Radial scrubber for YBOD

decoweenie · 25th October 2006, 11:03

Just thinking...

Would there be any benefit in a radial scrubber for the Insp ? Looks like more sorb could be used by eliminating the spacer and reducing the length of the bottom springs...
Could the Temp-Stick be usable in a radial scrubber with modifications (i.e. leaning outward within scrubber bed for an in-to-out design) ?
Anyone remember the final verdict concerning which is the better flow path (in-out vs out-in) from the past RBW radial-scrubber debates ?
Anyone made one yet (for the YBOD unit) ?

The SMI artical indicated that in to out was best for heat retention.

I like to see someone make one would be an interesting challenge.

1. The debate rages on about radiel scrubbers but it believed that radial is slightly better.
2. No
3. In to out would be best.
4. Carleton life support use radila scrubbers in their military diving equipmnet.

Thanks. I meant radial scrubber for the YBOD as I am aware there are radial scrubbers for other units.

No. I fear that the distance would be too short to get decent DeltaT.

IIRC, and it was a while ago, but there was a picture of one on BobH's website, which is sadly no more.

I'd be curious to see if the radial would be used up like an axial - in other words, if it would be used up faster nearer one end, because of the shape/airflow.

if it did you'd be ******

and would waste a load of slime

The meg scrubber must over come a similar problem no?

thinking about gas paths would a long radial be better than a long axial ???
thinking gas path length?

IMHO, long radial would have lower WOB than same length of long axial.

AFAIK, axial scrubber would only work well within a certain ratio range of length/diameter. Anything more than ratio of ~2-3 will have very high WOB.

I don't think/know that radial scrubber is restricted the same...

I think coaxial would be a different proposition to an axial. Dunno. Going back to sleep...
