b. The load overcomes the fact that the water resistance test system cannot accurately control the resistance value, the water is easy to boil, easy to scale, can not be subjected to sudden loading/depression load reduction test, and is difficult to control.It is an upgraded product of water resistance. This product has high safety, low maintenance cost, low noise and strong overload capability.
c. The fan adopts a small axial fan, with large wind volume, good heat dissipation, how noise and other characteristics.
