The FRENELSA retarder installed in any type of vehicle for transporting goods, passengers and others, improves its performance in terms of safety, economy, comfort and sustainability thanks to its frictionless operation.

Advantages

Security

It absorbs 85%-90% of the vehicle’s braking needs, keeping conventional brakes cold so they can be effectively used when needed.

Economy

Significantly reduces the total cost of vehicle maintenance, multiplying up to ten times the useful life of all braking components (discs, pads…).

Comfort

The driving of the vehicle is much safer and more relaxed, being also a silent and progressive braking.

Sustainability

The use of the FRENELSA retarder considerably reduces the emission of fine particles from conventional friction brakes, minimizing the environmental impact and associated health risks.

Range

Chassis mounting

They are mounted between the transmission or gearbox and the differential of front engine vehicles (trucks and buses), between two pieces of drive-shaft.

These models cover a wide range of applications in industrial vehicles from 3 tons.

When assembling the retarder, the stator is fixed to the chassis with brackets and shockmounts, and the drive-shafts are fixed to the rotors.

Electromagnetic retarders for commercial vehicles

Mounting on transmission or differential

It is mounted on vehicles where the distance between the transmission and the differential is so short that mounting the retarder between two transmission sections is not possible.

When assembling these retarders, the stator is fixed to the transmission or differential housing and the rotors are fixed, on one side to the output plate of the transmission or to the input plate of the differential, and on the opposite side to the drive-shafts.

FAQs

What voltage does it work with?

Both with 12V and 24V depending on the vehicle.anto con 12V.

How is it controlled?

Manually through a lever on the dashboard and/or automatically through the brake pedal.

Does it suffer any wear?

No. As they are electromagnetic brakes, there is no friction or wear, so it also has the advantage that the emission of harmful particles into the environment is considerably reduced.

Does it need maintenance?

Depending on the application, our brakes can be maintenance free.

What advantages does it have over other systems?

They are cooled with air without the need for additional refrigeration systems.
Quick response on connection and disconnection.
High performance at low revs.
Easy installation and low maintenance.
Independent of the engine and gearbox.
Silent.
Progressive regulation

Is it convenient to install it in a hybrid/electric vehicle?

The FRENELSA electric brake is a very suitable complement for when the vehicle’s batteries are full and it is no longer capable of offering more braking.

Does FRENELSA help me with transportation, customs, insurance, etc.?

We ship our products all over the world and we have extensive experience in all transport, customs and insurance procedures. Our commercial department is in charge of the entire process until the products arrive at the customer’s home.

Can it be installed in a used vehicle?

Yes. Installation is feasible on both new and used vehicles.
