KAC Building: on 10.000 sq ft. KAC has 5 installation lanes with modern tooling to provide a swift and clean installation. Office and logistical infrastructure are on site.

Training Rig: KAC does provide in house training to dealers and installers with hands on mechanical and electrical props.


KAC is taking care of the international demand in North America by carrying over 200 retarders in stock with a complete inventory of spare parts.
KAC is training and recruiting dealers and installation companies with its own training facility, “in house”.
The product quality of retarder systems depends largely on the experience and quality of the installation technicians. The constant training of our own personnel is, therefore, also of the utmost importance.
