For conventional belt-driven TRUs, best practices recommend conducting comprehensive inspections at 750-hour intervals, and for both conventional and hybrid units, service intervals should be scheduled at 1,500-hour cycles or one year, whichever comes first.

Older reefers require routine servicing every 1,000 hours, but newer ones can go much longer. This SB series Thermo King reefer, for example, worked on here by Technicians at the CSTK dealership in Vineland, N.J., needs service only every 3,000 hours.

Oil and oil filter should be changed at the 3,000-hour interval on reefer units.
