The system
The Greenbox is how a commercial truck keeps pressure maintained and the truck balanced, with the driver watching from the cab.
A wireless transmitter on a dual wheel equalizes pressure between those tires and monitors low and high pressure. The system also watches temperature. Dual wheels and single wheels are both in the film. The result the site is built around is simple: pressure maintained, truck balanced.
Request infoThe display in the driver’s cabin stores the date and time of a low-pressure, high-pressure, or temperature problem. The monitor face is marked for truck positions 1 through 6 and trailer positions 1 through 4, with Pre-trip and Learn controls. The driver can see the system where it is convenient in the cab.
Request infoOne kit covers the truck and the trailer. The film says about five minutes for one sensor and about forty minutes for the truck. Trailer installation is very similar. The closing line of the film: TPMEQS ensures optimal tire pressure and performance wherever you go.
Request info
Sensor bars with two hoses and brass fittings. A handheld receiver with a screen, power, and mute. A cabin display for pressure and temperature. A repeater, antennas, a power lead, and an optional chrome hub cover.
The current website also calls this an all-in-one package and says it is built in the USA. Those two lines are claims from the current site. The video shows the parts together in one box and does not repeat the USA line.
Dual or single? The system is engineered for commercial trucks and vehicles with dual wheels or single wheels. On a dual, one sensor connects both valve stems.
Truck and trailer? The monitor is marked for six truck positions and four trailer positions. The trailer install is very similar to the truck.
Where do the readings show up? In the cab. In the film, one screen shows 104 PSI and 53°F. That is a reading in the video, not a published operating range.
