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 mini-
mum 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 appli-
cation. Because of the diversity in heat pump systems,
accumulator capacity selection should be determined
by actual testing. Consult Parker for assistance if
required.
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 refriger-
ant 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).
