The new Vanner Hybrid Beltless Alternator (HBA) is proven to provide more than 25% efficiency improvements over traditional alternators by using solid-state DC Converter technology.

At least 25% lighter than conventional alternators, the Vanner HBA improves fuel economy and reduces exhaust emissions, saving users hundreds of gallons of fuel and the associated exhaust emissions over the life of the bus.

Vanner’s HBA produces stable DC power at all temperatures and speeds, for precise and maintenance-free power for on-board accessories. All on-board electrical accessories such as interior lights, fare boxes and video cameras are provided with a dependable power source due to the elimination of transient power spikes that is inherent in alternator technology.

Its rugged design is built to last. With a target life of 10+ years, most HBAs will last for the entire life of the bus. Installation location and the innovative design eliminate safety concerns and maintenance problems associated with alternators which must be mounted to the engine and operate in a hotter and dirtier environment.

The Vanner HBA provides full power at curb idle to significantly surpass the performance and reliability of alternators. It delivers equal or more power than conventional OEM alternators through 85% of the drive cycle and the design eliminates the reduced or lost power experienced by traditional alternators when internal temperatures increase.
