Open Scroll Air Compressor System
Each compressor shall be belt driven oil-less rotary scroll single stage, air-cooled construction with absolutely no oil needed for operation. Direct drive compressors shall not be used.
  • The rotary design shall not require any inlet or exhaust valves and shall be rated for 100% continuous duty
  • Tip seals shall be of a composite PTFE material and be rated for 5,000 hours operation.
  • Compressor bearings shall be external to the air compression chamber and shall all be serviceable for extended compressor life. Bearing maintenance shall not be required until 5,000 run hours. Compressors with bearings that are not accessible for service have a limited life span and shall not be accepted. Compressors shall have an integral radial flow fan for cooling and shall not require any additional electric cooling fans.
  • Each compressor shall have flexible connectors on intake and discharge, an electric drive motor, a discharge check valve, an air-cooled aftercooler, a condensate separator* and a high discharge temperature shut down switch.
  • Each compressor module shall have an isolation valve and a moisture separator* with automatic drain.


Motor
Each compressor shall be belt driven by a 1750 RPM, ODP, NEMA construction motor. Motors running at speeds higher than 1750 RPM shall not be acceptable. OSHA approved belt guards shall be provided.


Air Receiver
The system shall include an ASME air receiver rated for 200 PSI MAWP. The tank shall be equipped with:
  • A pressure gauge and a safety relief valve
  • By-pass valves to allow tank isolation without system shutdown
  • A sight gauge
  • An automatic electronic tank drain with manual override
The receiver shall be internally lined with an FDA approved material for corrosion resistance.


Premium NFPA Control Panel
The control system provides automatic lead/lag sequencing and automatic alternation of all compressors in order to equalize the amount of usage among the available compressors. The Premium NFPA Control Panel shall include a gateway server card and all features listed below:
  • Building automation communication gateway with BacNet® protocol and Web server features. Web server features include email notifications in case the system is in alarm or has achieved one of its maintenance intervals and requires service.
  • Ethernet port for connection to BacNet® server or direct connection to facility Ethernet for viewing of system operations and status via device IP-address UL508-A listed control panel in a NEMA 4/12 enclosure. The panel door will include:
  • UL508-A listed control panel in a NEMA 4/12 enclosure. The panel door will include:
    • 6” Color touch-screen
    • HOA (hand-off-auto) switch for each pump
    • 3-position Dryer control switch (dryer1-both dryer2)
    • 95 dba alarm horn
    • Acknowledge push-button (to silence the horn)
    The 6-inch color touch-screen will display:
    • Pump status: On, Off, or Ready
    • Pump Faults/Service state: High temperature,
    • overload trip, service required
    • Pump run hours
    • System pressure
    • System Dew-point
    • Trends
    • Pump information screens will display pump
    • maint intervals with required service
    • System alarm screen:
      • Low Pressure Alarm
      • General Fault Alarm (Pump faults)
      • Air Quality Alarm (Dew-point or
      • optional CO)
      • Pump Maint required
      • Dryer and monitor service notices
      • Alarm log
    Dry contacts are provided on a labeled terminal strip for remote monitoring of all system alarms.


Air Purification Package
The air purification package shall consist of the following: dual desiccant air dryers, dual filter and regulator bank with sample ports, and dew point monitor with alarms, and all bypass piping. Piping to be brass, stainless, or type K copper, and cleaned for medical air use. All components shall be mounted piped and wired to the air receiver.


Desiccant Air Dryers
The twin-tower, heatless desiccant air dryer is designed for a pressure dew point of -40 degrees F. Each dryer is sized to meet the full SCFM requirement of the system. The dryer shall be installed and plumbed on a common steel skid to the air receiver. The dryer design shall be of the automatic pressure swing, heatless, regenerative type and shall include a solid state cycle timer, reliable switching valve design, and purge muffler for quiet operation. Dryer controls shall include on/off/variable mode selector switch, and digital display.

The filtration system shall consist of 2 stages of filtration mounted and plumbed to the air dryer. The first stage of filtration shall include a centrifugal water separation and a 5 micron filter element with element coalescing vibration or a .01 micron or finer pre-filter with element change indicator and automatic condensate drain and installed upstream of the air dryer. The second stage shall include a 1 micron (or finer) particulate filter with element change indicator and installed downstream of the air dryer.


Filtration And Pressure Reducing Station
Each filter/dryer/regulator assembly shall be plumbed with bypass valves to enable service without disrupting air flow to the facility. Each assembly also includes a sample air port. The filtration systems consist of two stages of filtration as outlined above in the Desiccant Air Dryers section. Additionally, each assembly shall include:
  • A dual set of pressure reducing valves with pressure gauges shall be installed downstream of the final filters and shall be adjusted to an outlet pressure of 115 psig.


Additional Information
Each system is completely tested before shipment and includes:
  • Multiple oil-less scroll air compressors and associated equipment
  • Corrosion resistant air receiver
  • Desiccant air dryers with purge control
  • Control panel
  • Dew point monitor
The only field connections required will be system intake, exhaust, and power connection at the control panel. All interconnecting piping, wiring, and vibration isolation pads are included with the system.


Note
For Air Flow at 19 inHg, Compressor Capacity, System Full Load Current (F.L.A) at 208 V, System Full Load Current (F.L.A) at 230 V, and System Full Load Current (F.L.A) at 460 V values listed are with all pumps running.

10 hp systems will have one separator per two pumps.
