 High efficient metal filling |
Step Ring absorbs advantages of short Raschig ring and improves PALL ring. Height diameter ratio of the ring is 1:2 and taper rolled edge is added to one end. It reduces resistance when the gas goes through the machine bed and increases flow rate. The intensity of the filling is quite high. Due to its structural characteristics, gas and liquid are distributed evenly and contact area of gas and liquid is increased, thus improving mass transfer efficiency.
