    CHAPTER 2 GENERAL General The Cold Traps KF-24/6B, KF-18/2B, and the Measuring Gas Cooler MGK-1B are suitable for cooling gas to a predetermined dew-point, so that excess humidity condenses. In this capacity the devices can be used in the following applications:...

  • Page 9: Cold Trap Kf-24/6B

    4) Connector for Temperature Controller TR-KF-24 5) Pt 100 The Cold Trap KF-24/6B may be operated indoors as well as in the field. In the field, the user has to ensure that the device is sheltered from the effects of the weather.
  • Page 10 CHAPTER 3 COLD TRAP KF-24/6B The cold trap must stand upright to enable the condensate to drain off freely into the hose connected as condensate collector. Note: The hose must hang free or be arranged so that it can be filled with condensate, without forming air bubbles.
