DESCRIPTION

GENERAL

Powerex Scroll Enclosure Air Compressors are designed to

supply continuous oil-free air by using the most advanced

scroll technology. These turn-key packages are extremely quiet

and offer electronic control that will reduce electrical power

consumption.

The Powerex Oil-less Rotary Scroll Air Compressor has

advanced scroll compressor technology through the

development of a completely oil-less unit. The Powerex Scroll

Compressor offers a dynamically balanced air end which

insures vibration-free operation. The rotary design permits a

continuous 100% duty cycle. No oil separation, oil filtration,

or inlet valves are required on the Powerex Scroll unit. The

compressor is virtually maintenance free.

The Powerex Oil-less Rotary Scroll Air Compressor is based

on the theory of scroll compression. A scroll is a free standing,

intricate spiral bounded on one side by a solid, flat plane or

base. A scroll set, the basic compression element of a scroll

compressor, is made up of two identical spirals which form

right and left hand parts. One of these scroll components is

indexed or phased 180° with respect to the other so the scrolls

can mesh. Crescent-shaped gas pockets are formed and

bounded by the spirals and the base plate of both scrolls. As

the moving scroll is orbited around the fixed scroll, the pockets

formed by the meshed scrolls follow the spiral toward the

center and diminish in size. The moving scroll is prevented

from rotating during this process so the 180° phase

relationship of the scrolls is maintained. The compressor’s

inlet is at the outer boundary of the scrolls. The entering gas is

trapped in two completely opposite gas pockets and

compressed as the pockets move toward the center. The

compressed gas is discharged through the outlet at the center

of the fixed scroll so no valves are needed.

property damage! Retain instructions for future reference.

SAFETY GUIDELINES 5.
PAGE 3
0 HP - 40 HP Scroll Enclosure Air Compressors GENERAL SAFETY CONT. 9. Do not wear loose clothing or jewelry that will get caught in the moving parts of the unit. Surface may be hot even if unit is stopped. 10. Keep fingers away from a running unit; fast moving and hot parts will cause injury and/or burns. 11. If the equipment should start to vibrate abnormally, STOP the unit and check immediately for the cause. Vibration is generally a warning of trouble. 12.

30 HP - 40 HP Scroll Enclosure Air Compressors INSTALLATION CONT. TRANSPORTATION BY CRANE Use openings at bottom of the unit to lift up by cable, lifting straps etc. Make sure all lifting devices are rated for the maximum load. SUGGESTED VENTILATION SYSTEM The temperature rise in the room must be kept to a maximum of 10 F. The BTU capacity of the vent system should be sized for the full operating HP rating of the compressor. Suggested fan capacity at 0 static pressure is shown below.
PAGE 5
30HP - 40HP Scroll Enclosure Air Compressors INSTALLATION Cont’d WIRING All wiring and electrical connections must be performed by a qualified electrician. Installations must be in accordance with local and national codes. Overheating, short circuiting and fire damage will result from inadequate wiring. The Powerex Scroll Enclosure Air Compressor is completely factory wired and requires only a 3 phase supply circuit.
PAGE 6
30HP - 40HP Scroll Enclosure Air Compressors INSTALLATION Cont’d GENERAL FAULT DRY CONTACT CONNECTIONS 1. Turn the compressor off and lockout the power to the compressor per OSHA standards. 2. Remove the door panel from the scroll cabinet to access the operating panel. 3. Output wires should be connected between terminals 10 and 11. The dry contacts are normally closed; when there is a fault or loss of power to the system, the contacts open. The contact rating is as follows: 240VAC/2A or 30VDC/2A, maximum.
PAGE 7
30HP - 40HP Scroll Enclosure Air Compressors INSTALLATION Cont’d SAFETY VALVES Safety Valves must be installed on every receiver. The flow capacity of a safety valve should be equal to or greater than the capacity of the compressor. 1. The pressure setting of the safety valve must not be greater than the maximum working pressure of the air receiver. 2. Safety valves should be placed ahead of any possible blockage point in the system, i.e. shutoff valve. 3.

30HP - 40HP Scroll Enclosure Air Compressors OPERATION Cont’d Go to PG 2 of the SELECT SETPOINT screen. Check motor rotation before operating the unit. Turn power on the unit and exercising extreme caution, use the HMI display/input screen to jog each motor. (To reach the JOG function, select SYSTEM STATUS from the MAIN screen, then select PUMP INFO for each installed pump/ motor set). Powerex wires the controls so all motors rotate in the same direction.
PAGE 9
30HP - 40HP Scroll Enclosure Air Compressors OPERATION Cont’d 5. Pushing the ON button beside the touch screen will allow the unit to start and operate automatically. Pushing the OFF button will stop the motors, but the HMI screen will remain active. 6. If the pressure does not rise, turn the unit off, the unit is running backwards. Have a qualified electrician switch the breaker OFF and exchange two out of the three phases of electrical source. If pressure is rising, allow the compressor unit to run.
PAGE 10
30HP - 40HP Scroll Enclosure Air Compressors OPERATION Cont’d The control automatically divides the range between HIGH and LOW Operating Pressure into equal operating intervals. The differential for the operating intervals may be adjusted by selecting STANDARD, MIN or MAX on the set up screen. In STANDARD, the differential will be automatically set to have a slight overlap between the individual pump intervals. Each interval will be 135% of the possible minimum value.
PAGE 11
30HP - 40HP Scroll Enclosure Air Compressors OPERATION Cont’d the root cause should be determined and corrected or motor damage may result. The user can activate the acknowledge function (button labeled ACKN) to allow the display to go back to SYSTEM STATUS or any other screen. Touch the VIEW button to advance to a screen showing which pump-motor assembly is in fault and for what reason. The fault will display and the affected pump-motor will be disabled until the RESET button is pushed.

30HP - 40HP Scroll Enclosure Air Compressors MAINTENANCE LOCKING OUT POTENTIAL TO PERFORM MAINTENANCE PROCEDURES The enclosure is equipped with the components to mechanically and electrically lock out both stacks of pump/motor assemblies. Proper OSHA lockout/tagout procedures should be abided by at all times. Electric potential to each motor can be locked out using the lockable motor protectors.
