Metal Saddle Packing/Metal Saddle Rings (IMTP®)

Metal saddle rings are a type of random tower packing suitable for high-capacity and high-performance applications.

MACH metal saddle rings offer excellent performance at an accessible price point along with guaranteed material quality. We have a wide range of metal saddle ring packing options in various sizes and configurations, including stainless steel saddles. We can also design a custom product for specialized applications. Our metal saddle rings are comparable to IMTP® and RMSR®.

Our metal saddle rings combine the high void fraction and the well-distributed surface area of the pall ring with the low aerodynamic drag of the saddle shape. Additionally, when compared to the pall ring, our metal saddle rings Compared to the Pall Ring, provide a more open shape and improved liquid spread.

Metal Saddles

Metal Saddles Product Overview

The first metal saddle ring was designed in the 1970s. MACH Engineering’s product takes this basic design and updates it to deliver improved performance and long-term value. While comparable to IMTP®, our product has a unique external geometry with a variety of fingers, arches and other features that prevent entangling and provide a large surface area to promote gas/liquid contact.

Key Benefits of Metal Saddle Rings

Metal saddle rings offer several benefits over other tower packing products, including:

  • Lower pressure drop: Metal saddle packing provides lower pressure drops, which in turn reduces foaming and energy consumption.
  • Higher efficiency: By providing higher efficiency over a wide flow range, metal saddle rings deliver enhanced performance that permits smaller column diameters for designing new systems.
  • Better mechanical strength: A variety of material options lets you configure your purchase for optimal strength-to-weight ratio — select products are suitable for use in packed beds up to 50 feet deep.
  • Minimal drag and hold-up: Random geometries and an improved surface area promote improved interfacial gas-liquid contact with minimal hold-up.
  • High operation elasticity: Metal saddle ring tower packing offers a flexible solution that can adapt to operational changes while maintaining superior quality and performance.
  • Large flux: Besides enhancing liquid distribution, nutter ring tower packing can significantly improve the flux of the gas by making it larger.
  • Superior surface utilization: Metal saddle ring packing provides increased surface utilization for enhanced process results.

Materials and Sizes of Metal Saddle Packing

MACH Engineering designs metal saddle rings from the following materials:

  • 304 stainless steel (304 SS): This most common stainless steel version offers excellent resistance to numerous atmospheric environments and corrosive media.
  • 304L stainless steel (304L SS): This stainless steel type offers a slight but noticeable performance reduction over standard 304 alloys, but its lower carbon content minimizes potentially harmful carbide precipitation.
  • 316 stainless steel (316 SS): This marine-grade stainless steel product offers excellent corrosion resistance and protects against elevated temperatures and acidic elements.
  • 316L stainless steel (316L SS): This stainless steel option offers a lower carbon content than its 316 counterpart — its carbon content cannot exceed 0.03%.
  • Carbon steel: This special steel type offers a higher carbon concentration, making it stronger and less likely to break under pressure.
  • Aluminum: This lightweight metal offers excellent corrosion resistance and conducts heat and electricity well.
  • Copper: As an industrial metal, copper is highly ductile and malleable. It also offers strong electrical and thermal conductivity and reliable corrosion resistance.

316 stainless steel has better corrosion resistance than 304. 304L and 316L are low-carbon stainless steel variants. We can make your stainless steel saddle rings in the preferred material.

We offer our products in 1-, 1.5-, 2- and 3-inch sizes, which have a void fraction between 97 and 99 percent and geometric surface areas ranging from 68 to 18 ft2/ft3.
