SABROE CMO single-stage compressors – Small single-stage compressors with swept volumes of 100–270 m3/h

CMO compressor units are small units specially designed for use in smaller-scale refrigeration installations where reliability is a particular concern, and uninterrupted service a big priority. They are an economical, low-maintenance solution for smaller-scale, heavy-duty refrigeration installations, and are most commonly used as stand-alone units operating at full load, or as small back-up compressors.

Range

Six different models are available to provide swept volumes of between 97 and 273 m3/h.

Advantages

  • High coefficient of performance (COP), with excellent performance even under part-load conditions
  • Special design ensures low noise and vibration
  • Variable-speed drive (optional) provides stepless capacity control over the entire operating range
  • Repairs can be undertaken in situ, without removing the compressor
  • Easy to access for service, with limited spare parts requirements

Benefits

  • Low power consumption, which greatly reduces operating costs
  • Wider range of possible mounting locations, and minimal expenditure on noise attenuation systems
  • Power consumption and operating costs kept to a minimum
  • Lower repair costs and less downtime
  • Easy, inexpensive maintenance, which helps limit downtime and reduce operating costs

Options

  • Unisab III systems controller
  • Variable-speed drive line (Unisab always included)
  • Gauges, thermometers and temperature/pressure control
  • switches
  • Extended cylinder capacity control
  • Oil level regulator (for use in parallel systems)
  • ATEX-compliant configuration
  • Oil separators with coalescing element
  • Special vibration dampening.

Additional Features

• Circuit Breaker Protection for Main Power.
• UL, cUL, and ISO 9001 Certifications
• Flexible Analog Inputs Setup is easily changed in the field to accept 0-5 volt, 1-5 volt, 4-20 mA or ICTD sensors and
transmitters.
• Long-Life, Easily Replaceable, Lithium Coin Cell Battery for power backup to the time/date clock only.
• Communication Activity and Diagnostic Lamps simplify troubleshooting and provide visual indication of proper component
operation. Code readouts also appear on the display if an internal component problem is detected.
• FLASH Setpoint Memory All setpoints are stored in FLASH memory which requires no battery backup. Setpoints can be
field programmed within Johnson Controls defined limits. A notice is displayed if setpoints are entered outside of the
defined ranges.
• Replaceable Input and Output Modules with individual, replaceable fuses, on-board tester, and spare fuse.

Software
• Intuitive Operator Interface All of the Quantum™ HD control panel screens are user friendly, menu driven and easy
to use and understand. The straight-forward menu design keeps you on track.
• Software Diagnostics Numerous diagnostic features have been incorporated to ease troubleshooting and identify
component malfunctions. Diagnostic features include: sensor short/open, setpoint input out of sensing range, DC and AC
power monitoring, and memory error sensing.
• Multiple Capacity Controllers provide application flexibility for auto setback control and control reset for changes in
modes of operation.
• Override Controls All safety and controller functions can be programmed to unload the compressor within maximum
safety and control parameters.
• On-screen Calibrations for sensors, motor current, slide valve and slide stop with easy to understand graphics. Potentiometer tuning has been eliminated.
• Shutdown Notification Display backlight flashes on shutdown to attract attention in noisy engine rooms.
• Selectable Pressure and Temperature Units
• Programmed Compressor Sequencing
• Condenser Control
• Industry Standard Communication Protocols
• Real-Time and Historical x-y trending Selected data and selected time periods can be viewed in either an x‑y trending
chart or a tabular chart.
• Ability to add analog inputs Can add any 0‑5Vdc, 1‑5Vdc, or 4‑20mA sensor. A name and unit description can be entered to identify the input. The inputs have high and low alarm and shutdown setpoints.
• Ability to add digital inputs A name can be entered to identify the input. Either an alarm or shutdown can be selected
to occur when the input is de-energized. A selection can be made whether to monitor the input continuously or only when the compressor is running.
