ORBCOMM’s PT 6000 enables comprehensive fuel and temperature management, maintenance, logistics and regulatory compliance for refrigerated transport assets. Available as a cellular or dual-mode satellite-cellular version.

As part of a comprehensive telematics solution that includes sensors, connectivity and the CargoWatch application, the PT 6000 enables complete visibility and control of cold chain operations to help ensure the integrity of temperature-controlled cargo as it moves along the supply chain.

Two-way communications

Remotely set reefer temperature, change reefer state, initiate a defrost and more with two-way commands.

Alarms and notifications

Receive real-time alarms when specific conditions are detected—an active reefer is turned off, cargo area temperature deviates from the set points or does not match values specified by the order, an asset enters or exits a geofence, rapid fuel loss is detected and more.


The PT 6000 is compatible with every type of refrigerated unit for seamless installation and utilization. The device supports up to 3 temperature sensors to accommodate reefers with multiple zones and a rechargeable battery that reports for up to 10 days (depending on reporting frequency) when no vehicle power is available.

ORBCOMM’s PT 6000 is compact and has been built to operate in harsh environments. The device can be installed on the wall of a refrigerated trailer or inside a reefer cabinet. External LEDs communicate real-time status to facilitate installation and troubleshooting. A second serial port integrates additional RS232 sensors and systems
