Refrigeration system maker Thermo King is expanding its product offerings with the addition of a temperature control system for small trucks and new options for its PrimAir line of air management systems.

The V-520 temperature control system for small trucks features Thermo King’s Direct Smart Reefer (DSR) microprocessor for direct-drive refrigeration equipment is available in six models for box sizes from 10 to 18 ft.
