Refrigerated Vehicle E-Conversion: Lower TCO & Maintain Custom Bodies
The electrification of refrigerated fleets is inevitable, yet purchasing new electric vehicles often means losing expensive specialized bodies. A D2E (Diesel-to-Electric) conversion for your Mercedes-Benz Sprinter 907 preserves your capital, lowers the TCO, and ensures compliance with the Clean Vehicles Directive.
The topic briefly and concisely
Meet the 38.5% CVD quota for light commercial vehicles quickly and cost-effectively by retrofitting existing refrigerated vehicles.
Reduce your Total Cost of Ownership (TCO) through considerably lower maintenance costs and significantly reduced energy costs per kilometer.
Secure your investment by continuing to use your expensive, specialized refrigerated body on the proven Mercedes-Benz Sprinter 907.
Fleet managers in temperature-controlled logistics face a dual challenge: the legal requirements of the Clean Vehicles Directive (CVD) demand rapid electrification, while the high investment costs for new electric refrigerated vehicles and the associated loss of the valuable refrigerated body threaten profitability. The HEERO conversion for models such as the Sprinter 313, 316, 319, and 324 offers a pragmatic solution. It enables the continued use of your proven vehicle and specialized body, significantly reduces the total cost of ownership (TCO), and ensures compliance with the procurement quotas of 38.5% for light commercial vehicles.
Regulatory pressure: The Clean Vehicles Directive as a driver
The Clean Vehicles Directive (CVD), implemented in Germany by the Clean Vehicles Procurement Act (SaubFahrzeugBeschG), forces public contracting authorities and their service providers to take action. By the end of 2025, 38.5% of all newly procured light commercial vehicles had to be classified as "clean", which in practice often means electric vehicles. This quota affects not only municipalities directly, but also private logistics companies operating on behalf of the public sector, for example in waste disposal or passenger transport. Non-compliance with these requirements can lead to severe consequences and jeopardize participation in future tenders. The conversion of existing refrigerated vehicles is the fastest way to meet this quota without disrupting operations through lengthy new vehicle ordering processes. A conversion of a Sprinter 907 takes a maximum of 10 working days at HEERO (only model series 907). This efficiency enables a timely adaptation of the fleet to the legal framework.
TCO Analysis: Why Retrofitting Outweighs New Purchase
The decision between a new purchase and a retrofit is significantly determined by the Total Cost of Ownership (TCO). A new electric van with a refrigerated body represents a capital investment that is often 50% higher than that of a retrofit. The decisive factor is the preservation of value of the special body, which would be completely lost in a vehicle change. The operating costs of a retrofitted electric van are significantly lower than those of a diesel vehicle. Maintenance costs can decrease substantially, as maintenance-intensive components such as the exhaust system and oil changes are eliminated. In addition, the energy costs per 100 kilometers for electricity are typically significantly cheaper than for diesel. Another advantage is the exemption from vehicle tax until 2030. Taking all factors into account, the investment in a retrofit often amortizes within 3 to 5 years.
Your advantages at a glance:
The retrofit offers clear economic and operational advantages:
Capital preservation: Your expensive and often custom-made refrigerated body remains fully preserved and functional.
Lower investment: The costs for the retrofit are significantly lower than purchasing a completely new electric refrigerated vehicle.
Minimal downtime: The retrofit of a Sprinter 907 is completed in a maximum of 10 working days (only model series 907), whereas delivery times for new vehicles often take several months.
Reduced operating costs: You benefit immediately from lower energy, maintenance, and tax costs.
These factors make the retrofit the strategically wiser choice for forward-looking fleet operators.
Technical Implementation: Performance and Reliability for the Cold Chain
The technical performance of a converted refrigerated vehicle must meet the demanding conditions of cold chain logistics. The HEERO system for the Mercedes-Benz Sprinter 907 is based on a 110 kWh battery, which enables a realistic WLTP range of up to 300 km. It is crucial that the operation of the cooling unit does not unpredictably affect the range. Our system integration ensures that the power supply for the refrigeration is self-sufficient and efficient, so that the cold chain is maintained seamlessly even during long stops or in urban traffic. The charging power of 165 kW at a DC fast-charging station allows charging to 80% in just 60-90 minutes, which fits precisely into the legally prescribed driving and rest times. A 22 kW AC charger is available for planned depot charging overnight. The performance of the electric motor ensures a dynamic and quiet drive, which is particularly advantageous in urban delivery traffic. With our solutions for special-purpose vehicles, we guarantee that the specific requirements of your operations are fully met.
Operational Excellence: Fleet Integration and Service
Successful electrification goes beyond the vehicle and requires thoughtful integration into fleet processes. HEERO supports fleet managers in planning and implementing the necessary depot charging infrastructure and offers intelligent load management to avoid costly peak electricity demands. Our mobile service technicians, the "Flying HEEROs", ensure high vehicle availability through maintenance and service directly at your location. This minimizes downtime and keeps your logistics processes running. The range of up to 300 km easily covers typical daily routes in distribution transport and the last mile, even in winter operation. Through the combination of a proven vehicle basis, reliable e-technology, and a comprehensive service concept, the conversion of your box truck becomes a secure and future-proof investment.
FAQ
How long does a refrigerated vehicle Diesel-to-Electric (D2E) conversion take?
The D2E conversion of a Mercedes-Benz Sprinter (model 907) is typically completed by HEERO within a maximum of 10 working days (model series 907 only). This significantly minimizes your vehicle's downtime compared to the often months-long delivery times for new vehicles.
What is the real-world range of a Diesel-to-Electric converted refrigerated vehicle?
A Sprinter converted with the HEERO system achieves a WLTP range of up to 300 km. The power supply for the cooling unit is integrated in such a way that the range remains predictable, and the requirements of cold chain logistics are reliably met, even in winter.
What happens to the warranty on my vehicle?
HEERO assumes the warranty for the entire electric drivetrain and all components installed by us. The warranty for the untouched parts of the base vehicle remains unaffected. Our service team of "Flying HEEROs" is at your disposal for all matters.
Is the Diesel-to-Electric conversion more cost-effective than purchasing a new electric refrigerated van?
Yes, in most cases, retrofitting is the more economical solution. You avoid the depreciation of your expensive refrigerated body and benefit from a significantly lower initial investment. Lower operating and maintenance costs lead to an attractive TCO and rapid amortization.
Which Mercedes-Benz Sprinter models are eligible for our Diesel-to-Electric (D2E) conversion?
Our D2E conversion system is specifically designed for the Mercedes-Benz Sprinter 907 series. This includes common base models such as the 313, 316, 319, and 324, which are frequently used as the basis for refrigerated vehicles. Contact us for an analysis of your specific fleet.
