Underground hydraulic operator SUB BT

  • Brand
  • TypeUnderground gate
  • Underground hydraulic operator SUB BT, low voltage, in-ground irreversible hydraulic operator for hinged leaves up to 2,5 m. weight 800 kg.

Overview of the underground hydraulic operator SUB BT

The SUB BT underground hydraulic operator from BFT (Italy) is a premium solution designed for projects that demand superior aesthetics and exceptional durability. With the capacity to handle gate leaves weighing up to 800 kg, SUB BT delivers smooth, safe, and elegant operation for a wide range of applications, particularly automatic gates for villas and high-end developments that require sophistication.

Installed underground, the system remains virtually invisible once completed, preserving the overall architectural design while ensuring optimal performance.

Main features of SUB BT

Control unit with programming display and new, simplified scenario-based programming
Fully adjustable mechanical stops inside the operator
The monoblock structure gives the possibility of a very neat installation that is extremely reliable over time.

Technologies

ER - READY

The new coding system for direct cloning of remote controls Based on microprocessor technology, this system allows the cloning of any MITTO remote control in a MITTO REPLAY remote control. In fact, the first remote control “teaches” the second one the correct code which is automatically saved in the receiver the first time it is used. Everything occurs at the highest levels of security thanks to the use of the Rolling Code safe transmission system.

EE LINK

For fast and safe programming. EELINK is a system developed by BFT which, by means of connection to handheld programmers (Unipro, Uniradio and Proxima), makes it possible to transfer data from automatic systems to PCs and vice versa. Thus EEdbase or U-base, the databases of the information stored in the installed systems, are constantly updated. Thanks to this software it possible to associate the necessary personal details with each system: owner’s address and details, name of maintenance technician, names of every remote control holder, etc. With EElink, just press a few buttons to easily manage the customer base or preventive maintenance. Even operations that were once complex become easier: for example, reconfiguring the control unit or the radio receiver in case of replacement or the setup of a control panel, starting from a standard or custom configuration.

24V

A precise, safe and reliable technology Bft 24V technology ensures optimum performance with a precise adjustment of slowdown in closing and opening. Safety is another key aspect, ensuring the immediate stopping and reversal of movement in the presence of obstacles. The efficiency of the technology is a guarantee of the product’s reliability.

Dynamic Path Tracking

The thrust required to operate safely. A smart torque management system based on the microprocessor technology of BFT control units. Acquiring data from several indicators, it updates the level of thrust required to perform the operation. D-Track also facilitates the installer in providing for the certifications required by law. Conventional control units do not “read” the exact position of the gate and consequently apply constant thrust levels, without ensuring stable sensitivity during the opening and closing operations. BFT control devices record the slightest variation in the gate or door force, for example due to differences in temperature or wear, constantly supplying the optimum torque to the motor. A conventional control unit could not detect these thrust variations, which would result in it indicating the presence of non-existent obstacles. The BFT system thus guarantees the maximum safety and perfect functioning of the equipment, no matter what the climactic and temperature conditions and degree of mechanical wear.

Practical applications of the underground hydraulic operator SUB BT

  • Luxury villas: An ideal automatic gate solution for premium residences, preserving the entrance’s aesthetics while ensuring safety and convenience for homeowners.
  • Hotels & resorts: Meets the requirements of frequent operation while creating a premium impression for guests.
  • Townhouses & special architectural projects: Suitable for limited spaces where maintaining the overall design is essential.
  • Agencies, offices, and high-end buildings: Ensures security and enhances a professional image.

Comparison with other underground gate operators

Compared with other underground swing gate operators such as the ELI BT A40 or standard electric motors:

  • SUB BT (hydraulic): More durable, smoother operation, higher load capacity, ideal for heavy gates or high-frequency use.
  • ELI BT A40 (electric): More affordable, easier to install, suitable for light-duty residential projects.

If you require a long-term, stable, aesthetic solution that is almost invisible after installation, the SUB BT is the optimal choice.
