The Model GD402 gas density analyzer and Model GD40 detector not only provide continuous measurement of gas density, but also several other valuable parameters, including specific gravity and molecular weight.
The GD40 detector is designed for intrinsically safe and flameproof, explosion protected applications. It is designed to be virtually maintenance free for all accepted applications.
- Low Installation Cost
- Virtually Maintenance Free
- Not affected by Dust or Oil Mist
As the sample reaches the second stage, it is directed through a transition piece which channels the air evenly across two active cooling elements. The cooling elements provide 360 degree contact between sample and coolant.
As the cooling takes place, condensate and Heavy Hydrocarbons removed from the sample are gravity fed back through the reflux section, washing the sample inlet of particulate and other fouling compounds.
Temperature is tightly controlled with a single point temperature measurement fed to a controller which cycles the two active cooling elements.
