The Temprite 320 and 340 Series
are the first
oil separators designed for refrigerant recovery/reclaim systems.
Based on our robust 900 Series, the 320 and
340 Series units are 99.995% efficient in
removing particulates between 0.3 and
0.6 microns (μm) and separating oil from the
mass flow. The elimination of the float ball and
the internal oil reservoir
maximizes efficiency by
minimizing oil carryover.
It also has the advantage
of being one of the
smallest oil separators available for its
capacity. Metering the oil return back to the
compressor may be done by a variety of
methods including capillary tube, a metered
orifice or a timed solenoid. Use the actual
tonnage CFM to correctly size the 320 or
340 Series for your application.

The 500 and 600 Series are
impingement screen-type oil separators.
In these units, the compressed mass flow
enters a larger separator chamber, which
lowers the velocity. The
aerosol oil droplets
collect on the
impingement screen
surface. As the oil
droplets become larger,
they fall to the bottom of
the separator oil
reservoir. The 600 Series
is designed for the OEM
who needs oil separation but does not require
the accessibility of the 500 Series.
The Temprite 900, 920 and 920R Series are
unquestionably the standard in modern oil separation by virtue
of their exceptional performance range. Unlike centrifugal or
impingement screen separators, the 900, 920 and 920R Series
coalescent oil separators are not dependent upon velocity for
efficiency: when the load drops off, the separator keeps working
at 99% efficiency.
The reason why 900, 920 and 920R Series coalescent oil
separators work so well is that they employ a borosilicate
coalescent filter to do the work formerly done by impingement
screens. This exceptionally pure, borosilicate glass filter material
forces the oil aerosol droplets to collide with one another,
collecting into larger droplets until they fall to the bottom of the
separator. Because this filter is finer than a filter/drier, it captures
all solid contaminants and dirt circulating in the system to
0.3 μm. Short, self-contained applications normally have a
small amount of solid contaminants. The Temprite 900 Series is
designed for OEM applications where cleanliness specifications
may be audited.
Temprite developed the 920 and 920R Series
accessible coalescent oil separators for larger
systems with field installations of multiple
connections. These systems tend to be dirtier
and may need to have the filter changed. In
the first 24 to 48 hours of operation, the
coalescent oil separator cleans the system of
all solid contaminants larger than 0.3 μm.
The filter is then changed and a new filter
does the job of separating and balancing
out the system.
If, however, the filter becomes overloaded
with solid contaminants and dirt, it will not
function at optimum performance level. This
problem is solved with the Temprite Pressure Differential
Indicator (PDI). The PDI tells you when the filter is becoming
dirt-logged. Check the pressure differential across the filter and
youʼll know whether or not the filter needs changing. The PDI
may also be wired to an alarm to warn you electronically.
In the event of a compressor burnout, with the 920 and 920R
Series the carbon and solid contaminants are localized at the
separator. You may also install a Temprite 920 Series on a
system that has had a burnout to facilitate clean up. Just put in
a Temprite Clean-Up® Filter to purge the system of unwanted
contaminants. If used in conjunction with a
Standard Filter, you can return the oil to
near-virgin state.
The 900, 920 and 920R Series also
enhance the performance of other
components by eliminating solid
contaminants and oil from the system.
Thermostatic expansion valves work better
because theyʼre dirt free and oil free.
Desiccant in filter driers is more effective
when itʼs not logged with oil, enhancing the
performance of the entire system.
