Rinse & Cool Flow Diagram
1. Chilled water is circu-
lated through the bucket
to cool the bomb to the
starting temperature.
2. The release valve in the
bottom of the bomb is
opened and the residual
pressure is released
through the bomb ex-
haust line.
3. Once the excess oxygen
is vented, the bomb rinse
water from the rinse
water tank is admitted
through the bomb rinse
solenoid valve and the
check valve at the top
of the bomb. The bomb
rinse water is released to
the wash bottle.
Note: Several rinse
patterns may be con-
figured by the user to
meet various opera-
tional and analytical
requirements.
4. The bomb is filled one
more time with oxygen
to help flush
the water
residue
from the
interior of
the bomb.
