MD3 gas dryer was initially designed to be a part of our stationary Sensonic CGM analyser. Though, thanks to the efficiency, small dimensions, and competitive price, MD3 dryer became interesting alternative and even dedicated solution as a standalone gas conditioner. Its another strong point - universality, makes it available in two different versions: stationary (hung on the wall), and portable for “laboratory” applications.



  • condensation dryer based on the Peltier element
  • built-in peristaltic pump for condensate removal
  • large surface gas filter (optionally two of them) that provides thorough cleaning of the gas sample and long maintenance free intervals

MD3 gas dryer, besides it is supplied as a part of Sensonic CGM gas analyser, can work as an autonomous device Then it is available in two versions:

  1. stationary dryer - MD3 dryer with power supply unit is provided on a common mounting plate. All adjusted to be hung on the wall
  2. portable dryer (for laboratory applications) - dryer is adjusted to set on table and is equipped with uncoupled mains adapter
