  • SF Maintenance Equipment Fundamentals

    As a hybrid of the high-pressure and refrigeration process, heat-exchanged systems rely on a series of forced-air coolers to extract heat from the compressed SF 6. As a benefit of reduced temperatures and pressures, this approach allows gas to be liquefied at a slightly faster rate than the direct high-pressure approach.
