Moretec's Examples of Custom Ferrofluid Seals

Multi-axial Feedthroughs
Multi-axial feedthroughs enable the transmission of electrical signals, fluids, or gases through multiple axes, ensuring reliable connectivity in complex systems, often used in aerospace, medical, and industrial applications.
Multi-axial Feedthroughs

Typical Applications that rotary gas unions are used for include:

  • CVD

  • Vacuum deposition systems

  • Gas handling modules

Rotary gas unions
Moretec rotary gas unions provide an effective and adaptable solution for manufacturers of Chemical Vapor Deposition (CVD) and other deposition systems to introduce gases into their processes. The stationary gas inlet connects to the rotating shaft that holds the wafer, ensuring that gas is delivered precisely at the wafer's center. This design enables consistent and uniform coating across the wafer surface.
Rotary gas unions

Typical Applications that rotary gas unions are used for include:

  • CVD

  • Vacuum deposition systems

  • Gas handling modules

Reactive gas seals
Reactive gas seals, commonly used in MOCVD and similar applications, utilize an inert fluorocarbon-based fluid to ensure stability in demanding environments. Their cantilevered seal design effectively shields the bearings from exposure to process gases, enhancing durability. Additionally, the seals incorporate specialized materials, and optional features such as inert gas purges or protective plating can be added to further safeguard components against corrosion.
Reactive gas seals

Typical applications for reactive gas seals include:

  • MOCVD

  • LPCVD

  • PECVD

  • Designs where aggressive cleaning agents are used
