Introducing Advanced Control and Emission Solutions for the Agricultural Industry
Hannover, 3 November 2025 — Dumarey is proud to announce its first-ever participation at Agritechnica – https://www.agritechnica.com/en/ the world’s leading trade fair for agricultural machinery. This milestone marks the company’s official entry into this sector, showcasing a portfolio of cutting-edge technologies designed to meet the evolving needs of agriculture applications.
Innovation Spotlight: Dumarey DEF System
Dumarey will unveil its own DEF System for heavy duty application, a cost-efficient, flexible, and easy-to-integrate Urea injection solution. Engineered for precision and performance, the system features advanced control strategies for accurate reductant dosing and SCR (Selective Catalytic Reduction) management.
This brand-new DEF system is made of:
– Heavy-Duty Reductant Delivery Units (RDUs) —up to two per system—offering customizable spray patterns tailored to customer specifications for optimal Urea atomization. The HD RDU is derived from light duty version (+ 40mio already in the field) to cope with more demanding heavy-duty requirements.
– Supply Module, developed by ActBlue France, that integrates Dumarey’s proprietary software—eliminating the need for external control units and simplifying installation.
What to Expect at the Dumarey Booth (Hall 15, stand B28)
Visitors to the Dumarey booth will discover a range of advanced technologies, including:
• Vehicle Control Unit (VCU)
A highly adaptable solution supporting electrified, hybrid, and fuel cell applications across passenger cars, commercial vehicles, and off-highway platforms.
• Dumarey Electronic Platform
A next-generation propulsion control unit offering maximum flexibility for energy generation and mobility applications, built on over 20 years of engineering expertise.
• DEF System Components
Visuals and technical insights into key elements:
o Supply module
o HD RDUs
• Gears, synchronizers, shafts and planetary carriers
These core components are used to build complete driveline systems that power modern agricultural machinery such as transmission, transfer cases or gearbox. With proven reliability across automotive, industrial, and off-road environments, they are engineered to meet the specific challenges of the agricultural field.
• 600 Series Flywheel
A compact, lightweight flywheel energy storage system designed for mobile and stationary applications with dynamic loads. Featuring a powerful direct-drive motor with integrated inverter and high-capacity (>2MJ) flywheel, it helps reduce fuel consumption, lower CO₂ emissions, and boost performance. Ideal for use in heavy-duty construction equipment, buses, rail, and off-highway vehicles.
• Hydrogen Engine
Hydrogen V8 6.6L – Port Fuel Injection Engine – Delivering up to 250 kW at 3000 rpm and 850 Nm at 2000-2500 rpm, this zero-carbon powertrain solution enables the efficient reuse of existing engine footprints for a seamless transition to hydrogen-based mobility.
