In sample gas conditioning systems which cannot be pressurised, condensate accumulating in the sample gas coolers must be removed with peristaltic pumps or collected in condensate traps.
The GL 1 and GL 2 traps feature a drain valve and only differ in size.
The GL 3 has a level switch to indicate the fill level or control a pump. The drain is a glass thread version into which a drain valve can optionally be installed.
All condensate traps are made from Duran glass and PTFE, making them corrosion-resistant.
