RETARDER
.
The electromagnetic brake retarder is a secondary braking system which increases driving safety and reduces operating costs of buses, emergency vehicles, recreational motor home, and other heavy duty vehicles. The brake retarder is a self-contained unit that fits inline with your vehicle drive train. It operates independently of your normal service brakes and does not depend on any type of friction.
.
It is activated automatically by depressing the brake pedal or manually controlled by a multi-position switch on the dashboard or steering column. Sixteen powerful electromagnets exert a very strong drag force on two iron discs (rotors) attached to the drive train as they are switched on.
.
This creates a very effective braking (retarding) action with no actual metal-to-metal contact so there is no wear to the unit and much less wear to the standard service brakes. It is available in a variety of sizes and various capacities, and can be adapted for 12 volt or 24 volt systems.
.
The brake retarder provides dramatically increased driving safety in normal, as well as any number of special weather conditions including sandy roads, ice, snow or wet road conditions. It is designed to last the lifetime of the vehicle and more. Minimum maintenance (occasional wash downs) are necessary within the product life.

ADVANTAGES OF ELECTROMAGNETIC BRAKING RETARDERS

  • Reduce service brake maintenance costs
  • Reduced risk of engine overspeed
  • Extends service brake life dramatically
  • Increased resale value
  • Increased safety by reducing driver fatigue
  • Minimal maintenance such as occasional wash down
  • Improved driver control through smoother braking (retarding) provides better control in sandy, wet or icy-show conditions
  • Strong braking in half the normal distance. Compatible with ABS system
  • Slowing power when most needed in mountainous terrain keeps service brakes cool (no fade) ready for emergency situations
