RainMaker Humidification SystemRainMaker Humidification System

The RainMaker Humidification System (RHS) is the first and only system to generate and deliver precise amounts of ultra pure water vapor purified for both ionic contaminants and dissolved gases.

Needing only filtered house de-ionized (DI) water and power, the RHS adds controlled amounts of pure water vapor directly into any carrier gas stream. It can humidify inert, corrosive, and flammable gases, such as hydrogen and oxygen, at a wide range of flow rates. The system can deliver precise amounts of water vapor into atmospheric processes.

The RHS is an integrated water vapor delivery system featuring adaptive closed loop control. Process parameters are set through automated process recipes or the controller touchscreen. Internal pressure, flow and temperature sensors provide feedback to the control system, which automatically adjusts operations to maintain required temperature and concentration stability.

The RHS consists of a non-porous membrane that excludes particles, micro-droplets, volatile gases, and other opposite charged species from being transferred to the carrier gas and ensures only water vapor is added. The membrane selects only the source gas molecules. Other contaminants in the liquid source cannot permeate across the membrane or enter the carrier gas stream, resulting in a saturated product that is consistent and pure.

Unlike alternative techniques for adding water vapor (bubblers, direct liquid injection, membrane contactors) The RainMaker Humidification System can deliver precise control of water vapor and at the same time remove particles, dissolved gases, and ionic impurities.

Benefits

  • A very low cost solution when compared to vaporizers or Direct Liquid Injection.
  • Low to high flow control range (0.1 slm to 20 slm).
  • Integrated temperature, pressure, and water flow control.
  • Purification of DI water source.
  • Continuous unattended 24/7 operation.
