OIL RESERVOIRS
Due to system design, loads & defrost cycles, varying amounts
of oil can be returned by the oil separator. Because of this, a
safety reserve of oil is required for the operation of our oil
control system. The oil reservoir is the holding vessel for this
stand-by oil. It has sight glass ports to observe the oil level
inside the vessel. The valve on top of the Oil Reservoir receives
oil from the Oil Separator, and the bottom valve distributes oil to
the Oil Level Regulators. The valves are backseating and have
a 1⁄4" flare connection, allowing the addition or removal of oil
from the reservoir. High pressure gas returns with the oil from
the Oil Separator to the Oil Reservoir. Pressure could increase
in the Oil Reservoir to adversely affect the Oil Regulators. To
prevent this, a vent line is installed from the top of the Oil
Reservoir to the suction line. This line permits the pressure in
the Oil Reservoir to be approximately the same as the suction
line and the compressor crankcases.
The 4 gallon model Cat. No. S-9108 should be used on very
large systems, or systems with excessive oil charges, long line
runs or any case where suction oil return may be impeded.
NOTE: Larger systems or compressors that discharge more oil
should use a 4 gallon reservoir. It is possible to pipe two identi-
cal reservoirs in parallel to increase the holding capacity. The oil
lines attach to the valves at the top and bottom should be teed
together. Selecting a size depends on customer preference.
