Brake efficiently and safely.
With retarders, which were specially developed for commercial vehicles, up to 90 percent of all braking actions by heavy trucks can be performed without any wear. This is a significant safety advantage which pays off for you on the road in several ways. Because our retarders reduce the stress on the service brakes while reducing the costs for spare parts and maintenance. In addition, your transport capabilities are increased due to higher average speeds.
Your benefits at a glance
As a long-standing and close partner of vehicle manufacturers (OEMs) and transport companies, we know where the resources for greater efficiency lie: in reducing complexity, service, and material costs.
Our retarders meet these requirements in an exemplary manner. Therefore, our development partners and customers can rely not only on the reliability of our products but also on their durability and ease of service.

Hydrodynamic continuous braking system
Better braking – with retarders for commercial vehicles
High brake performance is essential when it comes to stopping a truck that weighs several tons. Classic friction brakes can reach temperatures of up to 1000 degrees under demanding conditions such as adaptive braking on the highway or on long downslopes. This leads to a rapid reduction in braking efficiency. Our retarders offer the ideal solution for this challenge, because the hydrodynamic endurance braking system brakes your vehicle safely and without wear. The service brakes are conserved efficiently, but are always fully operational in emergency situations.
It is no surprise that endurance brakes are a legal requirement throughout Europe. In this context, the best thing to do is to put your trust in Driventic’s efficiency and expertise.
Retarder design and operation
Hydrodynamics makes wear-free braking possible.
The magnitude of the braking torque depends on fill level and speed.
The retarder is perfectly integrated into the vehicle braking management system.
The braking energy is converted into heat and dissipated via the vehicle cooling system.
:quality(80):no_upscale())
The retarder portfolio – the right solution for every vehicle
Using an oil supply that is independent of the transmission fluid, the oil in oil retarders can tolerate the maximum permissible operating temperatures. The braking energy is transferred via the heat exchanger to the vehicle’s cooling circuit, where it is effectively dissipated.

Retarder 3250
The Retarder 3250 is a powerful and energy effi cient step-up retarder with its own oil supply. It is used in the Volvo FH and FM trucks series and buses with Volvo transmissions. In combination with the Renault Optidriver transmission, the Retarder 3250 comes in Renault Trucks in the T-Range and C & K-Range. In addition, the VR 3250 is also available in UD Quon & Quester Trucks in combination with the Ascot transmission.
Retarder 115DT
The Retarder 115DT is a step-up retarder with a high braking torque. It has a self sufficient oil balance and is integrated into the braking management of the vehicle. It’s an all-in-one solution with the new Mechatronic Retarder Control Unit (MRCU). The valve technology and damping plate, the pressure sensor and the electronic control unit (ECU) are all housed in a compact unit connected directly to the retarder. In combination with the service brake, it ensures optimal braking performance. At the same time, the retarder increases ride comfort with its v-constant function, maintaining constant “downhill cruise control” without activation of the service brake.

Retarder 115CT
The Retarder 115CT is a step-up retarder with a high braking torque. It has a self-suffi cient oil balance and is integrated into the braking management of the vehicle. In combination with the service brake, it ensures optimal braking performance. At the same time, the retarder increases ride comfort with its v-constant function, maintaining constant “downhill cruise control” without activation of the service brake.
Retarder 115HV
The Retarder 115HV is a powerful step-up retarder with its own transmission-independent oil supply. It is used in Mercedes-Benz commercial trucks Actros and Axor. It is integrated into the vehicle management system via the VERA retarder control and offers, among other things, the functions of driving speed limitation (limiter) and cruise control.
