Vaporization Products

Many industrial and semiconductor processes need to convert liquids including both water and other liquid precursors into highly controlled and pure vapors. Vaporization is a phase transition from the liquid phase to gas phase.

A vaporizer therefore, is any system that converts a liquid material to a gaseous state. While vaporization is achieved in a number of different ways, all modern vaporizers – such as water vaporizers – have several common characteristics::

  • Increase temperature and/or reduce ambient pressure of the liquid
  • Enclosed systems to capture and control vapor flow
  • Utilize feedback & control loop system to regulate vaporization rate

Key Applications

  • Water vaporization/humidification
  • Chemical vapor deposition
  • Depositing thin films for enhanced thermal, optical or hardness characteristics
  • Vaporizing monomers for vacuum polymer film disposition
  • Generating calibration vapor
  • Vaporizing liquid hydrocarbons

Semiconductor Products

Precise and repeatable process control: It is the fundamental driving factor when manufacturing electronics and semiconductor products.
