During so-called service braking, the energy to be dissipated to slow down or stop a vehicle with a conventional braking system is so important that the components of the braking system, including the brake linings, undergo significant heating, which accelerates wear. Telma retarders ensure the vehicle's braking needs. Vehicles equipped with a Telma retarder can multiply the lifespan of their service braking system up to ten times: maintenance costs are therefore greatly reduced and operational availability is increased.

The exceptional reaction time of Telma retarders prevents excessive fuel consumption during fast switches between deceleration and acceleration phases. Telma retarders never operate against the engine: they can instantly stop producing braking torque upon driver's request.

The recognized quality, reliability and durability of Telma retarders make them a profitable investment that quickly pays for itself and, by extending the vehicle's braking ability, they increase the average operational speed.

An equipped vehicle has the advantage to reduce pressure on his brakes and consequently eliminate the risks associated to service brake overheating.

Therefore, using a Telma retarder is synonym of safety and comfort for the driver as well as for his passengers.

In addition, using a retarder is also a source of savings since it significantly reduces operating costs: frequency of brake pads replacement potentially divided by 8; reduced maintenance costs, and increased vehicle availability.

Last, using a Telma retarder is beneficial to the environment : indeed, there is no hydraulic circuit drain and no emission of particulate pollutants harmful to health. Yes, the Telma retarder is particularly efficient at low speed. This is the reason why it is the best solution for urban or stop-and-go type uses.

The full stop of the vehicle is still completed by the service brakes. The Telma retarder does not need to shut off when hot: it has sufficient cooling capacity, provided by the air flowing through its rotors, whose design is specific to this purpose. In addition, the retarder is selected based on the vehicle specifications so that, regardless of the Telma retarder temperature, it will remain efficient and fulfil its function. No, the Telma retarder cannot catch fire, even in the event of intense solicitation.

As any braking system, the Telma retarder transforms the energy dispersed during braking into heat. Consequently, a few installation provisions are recommended depending on conditions of use. Manuals, a list of spare parts, or information on Telma products and retarders are available from partner agents listed on our website.

However, Telma recommends periodic visual checks. However, please note that when hot, the retarder remains efficient and fulfils its function. The Telma retarder can be used regardless of the road condition.

It is designed to withstand severe external stresses. Please note that in the event of repeated use in severe conditions, Telma recommends increasing the frequency of visual checks.

The Telma retarder is designed to withstand extreme temperatures and severe weather conditions. The full integration of Telma retarders with electronic driver assistance systems guarantees the absence of risk associated with the use of a Telma retarder, regardless of the road grip conditions. No, a Telma retarder will not be the cause of premature tire wear. Tire wear is primarily due to a driver's driving style that would overuse the braking system, and not to the use of the retarder.

It is totally possible to install a Telma retarder on a vehicle in use. No: there is no risk of losing the manufacturer warranty, provided that installation has been made by a dealer of the vehicle brand or by a Telma agent who will be required to provide documents certifying the compliance of the installation.

Thank you for Subscribe to our Newsletter.For applications that do not require stall-speed loading, an air-cooled eddy-current absorber is usually the most cost-effective electric absorber you can buy. Its self-cooled rotors require no external water supply or resistor banks. It also costs less than our planetary-driven water brakes and allows far more design flexibility than hydraulic pumps. See Specifications or Models and Prices pages.

Loading when using these controls is adjustable — both manually using either its panel knob or the built-in volt analog control input or automatically via the non-analog PID-controlled leads from the DYNOmite data-acquisition computer. Everything, including the absorber, load control, and DYNOmite data-acquisition computer, can be run off of a large truck battery. Generator-based systems are also available, for performing longer duration testing than batteries may allow.

Perfect for torque reaction cradles where the higher inertia of an electronic absorber compared to that of a water brake is not an issue. Watch Micro-Eddy video! The keyed-shaft units are most commonly supported between a pair of pillow-block bearings. Alternatively, optional flat-flange models couple to matching bolt-pattern driveshaft U-joint assemblies. Need parts for an old eddy-current dyno? As a manufacturer of eddy-current dyno absorbers, we can often repair otherwise obsolete units.

Custom hybrid configurations can be designed using a combination of both a fast electronic absorber, typically an AC motor for great low-end torque control, together with a large eddy-current absorber. The latter inexpensively adds testing power and torque capacity. An AC absorber can also add motoring ability. Please call for more information.

Our larger eddy-current absorbers feature Zerk grease fittings for easier maintenance. These features are combined into a well-proven design — and one which strives to minimize both the cost and quantity of any, proprietary, moving wear parts. The end result is that costly testing-equipment maintenance and downtime becomes a non-issue. Call for immediate assistance in developing your own unique eddy-current absorber testing solution - or e-mail tech land-and-sea.

We have years of wide-ranging experience building one-off testing solutions or retrofitting older hardware with modern load control. Initial cold rotor torque foot-pounds and power Hp curves are for room-temperature rotors.
