Meritor, Inc. and Pressure Systems International (PSI) are making it easier for fleets to check wheel-end pressure output by expanding availability of an optional feature on their automatic tire inflation system.
The control box check point option was previously available on a limited basis with the Meritor Tire Inflation System (MTIS) by PSI. Now, it can be included with any MTIS by P.S.I. system purchased for new trailer installations or retrofits. With the new feature, the companies say maintenance personnel and drivers can check the regulated air pressure at the control box without shutting off the system and disconnecting the supply line from the control box.
The control box air pressure is set slightly higher than customers’ specified tire pressure. This is done by design so the system delivers the desired pressure to the tires after passing the check valves, the companies say.
“Fleets want a simpler way to change their desired system pressure or validate their current setting,” says Charlie LaFuente, PSI’s engineer and quality control manager.
By keeping tires properly inflated, MTIS by PSI improves tire maintenance management, trailer uptime and bottom-line ROI and reduces CSA (compliance, safety, accountability) violations, the company says. The simple and reliable design can be installed as new or as a field retrofit on any type of trailer, including van, liquid tank, logger, flat bed, chassis, livestock, platform, drop frame, dump, deep drop, doubles, dry bulk, reefer, auto transporter and military.
