GDI Advantage

Ease of Installation: GDI door and gate operators are Plug-and-Play and dramatically reduce the time and expense of installing door and gate operator systems.  Our latest enhancement to our product line will further simplify the installation process

Simply mount the GDI operator and turn the operator on. For the newest generation of operators the system will verify the entire installation and indicate improper  connection situations.Upon the clearing of any deficiencies the  GDI products automatically calibrate themselves using a low-speed limit sensing operation, thereby eliminating the need for adjusting limit switches. In high duty cycle testing, GDI's system performed over 1,500,000 open/close cycles without requiring recalibration.

Automatic Calibration: During the initial setup, GDI operators automatically calibrate the amount of  force required in the closing cycle. Every GDI operator is shipped with default limits for obstruction Sensing and can be used out-of-the box without further adjustments.

Battery Backup: All of GDI’s door and gate operators are battery backup capable. The high operational efficiency of GDI operators combined with the SmartchargingTM capability of the control system enables uninterrupted operation for many cycles (50 to 200 depending on application) when commercial power is unavailable and under brownout conditions.

Soft start, Soft stop: GDI operators also have the capability to be fine tuned to unusual circumstances thereby  going well beyond just soft start/stop. Smooth custom acceleration and deceleration profiles are available, with extremely precise control, reducing wear on the system components. Accuracy of position control is repeatable and typically better than 0.020".

The two graphs below show speed and position profiles that GDI operators provide.

More about Advantages and Technology

History of the Development of the Algorithm(TM) Drive

GDI's product are based on technology development that started in 1993. We invested significant financial and engineering resources on the development of what at that time was the emerging technology of high speed electronic power switching and electronic motor commutation.

The engineering group developed our own proprietary electronic, software and electromechanical techniques and methods to control electric motors, especially effective in applications with start and stop torque requirements. These developments made it possible to operate our motors at higher efficiencies, with more precise control and to provide more power in a smaller package.

By 1999, the result was the implementation of manufacturable, advanced and in many ways, breakthrough electric motor and controller technology. Patents have been issued and others are to be applied for. Patent protection will continue to be a part of this development of software, electronics and electromechanical technology.

The OEM versions of the GDI operators are being utilized by leading companies in their markets and installed for horizontal and vertical door applications in the cold storage, pharmeceutical and commercial door industries as well as for traffic control applications. Thousands of these operators are working in the field, under very high utilization rates and severe temperature environments. Our operators are designed for millions of cycles of operation.

GDI's core technologies are its AlgorithmTM Drive (below) and NetworkPowerTM

 ALGORITHM(TM) DRIVE
The Algorithm(TM) Drive technology utilises new design parameters for the motor-controller transmission system, dramatically increasing the efficiency of energy usage and reducing the size of the motor in many applications.
