TU 900

Underfloor cooling – powerful and reliable

The benefits of the new MITSUBISHI underfloor unit TU 900 are used worldwide. Underfloor mounting allows e.g. higher cabs or lower box bodies, as no condenser needs to be mounted on the bulkhead of the box body.

Relocation of the condenser section under the box body also results in better load distribution with lower load on the front axle. This will also provide a quieter environment in the cab.

The user-friendly remote control gives you full control. You can conveniently adjust settings from the cab and control system functions via the digital display.

The robust chassis and trim components with proven corrosion protection, specially designed for underfloor use, ensure exemplary durability. Fuel consumption  can be reduced thanks to the  standard start/stop system,  the unique and efficient 3D scroll compressor and  the output control – it pays off.

The proven components from the MITSUBISHI Group are perfectly coordinated. This high level of vertical integration is the only way to guarantee a reliable and functional refrigeration system.


Easy maintenance

All major components requiring maintenance are easily accessible and have long maintenance intervals.


Low-maintenance evaporator fan due to generously dimensioned fan brushes, high quality collectors and collector bearings as well as hardened collector rings.


3D scroll 125.6 cm³ 

Electric motor

Powerful 5,5 kW Fuji electric motor, slow speed with high transmission, making it extremely quiet and durable, automatic phase detection.


Controls all system functions. Errors are indicated by error codes displayed on the remote control.


Automatic diesel start-up in the event of a power failure

The high cooling capacity is achieved thanks to the coordinated MITSUBISHI components.

The compact dimensions of the TU-series units offer the right size for every requirement.

The chassis and trim components are characterised by reliable corrosion protection.

The TU-series underfloor units have long maintenance intervals.

By using the compressor, the units produce low emissions and are reduced-noise (65–69 dB(A)).

With the start/stop system, you can save fuel despite the powerful electric motor.

The practical remote control in the cab makes it easier to control all system functions using the microprocessor.
