Leading manufacturer of access and security solutions, dormakaba, has launched its first revolving direct drive. The direct drive’s ultra-thin design and modular functionality makes it a versatile solution for a wide range of installations. And because dormakaba’s direct drive does not include gearing components or transmission belts and chains, issues resulting from wear can be reduced.

One of the major down sides to conventional revolving door drive systems is susceptibility to wear – this can cause increased operating noise, uneven rotational movement or non-precise turnstile acceleration and deceleration. dormakaba’s new direct drive system for revolving doors has removed the need for belts or chains – therefore reducing the chance of wear to the drive. The new direct drive uses magnetic induction to rotate the revolving door panels. This is a more energy efficient and reliable solution, especially for buildings with high foot traffic such as commercial and office spaces.

The KTV3 and KTV4 revolving doors are now available with dormakaba’s new direct drive technology. The ultra-thin design of the direct drive makes the revolving doors sleeker and means the canopy height can be reduced to measurements from just 100mm. Modular functionality also makes for easy upgradeability, without the need to replace the motor or control unit, providing the adaptability needed to install across a wide range of projects.

Lee Chandler, Product Marketing Manager – Automatic Entrance Systems at dormakaba explains more: “The invisible direct drive system, control panels and reduced canopy height make the KTV3 and KTV4 revolving doors an elegant access solution. Providing a smooth, quiet door operation with a reduction in wear due to the elimination of gearing components and transmission belts and chains is a major benefit for the end user, as additional costs from maintenance can be reduced. Increased positioning accuracy also limits the temperature exchange between the interior and exterior of a building, reducing the chance of drafts.”
