Additional information was sent to me on 20 September 2006 by J.
Voets (NL) stating following:
I have some additions to the Ray data:
The 50% dosage nozzle is part of the standard delivery.
32%, 40%, and 100% dosage nozzles are available too.
The 40% nozzle has a flow of approx. 12 /tr/min.
The guaranteed scrubbertime of 70 minutes are on the safe side.
Scrubber time of 100 - 110 minutes seem to be possible (NOT
VERIFIED!)
Unit is delivered with a 5 ltr bottle.
Thanks Mr. Voets. |
