  • Measurement of Freon 14 (CF4) in an Aluminium Production Plant
    Production of aluminium using traditional technology can result in the release of the "greenhouse gas " Freon 14 (CF4). In order to reduce the release of Freon 14 to the atmosphere, improvements must be made to the production process. To see the effectiveness of these improvements, Freon 14 must
  • Ammonia Pressure Measurement using Thermal Flash Protection (.pdf)
    Situation: Ammonia offers refrigeration pump and compressor manufacturers an improved efficiency over Freon based systems. However, the thermodynamic behavior of ammonia is very different from Freon. When the refrigeration pump turns on, the ammonia temperature rapidly changes from 100°F to -70°F
  • Produced Water Monitoring (.pdf)
    Due to the non-availability of Freon, there is need for an alternative method to measure the concentration of hydrocarbons in the effluent today. Current methods use solvent extraction and IR analysis of water samples. In this paper we present an alternative method, which does not use any solvents
  • MICRO: Products In Action
    properties of PFPE coolants do not break down, thus eliminating the need for expensive resistivity monitors and filtration systems that often have been required for other coolants, such as ethylene glycol, glycol/ deionized-water mixtures, and Freon. PFPE fluids are known for being clean and inert and having
  • The Hidden Costs of Compressed Air/Gas Leaks
    , Carbon Dioxide, and Freon systems can be. The focus of this article will be not only how leaks can negatively impact the system as a whole, but also how leaks can affect the environment and quite possibly the well being of the personnel that have to work around them.
  • Enclosure Cooling and Pressurization
    would over time settle on the electronics and cause failures. Switching from filter fans to closed-loop Freon air conditioners protected the manufacturer's panels, however the A/Cs would eventually fail as the mist (and dirt) were drawn into the condenser coil, causing excessive head pressures
  • The refrigerator revolution
    an alternative, less dangerous refrigerant -- enter Freon in the 1930s, which became the standard for many years. Household refrigerators
  • Medical Device Link .
    device requirements such as lubricity and biocompatibility. It all started with a failed experiment on April 6, 1938, at a DuPont laboratory in Deepwater Point, NJ. DuPont scientist Roy J. Plunkett, PhD, was working on developing gaseous Freon-based coolants. As the story goes, when he returned to his
