As the worldwide leader in transport refrigeration, Thermo King is engineering its newest trailer units, including the SB series single- and multi-temp units, to offer the lowest life cycle cost while delivering maximum performance with less impact on the environment. Thermo King also offers electric standby as an option on all of its trailer units, allowing the units to run on electric power rather than diesel. The result is less fuel burned and reduced emissions while the trailer is stationary in a loading dock or yard.
