Schmitz Cargobull presents new S.CU dc100 transport refrigeration unit with VarioFlow technology
Up to 8 per cent less fuel consumption, up to 11per cent more cooling capacity – the new S.CU dc100 combines maximum energy efficiency and precise temperature control with high operational safety, ease of use and low operating costs

September 2026 – With the S.CU dc100 presented at the IAA TRANSPORTATION 2026, Schmitz Cargobull is showcasing a new generation of transport refrigeration units and a new system in transport refrigeration technology. For the first time, VarioFlow technology regulates refrigeration generation and cooling/heat transfer independently of each other. By decoupling refrigeration and cooling/heat transfer, the new S.CU dc100 provides the power as required, creating the conditions for higher energy efficiency, lower operating costs, improved temperature control and a high level of operational reliability in everyday transport.
Compared to the predecessor model S.CU dc90, the S.CU dc100 consumes up to 8 per cent less fuel with up to 11 per cent more cooling capacity. At the heart of the system is a two-stage compressor that is directly connected to the diesel generator set, as well as new VarioFlow fans for the evaporator, condenser and machine room. In conventional transport chillers, refrigeration and cooling/heat transfer are directly coupled with each other. In the S.CU dc100 with VarioFlow technology, on the other hand, the speeds of the compressor, evaporator fan, condenser fan and engine room fan are individually adapted to the respective requirements, so that each component operates at optimum levels at all times. This provides the exact cooling capacity required for the respective transport and environmental situation.

The cargo space is cooled down from +30 °C to -20 °C around 15 percent faster
The demand-based control via VarioFlow technology also improves temperature control in the trailer. The continuous adjustment of the speeds of the compressor, as well as evaporator, condenser and engine room fans, enables precise temperature control with minimal energy consumption and supports the safe transport of temperature-sensitive goods in various extreme environmental conditions, summer and winter. The cargo space is cooled down from +30°C to –20°C around 15 per cent faster. The shorter pull-down time makes it possible to reach the required transport temperature more quickly. This also reduces the energy requirement during the cooling phase and supports the quality and safe transport of temperature-sensitive goods.
At high outside temperatures, reliability is increased by deliberately increasing the speed of the VarioFlow fans on the warm side (condenser and machine room). In addition, the optimised mode of operation reduces the load on the components and contributes to a longer service life of the system.
The S.CU dc100 is based on service-friendly 48-volt VarioFlow fans and a modular design with a high proportion of common parts within the S.CU modular system. This simplifies maintenance and service work and supports high vehicle availability.
The operation also remains unchanged intuitive. The user enters the desired machine setting as usual. The compressor and VarioFlow fans are controlled automatically. In this way, the S.CU dc100 combines easy handling with demand-oriented and efficient control of all essential components. For even more ease of use, the control panel has been tilted at the S.CU so that the information on the display is easier to read.
Schmitz Cargobull already introduced the R454A refrigerant in Europe for the predecessor model S.CU dc90 and the S.CU d80. It meets the stricter requirements of the EU F-Gas Regulation and has a significantly lower direct GWP (Global Warming Potential) value. Compared to the previously used refrigerant R452A, the CO2 equivalent is reduced by 89 per cent.
