What do corrugated ceramic fillers 350Y and 400Y mean?
Thread Content
Ceramic structured corrugated packing. There are many filler units with the same geometric shape - corrugated sheets stacked parallel to each other. The main models include 100Y, 125Y, 160Y, 250Y, 350Y, 450Y, 550Y, and 650Y. The number represents the theoretical number of blocks, unit block/meter, for example, 350Y represents 3.5 to 4 blocks per meter.
Some are also expressed as: 350 is the specific surface area 350m2/m3, Y refers to the tilt angle 45°
The 350 in 350Y represents the corrugation specific surface area of 350㎡/m³, and Y represents the corrugation inclination angle of 45 degrees. The 450 in 400Y represents the specific surface area of the corrugation is 400㎡/m³.
