Advantages 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 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™ The compressor controller of the futureBy 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 timeThe 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 settingsThe 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 Sealed floor panThe 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 arrestorA certified spark arrestor is factory installed for use in areas at risk of explosion.Shut-off valveThe engine shut-off valve automatically shuts the unit down upon intake of combustible gases. Mobilair™ Fleet Management Real-time data via GPSAn 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.
