Meritor and Pressure Systems International announced the renewal of their strategic alliance covering the distribution of the Meritor Tire Inflation System by PSI in North America.

Meritor remains the exclusive distributor of MTIS by PSI for the commercial semi-trailer market and aftermarket in North America, selling a complete line-up of kits for new or retrofit installations. Pressure Systems International retains all responsibility for design and manufacture of the system, which includes ThermAlert technology, a high temperature notification system available on all MTIS by PSI kits.

There have been more than 350,000 MTIS by PSI units sold in North America. It can be installed on any type of trailer and automatically offers constant air pressure available when needed. The patented rotary union is the only moving part in the system, significantly reducing maintenance. ThermAlert adds wheel-end heat sensing technology to alert drivers to take preventative action that avoids damage due to elevated wheel-end temperatures.
