Door Dampers: Precision Protection for Every Door System

Modern infrastructure demands efficient, safe, and long-lasting components—and door systems are no exception. ACE’s high-performance door dampers offer exactly that, preventing damage to doors, frames, and surrounding structures by absorbing harmful impacts during operation.

Whether installed in elevator systems, automatic doors, or manually operated doors, ACE TD and TDE dampers ensure safe and controlled door movements. Designed to manage impact velocities from 0.1 to 2 m/s and up to 10 strokes per minute, these dampers are ideal for environments where reliability and repeatability are essential.

Key Features at a Glance

• Adjustable damping force: Set independently for each side using a knurled head on the piston rod.
• Energy absorption: From 75 Nm/Cycle up to 190 Nm/Cycle, depending on configuration.
• Stroke lengths: Between 50 mm and 120 mm, suitable for a wide range of applications.
• Durable materials: Zinc-plated steel cylinder tubes and hard chrome-plated piston rods ensure longevity.
• Customisable design: ACE offers tailored solutions with special lengths, characteristic curves, and seal options upon request.

TD-28 and TDE-28 Models: Safety in Every Stroke

The TD-28 and TDE-28 variants bring an extra layer of safety and adaptability to any setting. With a compact outer body diameter of 28 mm and a piston rod diameter of 8 mm, they’re designed to fit seamlessly into door systems while offering exceptional performance.

These dampers can withstand impact forces from doors weighing up to 7,000 kg, depending on the installation type. The adjustment mechanism allows easy tuning of the damping force, while maintaining reliable performance throughout a wide temperature range of -20 °C to +80 °C.

Applications

• Elevator doors
• Commercial and industrial hinged or sliding doors
• Automatic entry systems
• High-end furniture and cabinetry
• Building technology requiring controlled motion

With their combination of durability, adjustability, and safety, ACE’s door dampers are the perfect solution for protecting doors, users, and the surrounding environment from damage or wear.
