Advantages

Advantages

 N/A
  • Fleet management at your fingertips:
    Operating status and maintenance reminds are available via laptop, smartphone, or table. The compressor can be started remotely and geofencing feature prevents unauthorized use.
  • Maximum long-term efficiency:
    Thanks to an innovative coating that remains immune to temperatures up to 572 ºF, the blasted and phosphate-treated rotors show no measurable wear even after years of use.
  • Minimal downtime:
    Thanks to its generously sized fuel tank, the M500-2 can run for two entire sequential shifts and can even run continuously when connected to an external tank.

Low Life Cycle Costs

Low Life Cycle Costs

 N/A Our comprehensive approach to life cycle cost management: Superior efficiency, easy operation, service-friendliness, and a global service and consulting network with fast response times.

Sigma Control Mobil™

Sigma Control Mobil™

 N/A The compressor controller of the future
  • By accessing electronic motor management, the Sigma Control Mobil™ system optimizes compressed air availability and fuel efficiency. The system is both shock and vibration proof corresponding to IP 65 electrical protection.
  • Its functions include operational monitoring as well as precise system diagnostics.
User-friendly operation saves time
  • The highly intuitive user operation means that only three buttons are needed to operate the entire system.
  • In addition, the automatic monitoring feature can shut the compressor down as required. 
Precise settings
  • The system pressure can be set with precision of 1 psi directly on the Sigma Control Mobil™ display using arrow keys, as can the compressed air discharge temperature; this enables precise adjustment to downstream compressed air treatment components.

Refinery-Ready

Refinery-Ready

 N/A Sealed floor pan
  • The sealed floor pan for hazard areas immediately catches liquids to prevent any direct soiling of the floor or ground.
  • The drainage holes are sealed with screwed sealing plugs.
Spark arrestor
  • A certified spark arrestor is factory installed for use in areas at risk of explosion.
Shut-off valve
  • The engine shut-off valve automatically shuts the unit down upon intake of combustible gases.

Mobilair™ Fleet Management

Mobilair™ Fleet Management

 N/A Real-time data via GPS

An optionally available GPS/GSM modem (standard with M500-2) discretely integrated into the unit provides the user with online information regarding technical status of the machine. Should the user need to be alerted to an issue, the system actively reports it with a diagnostics check.
In addition to current operating hours and position-fixing, the system also helps by providing valuable data for compressor load evaluation and maintenance planning.

Additional Information

N/A For industrial equipment with high compressed air requirements the M500-2 ensures continuity of compressed air supply even during maintenance or renovation work. Other areas of application include refineries - e.g. for pipeline flushing. As a perfect team player, it easily integrates into existing stations.

Ready where it's needed, when it's needed
The two-stage, oil-free M500-2 is an ultra-reliable source of rental air for site work. It is also a perfect fit for backup air for manufacturing and process applications during plant maintenance periods, or to provide temporary auxiliary air during peak production periods.

Powered by the dependable 600 hp Caterpillar C18 diesel engine, the M500-2 is engineered for fuel efficiency and ease of operation. With a full load fuel consumption of 21 gal/hr and a 248 gallon fuel tank, M500-2 delivers up to 1600 cfm continuously for up to 12 hours. Run time can be extended using the external fuel connection (standard).

The Sigma Control Mobil™ matches air flow to meet varying air demand while maintaining steady pressure. With standard Proemion telematics, Kaeser fleet management is at your fingertips. Operating status and maintenance reminders are all available via laptop, smartphone, or tablet to avoid unscheduled downtime. M500-2 can be started remotely and the geofencing feature can prevent unauthorized use.
