Condensers
P
arr offers two styles of con-
densers for attachment to
the head of a stirred reactor or
pressure vessel. These can be
made in various sizes to match
the size of the reactor.
Straight Reflux Condenser
The reflux condenser
consists of a length of tubing
connected directly to the head
of a vessel and equipped
with a water cooling jacket.
Condensed vapors are returned
directly to the vessel and
any non-condensable gases
can be released through a
needle valve at the top of the
condenser. A spiral wound
inner packing in the condenser
ensures maximum effective-
ness in a rather short length.
Reflux/Take-Off Condensers
The reflux/take-off con-
denser consists of a water
jacketed tube, the same as
described above, assembled
with a receiving vessel
attached to the lower end of
the condenser. Any vapor, such
as water from a polymerization
reaction, can be condensed and
collected in the receiver, from
which it can be withdrawn
through a bottom valve. Any
non-condensable gases can
be released through a needle
valve at the top of the con-
denser. If condensate collection
is not required, the receiver can
be removed and the condenser
can be mounted directly above
the reactor for direct reflux into
the vessel.
Modifications
Many users opt to install a
ball valve at the head of the reac-
tor below the condenser to use
as a shut-off to the condenser.
Alternate collection vessel vol-
umes are available upon request.
The installation of a con-
denser on any of the Parr
reactors requires a larger port in
the head of the vessel, the size of
which will vary with the volume
of the reactor system. Due to
the limited space on the 4560
mini reactors we would change
either the gage opening or one
of the cooling coil ports to 1/4"
NPT for use with a condenser.
This modification would then
either combine the gage and
condenser functions or eliminate
the internal cooling loop to
accommodate the condenser.
Reactors with volumes of 1 liter
and greater would be modified
with a 3/8" NPT opening or
larger depending on the reactor
volume. The standard head
fittings would be rearranged to
accommodate this port.
