Metallic Substrate Technology

Coinverter & filter substrate manufacturing

Herringbone-Formed Metallic Substrate

Features

  • Exhaust gas must pass through a “maze”—increasing contact with the catalyst’s surfaces.
  • Takes higher advantage of the available PGM and oxygen storage components through proprietary herringbone turbulent flow technology.
  • Increased efficiency allows for the potential of platinum group metals (PGM) cost savings and a reduction in catalyst substrate size.
  • More efficient conversion than straight channel designs.
  • Lower cells per square inch (CPSI) over competitive technology improves flow by reducing back pressure for better performance and fuel economy.
  • ACAT’s proprietary bonding technology does not require a flat layer to separate the corrugation layers. This further reduces back pressure as it allows cross channel flow.
  • Metallic substrate can be formed into an endless variety of shapes, sizes and cell densities, enabling smaller or larger volume pieces.
  • Weighs less than equivalent metallic solutions.
  • Metallic substrate has low thermal mass, relative to a comparable ceramic, so that it heats up quickly.
  • Metallic substrate is made with a high-temperature-strength, oxidation-resistant stainless ferrites chromium steel foil with high aluminum content and rare elements that is suitable for a broad range of applications.
