TDS_ Rotary Screw Compressor
Installation
One application that typically requires higher discharge
temperatures (as high as 250°F) is natural gas gathering at
the wellhead. Moisture is normally present in the gas and
it is imperative that the discharge temperature be at least
40°F higher than the discharge dew point temperature for
the gas. Run Coolware with the “Water Saturated” block
checked to get the discharge dew point temperature for
your application. Oil temperatures as high as 170°F can
be used to achieve the necessary discharge temperature
to prevent moisture from condensing in the oil separator.
Contact Johnson Controls–Frick for additional information
for natural gas compression.
The main oil injection line that is connected to port SM1
must have a regulating valve to permit adjustment of the
oilowtomaintainthedesireddischargetemperatureat
all times.
The use of a three-way mixing valve is recommended
to keep the oil temperature in the normal range of 120°
- 140°F. The valve will provide warm oil to the compres-
sor quickly, reducing the pressure drop caused by cold,
viscousoil.Thisensuresproperoilowandtemperature
over the full range of operating conditions.
Oil lters
UseoflterelementsotherthanJohnsonControls-Frick
must be approved in writing by Johnson Controls-Frick
engineering or a warranty claim may be denied. Typical oil
lterspecicationis5micronabsolute(98.6%effecient)
per ISO 4572 to obtain the recommended oil cleanliness.
Oil pump
If your TDS_ compressor application requires an oil pump,
it is recommended that a strainer be mounted upstream
to protect it. Frick supplied pumps are a positive displace-
ment gear type that must have a safety relief valve to
ensure the oil pressure will not be more than 50 psi above
compressor discharge pressure for all models.
CAUTION
If oil pressure exceeds 55 PSI above compressor dis-
charge it could cause catastrophic compressor failure
due to male axial bearing failure. See CoolWare
™
for
your application’s requirements.
Oil heaters
Your package must be equipped with oil heaters that
providesufcientheattopreventcondensation from
occurring during shutdown cycles.
Compressor oil
WARNING
DO NOT MIX OILS of different brands, manufacturers,
or types. Mixing of oils can cause excessive oil foam-
ing, nuisance oil level cutouts, oil pressure loss, gas or
oil leakage and catastrophic compressor failure. For
most applications, CoolWare will select a specic Frick
oil for the gas/refrigerant being used. Depending on
the application, a different oil can be selected provided
it is of the proper viscosity and is compatible with the
gas/refrigerant and compressor elastomers.

fore installing the coupling.
Motor mounting (foot mounted only)
1. Thoroughly clean the motor feet and mounting pads of
grease, burrs, and other foreign matter to ensure rm
seating of the motor.
2. Attach the motor to the base using bolts and motor rais-
ing blocks, if required.
3. Weld the four kick bolts (not included with compressor)
into place so that they are positioned to allow movement
of the motor feet.
4. After the motor has been set, check to see that the
shafts are properly spaced for the coupling being used.
Check the appropriate Dimensional Outline drawing for
the minimum clearance required between the shaft ends
to change the shaft seal.
Compressor/motor coupling requirements.
Frick TDS_ compressors are arranged for direct motor
driveandrequireaexibledrivecouplingtoconnectthe
compressor to the motor.
With a foot-mounted motor, it is essential that the
coupling be properly aligned to ensure proper bearing and
seal performance.
1. Coupling must be selected and installed so that it doesn’t
transmit any axial load to the compressor shaft.
2. Set up the minimum distance between compressor shaft
and motor shaft to allow for seal removal (see Outline
drawings).
3. Coupling must be able to take up any misalignment
between motor and compressor. It is critical to the life of
the shaft seal that misalignment is kept to the minimum
possible value. Be sure to follow the coupling manu-
facturer’s guidelines for checking and correcting any
misalignment. See the next section for Johnson Con-
trols–Frick requirements.
Coupling alignment requirements
Coupling alignment must be performed prior to start-up.
After the compressor has been installed on the job site,
alignment must be checked again and if necessary cor-
rected prior to start-up. After a few hours operation, the
alignment must be checked while the package is still hot.
Correct hot alignment is critical to ensure the life of the
shaft seal and compressor bearings.
