Shielding & Gates

RF-Shielding & Steel Structure

The RF-shielding is Frankonia’s basic system and follows the principles of the Faraday cage. The modular and prefabricated high-quality RF-shielding is typically a pan-type shielding made of 2,0 mm galvanized steel that is manufactured to perfection. Frankonia’s shielding is used for all kinds of chambers and shielded rooms, such as control rooms, amplifier rooms, or any other room that requires a shielded standard.

> Hot-galvanized 2,0 mm thick steel

> Dismountable, nothing is glued or welded

> Self-supporting construction along with industrial design standards

> High-class and identical shielding attenuation for modules, doors, gates and all accessories

Steel Structure

For static purposes, larger chambers require an additional steel structure support that perfectly meets the shielding fixation, considers a variable static design for different chamber sizes and configurations, and adapts to any specific building characteristics and A/C layouts. Frankonia’s steel structure is a totally self-supporting system and does not require a connection to the existing building. Furthermore, for corrosion prevention the steel structure is coated by default akin to RAL 3020 with a guarantee of 10 years. Moreover, Frankonia’s steel structure considers country-specific seismic conditions as well as low point loading to the concrete slab of the building.

Doors & Gates

The doors and gates by Frankonia are designed according to industrial standards in respect of durability, flexibility and all kinds of safety issues related to the EC machinery directive. The triple-row knife-edge system achieves the same shielding effectiveness as the standard shielding modules by its innovative design, and therefore offers continuous quality. This special development allows for complex double-pivoted hinges that stabilize the construction and greatly extend the lifespan of the highly conductive contact springs. Furthermore, this system reduces the maintenance intervals to a minimum, ensuring a stable shielding performance.ically a pan-type shielding made of 2,0 mm galvanized steel that is manufactured to perfection. Frankonia’s shielding is used for all kinds of chambers and shielded rooms, such as control rooms, amplifier rooms, or any other room that requires a shielded standard.

General characteristics

> Very strong construction for long-lasting stability

> RF-shielding realized with an innovative triple row of highly conductive contact springs

> The complete triple-row knife-edge system is easily exchangeable

> Threshold protection considered to avoid damage

> Materials are hot-galvanized for corrosion prevention

> All materials used are equal to the shielding to ensure continuous quality

> Clever and easy to maintain

> Designed for MTBF 20.000 cycles without failure

> Door frame and leaf finish color in RAL 9002

Range of Doors and Gates

> Single-leaf door (SLD)

> Double-leaf door (DLD)

> Sliding door (SSD)

> Sliding gate (SG)

All gates are available as automatic version without limitation in size, which meet all kinds of EUT and customer-specific requirements. Any version of the door or gate is perfectly integrated in the shielding and respects the lining of the wall absorbers.

A great advantage of Frankonia’s sliding gates is the fact that all types of pyramid and hybrid absorbers, up to a length of 2,4 m, can be directly installed on the door leaf. Considering the EC machinery directive for safety issues to ensure a user-friendly and safe movement, audio and visible signals turn automatically on while moving.

> Triple-row knife-edge system of highly conductive contact springs

> Variety of doors and gates in combination with ramps and sliding or lifting platforms

> Manual, electric or pneumatic powered latching system

> Motorized movement for sliding doors and gates

> Perfectly integrated in the shielding and absorber lining

> Designed and built for long-lasting performance and stability

> User-friendly and safe use according to EC machinery directive

Features

Lifting Platforms & Ramps

In addition to all doors and gates, lifting ramps and lifting platforms are available, with either manual or automatic movements. The lifting platform is used in case the chamber is installed in a pit and provides a flat access level. The lifting ramp is used in case the chamber is installed on the finished floor or is partially installed in a pit and provides a smooth ramp access level. A sliding platform completes Frankonia’s range of EUT and personal access solutions. As a specialist in customer-specific requirements, there are almost no limitations in weight and size.
