Tri-Packs® is a sphere-shaped column packing with intricate group of ribs and struts. It was introduced in 1980's and is since recognized by its geometrical shape. Its spherical shape offers good surface area to void space ratio. There is virtually no nesting or settling since there are no obtruding edges. Due to circular and consistent design of each packing, high mass transfer rates are achieved. | |

MACH Mini Rings (MMR) have cylindrical surface and linear internal braces, which provides low height to diameter or aspect ratio compared to standard cylindrical ring type packing. The low aspect ratio design ensures even liquid flow, which leads to substantially better gas and liquid contact. Its shape allows higher bed heights with little deformation and low-pressure drop across the bed. MMR was developed and commercialized in 1971. Since its introduction, MMR random packing has been utilized in a wide variety of distillation, absorption and stripping columns around the world. The superior performance of MMR random packing has been shown in thousands of successful installations by MACH Engineering, LLC. | |

Maspac was initially developed by Dow Chemical Company after a long period of testing. This high performance packing was designed specifically for handling very high liquid and gas flows with low pressure drop. Maspac is most often specified because of its shape and physical properties. Its overall shape provides high flooding limits and low pressure drop to high liquid and gas flow, enabling minimum blower requirements. The shape has an extra large surface area confined in a small space to provide high gas-liquid contact efficiency. | |

MACH CORRUGATED Structured Packing is the one of the most economical structured packing in the industry. It is ideal for separations requiring a large number of theoretical stages in low liquid rate absorption/stripping systems, also for applications that require a wide operating range. This is due to very low pressure drop across the bed and superior liquid spreading characteristics over the packing surface. Specially designed vertical sheets maximize gas/liquid contacting, mixing and renewable liquid film formation. These sheets include pressure drop reducing and liquid diversion openings that are strategically located where they are needed resulting in a higher capacity with no dead space. The shapes of the openings are specially designed for guiding and directing gas and liquid flows for full integration of gas/liquid contacting. The unique design of these openings provides maximum area and distribution. In a typical application, the fluid flowing down the column drips off the downward facing tabs and spreads on the surface of the sheets. In high liquid loading applications where the liquid might have a tendency to bridge the opening, an upward bent tab directs the liquid to the underside of the corresponding sheet. Some of the benefits are: - Increased capacity & Low pressure drop
- Resistance to plugging and foaming
- Higher strength for same thickness material
- Wide turn down and low HETP
- Ease of installation and maintenance

MACH Knitted Wire Structured Packing (KWSP) is the Goodloe® equivalent. KWSP is based on metal or polymer fabric which is knitted instead of woven. Knitting is a more economical process, with results which are superior in many respects. The packing is made from four to twelve strands, each typically 0.0045 inch diameter with appropriate loop spacing and corrugation depth. Tubular knitting, followed by flattening and corrugation, yields a flexible ribbon about six inches wide with two integral layers. This results in high-efficiency structured packing which is ideally suited for applications that demand high separation efficiency with a lower pressure drop. Its low HETP requirements result in smaller column heights. The multiple strand wire provides a high surface area and a tube effect on the downward liquid to promote close vapor-liquid contact, uniform liquid distribution and a thin layer of liquid film. This results in higher mass transfer efficiencies, lower pressure drop, and high turndown ratios, up to 20:1. Typical HETP values range from 3" to 12". For high vacuum services, 4" to 6" HETP is typical. Some of the benefits are: - Lower packing height due to high efficiency
- Higher operating range due to low pressure drop
- Easy installation and removal
- Wide range of material

VSP®, also known as Arch Ring, has arch slotted from one sheet of metal. Its spherical shape offers good surface area to void space ratio. The sizes of Arch Ring are proportional in all dimensions for accurate scale-up. Heavily ribbed main element provides high strength-to-weight ratio sufficient for high bed heights. This type of design helps the liquid to form tiny droplets as it trickle down the packing, assuring good liquid-gas mixing and distribution. Its shape allows virtually no nesting and large void space produces low-pressure drop across the bed. | |
