High Speed Direct Drive Overhead Sectional Door

The DYNACO I-14 DD is an innovative overhead sectional door optimised for frequent use, car wash facilities, and corrosion-sensitive environments. This modern, robust, and flexible solution replaces a standard spring-based system with a stronger, more optimal motor and control system – a direct drive.

This springless door design enables easier, faster and safer installation. It increases the reliability of opening and closing. And, more importantly, it significantly reduces the risk of both wear and tear, and breakdowns. So, with the DYNACO I-14 DD, your business can keep on running – fast and efficiently.

Your benefits at a glance

  • Easier, faster and safer door installation
  • No spring contamination from rust or dirt
  • Reduced wear and tear, and downtime
  • High performing electrical direct drive system
  • Class 3 certification for air and water tightness

Heavy-duty demands

Repeated use. Water spray. Corrosive materials. In industrial and commercial operations, overhead sectional doors have to perform in demanding conditions. This can result in a range of problems, including rust and dirt contamination, increased wear and tear, and in worst case scenarios, complete breakdowns.

With the DYNACO OH1042DD, you have a springless, direct drive door that’s ready to keep driving your operations forward – even in the toughest of environments.

DYNACO I-14S Leaf Construction


The Dynaco I-14S overhead sectional door leaf has 42mm thick horizontal sections, connected together with hinges. Each panel is 545mm high. The outer hinges of each section have rollers that run in the tracks. The horizontal sections are insulated panels designed without thermal bridges for optimal insulation. The panels are filled with water blown CFC-free polyurethane.

The surface of the door leaf panels is characterized by the microrilled steel sheet. The pre-coated steel panels (steel pre-coated) for the door leaf fulfill outdoor corrosion resistance category RC3 according to EN 10169.

Top seal

Installed on the top panel to seal the gap between the panel and the wall. The double lip EPDM rubber top seal is mounted in an ABS adapter profile for optimal insulation and tightness.

Side seal

Installed on the track set to close the gap between the tracks and the door leaf. The double lip side seal design with insulation chambers ensures an optimal insulation and sealing.

Bottom seal

Installed on the bottom edge of the bottom panel, to act as a barrier as well as a shock absorber. The flexible EPDM rubber material and the O-shape provides continuous pressure on the floor, ensuring maximum sealing. The bottom seal is mounted in an ABS adapter for optimal insulation and reduced risk of condensation.

Wind reinforcement truss

Wider door panels and panels with windows are reinforced with metal profiles that act as trusses. These trusses reduce bending of the panel caused by wind loads or when the door leaf is in the horizontal position and is bending under its own weight. The truss is slooped to prevent objects being placed on it which could fall when the door opens. Nice plastic endcaps prevent dust being collected in the truss.

DYNACO I-14S Track Options

SL – Standard Lift

  • Building type: Most standard industrial buildings.
  • Benefits: Optimal design for common buildings.

The Standard Lift track set, with the spring package just above the door, is the most common solution

HL – High Lift

  • Building type: High ceilings. On the High Lift track set the spring package is placed high above the door.
  • Benefits: This track type allows high vehicles to cross along the door opening without obstructions of the horizontal tracks.

This track type is used when the space above the door is considerable, and is needed for work and traffic, e.g.: high vehicles.

VL – Vertical Lift

  • Building type: Very high ceiling and high working space requirements.
  • Benefits: Allows high vehicles to cross along the door opening without any obstructions.

If the space between the daylight height and the roof is sufficient, with this track type, the door can be opened vertically.
