CalRiX

CalRiX

General

CalRiX is a completely synthetic fluid on a fluorine base. It is of low molecular weight, colourless, clear and odourless.

More detailed information about the chemical composition and molecular structure of this fluid can be obtained upon request.

Application

CalRiX can be used with all RITTER Drum-type Gas Meters (Wet-type Gas Meters). Because CalRiX is completely inert to most gases including oxygen, it can be used as a Packing Fluid when water or paraffin oil are not suitable. For example, when the gas needs to remain dry, and when the gas is highly reactive to water or paraffin oil. It is appropriate for use with such gases as:

  • Butane
  • Carbon Dioxide
  • Carbon Tetrachloride
  • Carbon Tetrafluoride
  • Chlorine
  • Deuterium
  • Fluorine
  • Helium
  • Hydrogen chloride
  • Hydrogen Fluoride
  • Methane
  • Nitrogen trichloride
  • Nitrogen trifluoride NF3
  • Oxygen
  • Phosphine
  • Propane
  • Silane
  • Sulphur Hexafluoride

Advantages

  • Extremely resistant even against highly aggressive gases because of CalRiX's fluorine base,
  • less evaporation than water due to its lower vapour pressure, resulting in greater stability of the Packing Fluid level and in more consistent measurement result,
  • very smooth rotation of the measuring drum in the Gas Meter because of CalRiX's high density and low surface tension.
