Steel Suction Line Accumulators
"U" Tube Style Accumulators
The Parker “U” tube accumulator design is a result of
extensive laboratory testing plus detailed investigation
of the various accumulators currently available. It takes
into account all of the requirements essential for heat
pump applications, including safe holding volume
(relative to the system’s total charge), protected flow
control for positive refrigerant and oil return, and
minimum pressure drop across the accumulator.
Parker offers standard accumulator models designed
for application on heat pump and refrigeration systems
from 1/4 through 12 tons. Liquid refrigerant holding
requirements of suction accumulator may vary by
application. Because of the diversity in heat pump
systems, accumulator capacity selection should be
determined by actual testing. Consult Parker for
assistance if required.
Key Features & Benefits
 Solid copper connections
 “U” tube design for maximum flow of refrigerant and
minimum oil entrapment.
 Inlet flow deflector guides refrigerant toward wall for
smooth tangential flow and gradual expansion.
 “U” tube entrance is positioned behind the inlet flow
deflector to prevent unwanted liquid refrigerant from
entering and damaging compressor.
 Metering orifice matched to system capacity
assures optimum liquid refrigerant and oil flow back
to compressor.
 Protective screen and orifice assembly on "U" tube
protects against foreign particles and contaminants
affecting metering function.
 Fittings and “U” tube are matched to accumulator
holding capacity and total system charge for mini
mum pressure drop and maximum refrigerant flow.
 U.L. listed for 355 psig design pressure.
File No. SA5172.
 Powder paint exterior coating surpasses 500 hour
ASTM salt spray tests.
 Integral 430° F Fuse Plugs (U.L. File No. SA5441).
