S.KO CITY semi-trailer box and transport refrigeration unit S.CU mt-DualEvap: efficiency and flexibility for urban food logistics

June 2026 – With the S.KO CITY box body and the S.CU mt-DualEvap transport refrigeration unit, Schmitz Cargobull is presenting a transport solution that is specially designed for MultiTemp use in urban distribution transport. The compact and manoeuvrable S.KO CITY refrigerated trailer offers a high payload as well as flexible equipment options, which, in combination with the new transport refrigeration unit S.CU mt-DualEvap, a variant specially developed for food distribution transport with an integrated longitudinally divided evaporator  in the main unit, make daily operations more economical and predictable.

A key advantage of the new S.KO CITY is the optimised weight distribution thanks to the newly positioned kingpin. This increases the payload by up to 1,400kg and shortens the overall length by 52cm. For operators, this means significantly higher transport capacity per trip, fewer trips and correspondingly lower costs per pallet. The reduced distance between the tractor and the trailer also improves aerodynamics and reduces fuel consumption and CO₂ emissions.

With a length of nine metres (22 Euro pallets) and a robust 10-tonne axle, the S.KO CITY combines high capacity with high manoeuvrability. Mechanical forced steering makes manoeuvring in narrow city centres easier and reduces time, tyre wear and the risk of damage. The energy-efficient FERROPLAST® body in combination with the new S.CU mt-DualEvap is specially designed for food and distribution transport.

Since the S.CU mt-DualEvap does not require an additional ceiling evaporator, the full interior height is available. This increases the load volume and improves air circulation. Longitudinal partition walls with predefined transverse partition options from 830mm to 1,250mm enable the trailer to be precisely adapted to different delivery concepts. Thanks to the final transverse partition wall, the sizes of the temperature-controlled chambers can be adjusted according to the load, and empties can also be returned economically. Three powerful evaporator fans integrated into the bulkhead enable uniform air flow. This reduces complexity and increases operational reliability. At the same time, the compact design ensures rapid cooling down – a clear advantage for frequent door openings in distribution transport. The modular system of the S.CU simplifies maintenance and repair. Components are easily accessible, downtimes are reduced.

Intelligent system networking for high availability

The S.KO CITY is equipped with the Body Control Unit (BCU), which acts as a central control unit to network all relevant system components of the trailer. In combination with the new central electrical box, it increases reliability and enables faster diagnosis. This increases the vehicle's operational readiness and creates the basis for condition-based and predictive maintenance.

In addition, the BCU expands the telematics functions and improves the energy management of the trailer. This extends the battery life of the cooling unit and reduces the risk of failure in daily operation. The refrigeration unit battery is charged via the tractor's RDF connector and is protected from deep discharges. The charge status can be conveniently viewed at any time via the TrailerConnect® portal.

Practice-oriented equipment details also make everyday work processes easier. Continuous LED interior lighting ensures optimum visibility during loading and unloading, especially at night. The airline floor is non-slip, hygienic and easy to clean and offers flexible options for load securing. With the S.KO CITY and the new S.CU mt-DualEvap transport refrigeration unit, Schmitz Cargobull offers a solution for urban refrigeration and food logistics. The combination of maximum loading volume, efficient refrigeration technology, high manoeuvrability and optimised aerodynamics improves efficiency along the entire transport chain.
