[labnetwork] H2 Generators

[Grimard, Dennis]

All:

I have been watching the discussion regarding H2 generators.  Although I agree with most of what has been said I worry about being able to shut off the generator in case of a leak.  The generator does not know that it is delivering into a leak and unless the leak is detected then the generator will continue pumping to that leak.  Adding detectors is not the solution.  H2 detectors are difficult to place such that they will pick up a leak.  Do you add detectors at every possible leak point?  Add in the high velocities of the cleanroom and I hesitate to change from bottles to generators.

When considering the costs, you also have to consider the cost of the added detectors ... which are not cheap ...
