Section 1 - 9600 Compressor Description

General

This manual provides the information required to install, operate, and maintain the CTI-CRYOGENICS 9600 Compressor .

NOTE: All personnel with installation, operation, and maintenance responsibilities should become familiar with the contents of both the 9600 Compressor Installation, Operation, Maintenance, and appropriate cryopump manuals to ensure safe, high quality, and reliable system performance.

CAUTION

Refer to “Appendix A - Customer Support Information” to contact the local Customer Support Center for information on connecting 9600 Compressors to a manifold with other CTI-CRYOGENICS compressors.

Compressor Configurations

The 9600 Compressor supports either On-Board or Cryo-Torr Cryopumps. For multiple cryopump installations, an On-Board Splitter Box or CryoTorr Interface can be used for cold head power distribution that reduces total cable requirements as shown in Figure 1-5 and Figure 1-6.

System Documentation

The manuals for a system cover two basic components: the cryopump and the Compressor. A manual is shipped with each system component to provide information for installation and operation of that component. A loose-leaf binder with index tab separators is also provided so you can compile a complete set of tabulated manuals.

CTI-CRYOGENICS Helium Refrigeration System

The operation of CTI-CRYOGENICS’ cryopumps is based upon a closed loop helium expansion cycle. The system is made up of two major

CTI-CRYOGENICS Helium Refrigeration System

components: the cryopump, which contains the cold head, and the helium Compressor which compresses the helium gas.

Refrigeration is produced in the cryopump cold head through periodic expansion of high pressure helium in a regenerative process. The high pressure helium is provided by the Compressor. Low pressure helium returning from the cold head is compressed into the necessary high pressure to be returned to the cold head. The energy required to compress the helium is rejected as heat through the cooling water.

High pressure room temperature helium is transferred to the cold head through the supply lines. After expansion, low pressure helium is returned to the Compressor (at or near room temperature) to repeat the cycle in a closed loop fashion. Large separation distances can be accommodated between the Compressor and the cryopump.

In the Compressor, helium is compressed using a highly reliable oil lubricated commercial Compressor. Helium purification takes place via several stages of oil removal. The final stage of purification is performed with a replaceable adsorber cartridge. In order to maintain peak efficiency, the adsorber must be replaced every three years. The 9600 Compressor is shown in Figure 1-1.

Section 4 - Operation

Adjusting System Helium Pressure

Your CTI-CRYOGENICS high vacuum pump system is comprised of several pressurized components i.e. compressor, flex lines, and cryopumps. Each component is charged with helium before shipment. After all cryopumps, helium lines, and manifolds are attached to the compressor, the system ("OFF" Condition) helium charge pressure must be verified before system operation. Once the ("OFF" Condition) helium system pressure has been verified, the system is ready for operation. After cooldown, the normal system operating pressure is recorded.

NOTE: The 9600 Compressor is designed for continuous operation and should remain ON even when the cryopumps are in a regeneration cycle.

"OFF" Condition Helium System Pressure Verification

The proper system ("OFF" Condition) helium charge pressure is necessary so that the cryopumps operate at maximum performance as well as to assure that the compressor will operate below the maximum design motor winding temperature which will maximize the life of the compressor motor.

1. Make sure the Compressor and Cryopump(s) are OFF.

2. Make sure all system components are connected together as described in “Section 3 - Installation”.

3. Allow all system components to acclimate to a temperature between 60º F and 80º F (15.5º C - 26.6º C).

4. Read the compressor helium pressure gauge located on the compressor rear panel as shown in Figure 1-4. Compare the gauge reading to the appropriate 50/60 Hz line frequency value (depending upon your system installation) indicated in Table 4-1.

Table 4-1: 9600 Compressor Helium ("OFF" Condition) Charge

Line Frequency Helium ("OFF" Condition) Charge Pressure

60 Hz 240 - 250 psig (16.5 - 17.2 bars ) 50 Hz 255 - 265 psig ( 17.6 -18.3 bars )

Compressor Operation

Exceeding the recommended system ("OFF" Condition) helium charge pressure will result in the compressor and cryopump safety relief valves opening and releasing excess helium gas.

Compressor Operation

NOTE: The use of a higher helium charge pressure for 50 HZ operation is necessary in order to compensate for the slower speed at which the compressor operates at 50 HZ. The ("OFF" Condition) charge level for 60 Hz remains at 240-250 PSIG.

CAUTION

5. If the ("OFF" Condition) helium charge pressure is not in the ranges as indicated in Table 4-1, then adjust the charge pressure as described in “Section 5 - Maintenance”.

CAUTION

While the 9600 Compressor is operating, the helium pressure gauge indicator should never be in the red zone. If the gauge indicator is below 65 psig, then the system must be checked for insufficient helium or helium leaks. If the gauge indicator is above 160 psig, then the system has been over pressurized. Refer to “Section 5 -

Maintenance” and either add or remove helium before operating the

9600 Compressor.

The system may be operated once the helium charge pressure is correct. Perform the following steps to start the compressor:

1. Set the System Circuit Breaker to the ON (UP) position.

2. Set the Control Circuit Breaker to the ON (UP) position.

3. Close all Cryopump gate valves.

4. Refer to the On-Board Module Programming and Operation manual or Cryo-Torr Cryopump Installation and Service manual (that came with your cryopump) and perform the cryopump start-up procedure.

5. Once the second stage temperature for all cryopumps is below 17K, record the compressor pressure gauge reading as the normal system operating pressure.

NOTE: During compressor operation, the compressor gauge reads the pressure of the gas entering the compressor prior to it being compressed.

6. Affix a copy of the data next to the compressor gauge on each compressor . This data is to be verified for each tool installa tion and whenever a configuration change is made affecting the amount of system helium gas and line volume.

The compressor pressure reading will decrease from the normal system operating pressure during cryopump regeneration or if fewer cryopumps are being operated. These are normal variations in the compressor pressure reading and should not be cause for concern.

If you have concerns about system performance changing, then check the normal system operating pressure which was determined in “Compressor

Operation” in this section. If the normal system operating pressure is not

correct, check the system for leaks.

Once the leaks have been repaired, helium must be added to return the system to normal operating system pressure as described in “Section 5 -

Maintenance”.

Replacement of Helium Circuit Components

On occasion, it may be necessary to replace components such as cryopumps, helium gas lines or compressors, or change the configuration of the system. Whenever any of these conditions occur, "OFF" Condition Helium System Pressure Verification should be performed to ensure that ("OFF" Condition) helium pressure has not changed.

CAUTION

The use of several compressors on a single manifold feeding a common supply header and a common return header requires special precautions. Contact CTI-CR YOGENICS for a review of the intended installation and for specific technical instructions. The use of a 9600 compressor on a manifold with other CTI-CRYOGENICS compressor models requires a reduction of the helium charge pressure to 200--210 psig charge pressure to avoid helium safety valves from inadvertently venting.

Adjusting System Helium Pressure

NOTE: These pr ocedur es can be performed on a compressor that is turned ON or OFF. However, the helium pressure gauge should be set to the ("OFF" Condition) helium charge pressure value if the compressor is turned OFF or set to the normal system operating pressure if the compressor is turned ON. Refer to “Section 4 - Operation” for more information.

Reducing Helium Pressure

NOTE: You must obtain the normal system operating pressure from the

“Compressor Operation” procedure in “Section 4 - Operation” in order to

perform this procedure. If the normal system operating pressure is unknown, then shut the compressor OFF and perform the “"OFF"

Condition Helium System Pressure Verification” procedure in “Section 4 Operation” instead.

1. Remove the flare cap from the gas charge fitting as shown in

Figure 5-3.

Gas Charge Flared Fitting

Helium Pressure Gauge

Gas Charge Control Valve

Figure 5-3: Helium Pressure Control Components

2. Open the gas charge control valve very slowly to allow a slight amount of helium to escape. Leave the valve open until the helium pressure gauge indicates one of the following:

• To the appropriate value in Table 4-1 if the compressor is OFF and

acclimated to a temperature between 60º F and 80º F

Adjusting System Helium Pressure

Increasing Helium Pressure

If helium is being added more than once every several months, check for leaks caused by improperly connected self-sealing connections or any mechanical joint in the Compressor.

(15.5º C - 26.6º C).

• To the value previously recorded in the “Compressor Operation”

procedure in “Section 4 - Operation” if the compressor is ON.

3. Close the gas charge control valve and install the flare cap.

Use the following procedure to increase the helium pressure if the indicated pressure is below the appropriate value as shown in Table 4-1.

CAUTION

Adding Helium

NOTE: You must obtain the normal system operating pressure from the

“Compressor Operation” procedure in “Section 4 - Operation” in order to

perform this procedure. If the normal system operating pressure is unknown, then shut the compressor OFF and perform the “"OFF"

Condition Helium System Pressure Verification” procedure in “Section 4 Operation” instead.

This procedure ensures that both the regulator and the charging line will be purged of air and that the air trapped in the regulator will not diffuse back into the helium bottle. For best results, CTI-CRYOGENICS suggests a dedicated helium bottle, regulator, and line, which are never separated, for adding helium.

NOTE: You are required to supply the helium charging line terminating in a 1/4-inch female flare fitting, and a two-stage pressure regulator rated at 0-3000/0-400 psig for this operation.

CAUTION

Use only 99.999% pure helium gas. Helium circuit contamination may result if a lower quality of helium is used.

1. Attach a regulator (0-3000/0-400 psig) and charging line to a helium bottle (99.999% pure).

NOTE: Do not open the bottle at this time.

2. Purge the regulator and charging lines as follows: a. Open the regulator a small amount by turning the adjusting

knob clockwise until it contacts the diaphragm, then turn approximately 1/8 to 1/4 turn more, so that the regulator is barely open.

b. Loosely connect the charge line to the helium pressure

regulator.

c. Slowly open the bottle valve, and purge the regulator and

line for 10 to 15 seconds. Turn the regulator knob counterclockwise until the helium stops flowing.

3. Remove the flare cap of the gas charge flared fitting on the rear of the Compressor.

4. Loosely connect the charging line from the helium pressure regulator to the 1/4-inch male flare fitting installed on the helium charge valve. Purge the charge line again, as in step a, for 30 seconds, and tighten the charge line flare fitting onto the gas charge fitting while the helium is flowing.

5. Set the helium pressure regulator to 300 psig (20.7 bars). If the compressor is ON, proceed with step a. If the compressor is OFF, proceed with step b.

a. Obtain the previously recorded normal system operating

pressure from the “Compressor Operation” procedure in

“Section 4 - Operation”. Open the gas charge control valve

very slowly and allow helium to flow until the compressor gauge reading is the same as the value obtained from

“Section 4 - Operation”. Quickly close the gas charge

control valve.

b. Obtain the appropriate (50 or 60 Hz) ("OFF" Condition)

system operating pressure from Table 4-1. Open the gas charge control valve very slowly and allow helium to flow until the compressor gauge reading is the same as the appropriate value in T able 4-1. Quickly close the gas char ge control valve.

6. Ensure that the helium charge valve on the Compressor is tightly closed. Shut off the helium pressure regulator on the helium bottle and remove the charging line from the male flare fitting. Reinstall the flare cap.
