Thermo King T-90 Series truck transport refrigeration units (TRU) are designed to burn less fuel as the unit cools and reduce the hours that the engine runs to decrease costs and save energy, says the company. The T-90 Series comes with standard integrated telematics hardware that easily connects fleets with their cargo. It features Thermo King’s SR Control System to ensure accurate temperature control and efficient operation. The series is available in T-90 MAX models which offer higher capacity, larger coils and heat exchangers, optimized compressor and engine speeds, and a sound-reduction kit.
