Idle Free Flex System

Idle Free Flex Systems are “key off” idle reduction technologies for work trucks trusted by Department of Transportation and municipal fleet managers throughout North America. Without having to idle the truck engine, Flex Systems provide up to 8 hours of interior cabin heat, engine heat for cold starts, power for communication devices and interior, exterior, and safety lights. Using a Flex System allows fuel savings with the reduction of truck idling, reduced repair and replacement of the diesel particulate filter, increased engine life and decreased maintenance intervals, and helps reduce a truck’s carbon footprint with lower CO2 emissions.
