 LIQUID REFRIGERANT RECEIVERS
HENRY TECHNOLOGIES LIQUID REFRIGERANT RECEIVERS
Receivers should be selected based on the operating charge for all
system components, including the liquid lines. It is usual to add
a small percentage to cover the refrigerant in long runs of suction
and discharge lines, etc. It is essential that the maximum operating
charge be determined, e.g., winter charge in air cooled condenser
having flooded head pressure control, this being much greater than
the normal summer charge.

The S-9010 regulator maintains the oil level in the compressor crankcase at
1/8-in. sight glass. The S-9010 maintains the level at any pressure differential*
between 5 and 30 psi.
The S-9010 oil level regulator is designed to bolt directly to the 3 bolt sight

The S-9090 maintains the level at any pressure differential* between 5 and 90
psi. If the oil level in the crankcase is too high or too low, the level can be
adjusted by turning the adjustment screw on top of the regulator. This can be
done while the system is in operation. Our exclusive design eliminates the
need of shutting down the system and disconnecting the oil feed lines in order
to adjust the regulator.

S-9090

S-9130 ADJUSTABLE REGULATOR

The S-9130 regulator allows the oil level in the compressor crankcase to be
maintained at any level between 1/4 and 1/2 sight glass.
The S-9130 maintains the level at any pressure differential* between 5 and 90
psi. If the oil level in the crankcase is too high or too low, the level can be
adjusted by turning the adjustment screw on top of the regulator. This can be
done while the system is in operation. Our exclusive design eliminates the
need of shutting down the system and disconnecting the oil feed lines in order
to adjust the regulator.

*Operating Pressure Differential — The difference between the oil fed to the
oil regulator and its compressor crankcase, where the regulator is controlling
oil level.

 OIL LEVEL REGULATORS (CONVENTIONAL)
HENRY TECHNOLOGIES ELECTRO-MECHANICAL OIL LEVEL REGULATORS
S-9030 Adjustable Regulator
The Electro-Mechanical Oil Level Regulator S-9030 provide a simplistic means
OIL LEVEL REGULATORS (CONVENTIONAL)

for controlling oil level for hermetic, semi-hermetic, reciprocating and scroll
compressors, through the use of a float switch and solenoid valve. A magnetic
reed float switch closes upon the reduction of oil level in the oil regulator body.
This action energizes the solenoid valve thereby feeding oil into the regulator
body.
The oil level is adjustable by loosening the compression nut and manually
adjusting the position of the float switch. A low level alarm is also provided, for
oil safety on hermetic and scroll compressors. If the oil level drops 1/8" below
the set point, a second magnetic reed switch closes activating a customer
supplied alarm. This alarm circuit may also be used to disconnect power from
the compressor. While the regulator is in alarm the solenoid valve remains open
trying to re-establish the oil level.

new refrigeration system, some oil will be absorbed by the
refrigerant as the system becomes balanced out. After two
hours of operation, the OIL RESERVOIR, if necessary,
should again be filled to the upper sight glass, and also
after two days, by which time the entire refrigeration
system should be balanced out. Then the OIL
RESERVOIR must be observed on each service call. No
oil should be added again until the oil level falls below the
lower sight glass port.

Existing System Start-Up

When installing this OIL CONTROL SYSTEM, on a parallel
system that has been in operation for some time, the
amount of oil should be added cautiously. With the
efficiency of the new OIL SEPARATOR, the oil return could
likely be sufficient to fill the OIL RESERVOIR to the lower
sight glass port only. Observe for one day. After the
second day, if the oil level has not risen to the upper sight
glass, add oil. If the oil level has risen above the upper
sight glass port, remove the excess oil from the OIL
RESERVOIR.

Our S-4004 Oil Filter removes foreign material from the oil as it
passes through the filter. The filter easily captures any debris
that may be in the system, such as dirt, metal chips, etc. (particle
retention 10 micron). The S-4004 is required on all Electronic Oil
Level Controllers to protect the solenoid manifold.

S-4005 POE Oil Filter & Drier for POE oil return on systems using Oil
Separators and Oil Control Systems. This is not a refrigerant Filter
Drier. It is designed to operate at a very low pressure drop in a
100% oil environment.

S-4005 POE Oil Filter & Drier was designed to clean and dry POE oil
as it is returned to the compressor crankcase or Oil Reservoir in
parallel systems. Clean and dry POE oil assures the proper operation
of the float assemblies in the Oil Separator and the Oil Level
