Metal Super Mini Ring – Superior to Cascade Mini Ring

Metal super mini ring, an advanced random packing type, has similar structure with metal casecade mini ring, which has rectangular openings, conical edge and reduced height. But the metal super mini ring doesn't have the curved blade. It can improve the strength of packing through adjusting the arc of continuously bending curved rib. Super mini ring can ensure orderly place and fluent flowing channel. besides, this design supplies low pressure drop and better treating capacity and mass transfer performance. Additional, because of the regular structure, it can ensure the uniform outward to increase the bulk density for better filtering and separating performance.

MSMR-01: Metal super mini ring features large voidage and excellent mass transfer performance.

Two metal super mini rings: one is placed flat and the other is raised vertical.

MSMR-02: Metal super mini ring has flat edge not bevel edge as cascade mini ring.

Two different sizes of metal super mini rings with internal curved rib.

MSMR-03: Internal curved rib replaced the internal fingers of cascade mini ring.

Specification

Material: carbon steel, stainless steel and aluminum alloy steel.
