provide power, air, water, and equipment installation sites. The ground of the installation site must be level. The site area is required to be 20 meters long. The width is 8.5 meters, the height is 5 meters, and an exhaust device is required at the top, and the air volume is 50000m3/h. After the equipment is installed, professional engineers will provide training on operation, safety, maintenance and other matters to the users. Until the user fully grasps the use of the equipment.
