PREFACE
This manual describes the installation, operation, and
maintenance procedures of SGC, SGCB/H, and SGXB/H
Rotary Screw Compressors (referred to in this document
as SGC or SGX). The term SGC refers to the 1913, 1918,
2313, 2317, 2321, 2813, 2817, 2821, and 2824 SGC units, as
well as the 3511, 3515, and 3519 SGCB and SGCH units. The
term SGX refers to the 3519, 4013, 4018, and 4021 SGXB
and SGXH units, as well as the 3524 SGXB unit.
It is important that these compressors are properly applied
to an adequately controlled refrigerant or gas system.
Consult your authorized Johnson Controls-FRICK represen-
tative for expert guidance in this determination.
Proper performance and continued satisfaction with these
units is dependent upon:
• Correct installation
• Proper operation
• Regular and systematic maintenance
To ensure correct installation and application, select the
appriopriate equipment and connect to a properly de-
signed and installed system. The engineering plans, piping
layouts, and other system design materials, must be
detailed in accordance with the best practices and local
codes, such as those outlined in ASHRAE literature.
A screw compressor is a vapor pump. To ensure that
workinguidintheliquidstateisnotbeingingested,
peform the following steps:
• Select controls carefully. Ensure they are in good oper-
ating condition.
• Properly size piping and correctly arrange traps, if they
are necessary.
• Check that the suction line has an accumulator or slug-
ging protection.
• Know the load surges and make provisions for control.
• Check that operating cycles and stand still periods are
reasonable.
• Size high side components within the system and com-
pressor design limits.
It is necessary to keep the discharge temperature high
enough to prevent condensation of any moisture in the
compressor and oil separator.
DESIGN LIMITATIONS

LONG TERM STORAGE
Long term storage (6 months to 5 years) provisions are re-
quired, regardless of storage environment, if start-up and/
or useful operation does not occur within six (6) months of
equipment shipment. Special provisions may be required
for storage of less than six (6) months if the storage area
is subject to unusual environmental conditions such as
high humidity, large changes in temperature, or dusty
atmosphere.
The standard Johnson Controls-FRICK Warranty for an
SGC/SGX screw compressor covers twelve (12) months
from start-up or 18 months from shipment, whichever
comesrst.MakearrangementswiththelocalJohnson
Controls-FRICK service organization (arranged through
factory service) regarding surveillance and maintenance
during the storage period. It is the customer’s responsibil-
ity to submit a monthly report showing the condition of
the unit and noting any discrepancies to the guidelines
listed herein. Failure to comply with this Long Term Stor-
age recommendation may void the warranty.
Long term storage of equipment may lead to the dete-
rioration of components over a period of time. Synthetic
components in the compressor may deteriorate over
timeeveniftheyarekeptoodedwithoil.Awarmand
dry environment is essential to minimize environmental
and corrosion damage. Long term storage of the affected
equipment at a customer’s site may involve additional re-
quirements. Visit the Johnson Controls web site, www.jci.

PREPARING COMPRESSOR FOR STORAGE
If it is necessary to store the compressor for use at a later
date, peform the following steps:
1. Evacuate the compressor to remove moisture.
2. Connect the evacuation lines to port SM1.
3. Connect the evacuation lines to the three Schrader ac-
cess valves provided with the compressor. One valve is
connected to the compressor suction and the other two
valves are located at the block on the cylinder.
4. Break vacuum with dry nitrogen and bring pressure to 0
psig .
5. Pump oil into the SM1. Johnson Controls-FRICK rec-
ommends break-in oil P/N 111Q0831809 for storage
purposes. The amounts of oil needed for each compres-
sor are:
193 mm 12 gal 355 mm 35 gal
233 mm 15 gal 408 mm 50 gal
283 mm 25 gal
6. After the compressor is oil charged, pressurize to 15 psig
with nitrogen.
MAINTAINING COMPRESSOR IN STORAGE
• Ensure that the 5 psig to 15 psig nitrogen charge is
maintained. 15 psig is preferred.
• Rotate the male rotor shaft every two weeks. Mark the
shaft to ensure the rotor does not return to the original
position.
• Store the compressor inside a dry building environ-
ment.
• Grease the male rotor shaft to prevent rust.
• Record all information in a Compressor Long Term
Storage Log.
Contact Johnson Controls-FRICK Service with any
questions regarding long term storage.
DESCRIPTION
SGC/SGX COMPRESSORS
FRICK SGC/SGX rotary screw compressors utilize mating
asymmetricalprolehelicalrotorstoprovideacontinuous
owofvapor,designedforbothhigh-pressureandlow-
pressure applications. The compressors incorporate the
following features:
• High-capacity roller bearings to carry radial loads at
both the inlet and outlet ends of the compressor.
• Heavy-duty, four-point contact ball or angular-contact
bearings are mounted at the discharge end of the com-
pressor to carry axial loads.
• Balance pistons, located in the inlet end of the com-
pressor, reduce axial loads on the male axial bearings
to increase bearing life.
• Moveable slide valve to provide fully modulating capac-
ity control from 100% to approximately 10% (2824,
3519, and 4021 - to 15%; 3524 - to 20%) of full load
capacity.
• Volumizer
®
volumeratiocontroltoallowinnitely
variable volume ratio (Vi) from 2.2 to 5.0 for most SGC
models during compressor operation:
-2824, Vi = 2.0 to 4.1
-3524, Vi = 2.4 to 4.5
-4021, Vi = 2.2 to 4.3
• A hydraulic cylinder to operate the slide stop and slide
valve.
• For SGC/SGX models up to 355, housings constructed
of class 40 grey cast iron have a design working pres-
sure (DWP) of 400 psig. Those contrusted of ductile
iron or steel are rated for a DWP of 600 psig. For 408
compressors, 4013 models are rated for 700 psig, while
4018 and 4021 models are rated for 600 psig.
• Bearing and control oil vents to closed thread in the
compressor instead of suction pressure to avoid per-
formance penalties from superheating and displacing
suction gas.
• Shaft seal housing is designed to maintain operating
pressure on seal well below discharge pressure for
increased seal life.

INSTALLATION - OPERATION - MAINTENANCE
• Oil injected into the rotors to maintain good volumetric
andadiabaticefciencyevenatveryhighcompression
ratios.
• The shaft rotation is clockwise when facing the com-
pressor and is suitable for all types of drives.
Warning
Compressor rotation is clockwise when facing the
compressor drive shaft. Never operate the compressor
in reverse rotation as this results in bearing damage.
• SuctionanddischargeangesareANSIB16.1Class300
for all except the SGX 4013 model. SGX 4013 has Class
400suctionanddischargeanges.
• Integral suction strainers are provided for all models
except the SGX 35XX and 408 series. These models
must be ttedwithasuitablestrainer,#60meshx
.0065 in. diameter stainless steel wire or better, to pre-
vent damage to the compressor from particles entering
the suction area.
COMPRESSOR LUBRICATION SYSTEM
The lubrication system on SGC/SGX screw compressor units
performs several functions:
• Provides lubrication to bearings and seal.
• Provides a cushion between the rotors to minimize
noise and vibrations.
• Helps keep the compressor cool and prevents
overheating.
• Provides an oil supply to hydraulically actuate the slide
valve and slide stop.
• Provides oil pressure to the balance piston to help
increase bearing life. Some applications/operating
conditions require a regulated pressure to the balance
piston.
• Provides an oil seal between the rotors to prevent rotor
contact or gas bypassing.
• OnSGXmodels,providesoilsupplytothesqueezelm
dampers.
OIL PUMP
A demand oil pump is required for low differential pres-
sure applications. CoolWare™ provides a warning when
the oil differential pressure is too low. Oil being supplied
to the compressor from the oil separator is at system
discharge pressure. Within the compressor, oil porting
to all parts of the compressor is vented back to a loca-
tion in the compressor’s body that is at a pressure lower
than compressor discharge pressure. All oil entering the
compressor is moved by the compressor rotors out the
compressor outlet and back to the system oil separator.
AllSGXcompressorsareequippedwithsqueezelm
dampers (SFD) in the rotor blocking diameters. Depending
on operating conditions and power consumption, a full
time and full lube oil pump is required to supply oil to the
compressor (SB-3 and SB-4 ports) at a pressure up to 40
psi to 50 psi above discharge pressure. Coolware provides
the exact calculation at the actual operating condition. If
the calculation information is not available, ensure the oil
pressure is a minimum of 40 psi above discharge pres-
sure.
On all SGH compressors, the oil pressure to the balance
piston must be controlled and regulated through the SB-2
compressor port. For booster and low pressure applica-
tions, SB-2 may not need to be connected. For higher
operating pressure a balance piston regulator (BPR) must
be installed and piped to the SB-2 connection.
Since there are several variants of the BPR, use Coolware
to select the best option. Correct BPR information and
pressure settings are required. Do not run the compressor
without his information.
Notice
Do not run the compressor without the correct balance
piston regulator information and pressure settings.
CONSTRUCTION DETAILS
Housing
Castings for SGC/SGX screw compressors through model
3524 are close grain, pressure tight, and grey cast iron to
ensure structural integrity and mechanical and thermal
stability under all operating conditions. Ductile iron hous-
ings are also available for special applications.
Standard casing material for SGX 4013-4021 compressor
models is ductile iron grade 60-40-18 per ASTM A395
and ASME SA395. Contact Johnson Controls – FRICK sales
for additional information.
Rotors
The rotors are made from the highest quality steel bar-
stock or forgings to the exacting tolerances of FRICK de-
signedhigh-efciencyrotorproles.Thefour-lobedmale
rotor (5 lobes on 408) is connects directly to the driver.
The six-lobed female rotor (7 lobes on 408) is driven by
themaleonathinoillm.
Bearings
Antifriction bearings with L
10
rated life in excess of
50,000 hours at design conditions (using the FRICK Su-
perlter™) are used for reduced frictional horsepower and
superior rotor positioning. This results in reduced power
consumption, particularly at higher pressure ratios. Cy-
lindrical roller bearings are provided to handle the radial
loads and the thrust loads are absorbed by four point
contact or angular contact bearings. In addition, thrust
balance pistons are provided to reduce the thrust load
and improve bearing life.
Shaft seal
The compressor shaft seal is a single-face type with a
spring-loaded carbon stationary surface riding against a
cast iron rotating seat. The seal is capable of withstanding
static pressure up to 600 psig. During operation it vents to
low pressure to provide extended life.
The 408 compressors utilize silicon-silicon carbide seal
face material.

SGC/SGX ROTARY SCREW COMPRESSOR
INSTALLATION
Stepless capacity control
Capacity control is achieved by using a movable slide
valve. The slide valve moves axially under the rotors to
provide fully modulated capacity control from 100% to
minimum load capacity. Minimum load capacity varies
slightly with compressor model, pressure ratio, discharge
pressure level, and rotor speed. See the Table 1 for mini-
mum capacity for all SGC models.
The slide valve is positioned by hydraulic movement of its
control piston. When in the unloaded position, gas is by-
passed back to suction through a recirculation slot before
compression begins and any work is expended, providing
themostefcientunloading method available or part-load
operation of a screw compressor.
Volumizer variable volume ratio control
The FRICK compressor includes a method of varying the
internal volume ratio to match the system pressure ratio.
Control of the internal volume ratio eliminates the power
penalty associated with over- or under-compression.
Volume ratio control is achieved by using a slide stop, a
movable portion of the rotor housing that moves axially
with the rotors to control discharge port location. The slide
stop is moved by hydraulic actuation of a control piston.
The range of adjustment is listed in the Table 3.
Motor mount
SGC/SGX models through 3524 are designed with a drive
endangethatmateswithacastironmotormount(avail-
able as a sales order option). The motor mount is preci-
sion machined so that it ensures proper alignment of the
compressor and motor coupling.

DESIGN LIMITS
Information for all of the models is provided below. See
CoolWare to determine the limits for a specic application.
SGC/SGX compressor models are primarily designed to con-
nect to an electric drive motor using a tunnel mount. If the
application requires, the compressor can also be driven with
a foot-mounted motor. The tunnel mount ensures proper
alignment of the compressor and motor so that the shaft seal
and coupling operate properly. The rotor and bearing design
set limitations must not be exceeded (Refer to CoolWare).
Refer to 090.020-M - FRICK Compressor Control Panel for
additional information on set-point limits.
For proper piping, also refer to the FRICK package manual,
