With Fibros Thermosyphon system it is possible to supply barrier fluid to double seal arrangement. The pressure of barrier fluid is higher than the pressure of the fluid being sealed. Thus seal faces remain in contact with each other and sealing area temperature is controlled. Thermosyphon system is as per API 682.
Cyclone Separator are designed for removing dirt, sand and solid particles from injection flow to mechanical seal. The separation is obtained by centrifugal force generated by differential pressure across the cyclone.
Fibros Heat Exchangers are incorporated in API Plans 21,23,41 to bring down the temperature of buffer fluid before it enters into seal chamber. Heat Exchanger may be mounted either vertically or horizontally, the vertical mounting being preferred because of better thermosyphon effects.
