Mini-Hybrid® Electric Cooling System: Transit Bus

The Mini-Hybrid® Cooling System is the original advanced cooling system that replaces the out dated mechanical cooling system for engine/vehicle cooling. The Mini-Hybrid® Cooling System entered the market in 2006 in the transit bus market as a concept and by 2010, the Mini-Hybrid® Cooling System is the standard cooling system used by transit bus manufacturers in North America.

The Mini-Hybrid® is ideal for retrofitting/refurbishing existing transit fleets. Benefits include better fuel economy, lower maintenance costs, improved safety by elimination of hydraulic leaks or fires, and improved emissions.
