At an airport there is a need to have Obstacle Free Zone (OFZ) of 200 ft on each side of runway so that during landing /take off Pilot can regain control or stop without obstruction. If sufficient free land is not available, frangible structures are permitted as these are very easily broken/destroyed/create a window or opening for the aircraft to travel through.

The frangible structures are able to survive to environmental loads encountered within the Airport Operating Area and at the same time offer little or no resistance to a stray aircraft. Low impact resistant structures are designed to withstand the static and operational / survival wind / Jet blast load with a suitable factor of safety, but, fail readily when subjected to the sudden collision forces of even a light aircraft travelling at say 75 knots.

The design of our Frangible Shelter are evaluated and certified by CADES, Bangalore, an ISO 9001: 2000, ISO/IEC 27001, AS9100 Company approved by Directorate General of Civil Aviation (DGCA) India, and Center for Military Airworthiness and Certification (CEMILAC) India.

Our frangible shelters are extra light FRP, prefabricated PUF insulated modular structures. The panels interlocking in these shelters are designed in such a way that if it is hit by an aircraft the shelter will collapse.

Purchased with an Aegis modular building is the ability to expand the shelter at a later date. Expansions are done with modular additions (in length) without interruption to online services and is accomplished within one to two days. This capacity provides obvious planning relief for growth.

When required, the client’s equipment installation can be incorporated at the Aegis’ building facility rather than on-site. Aegis accepts, warehouses, and insures the client’s equipment, which is then installed during the last phase or after the building assembly but prior to delivery. This service streamlines the build-out process, saving time and money.

Active Cooling Systems

Active air conditioning is a standard configuration for shelters, and it is the most efficient solution when the heat to be dissipated is high or when commercial power is available. The control of the internal temperature is achieved by using various solutions, which are selected according to the local environmental conditions, the internal thermal load, and the equipment temperature constraints. Aegis can provide shelters with several different active cooling systems:

• Heat Exchanger
• Air Conditioning Units
• Heaters (for low temperatures)

Passive Cooling Systems

Shelter operators around the world are now exploring the possibilities of passive cooling systems by using Phase Change Materials. By using this technology savings on power usage for conventional heating and cooling systems is achieved thus lowering the energy costs of the network. Aegis can provide complete design and implementation of passive cooling technology in its shelters

In addition to Alltec’s bus bars for grounding/earthing requirements, Aegis offers TerraDyne^® Electrolytic Grounding Systems (EGS). TerraDyne^® EGS is a multipurpose grounding/earthing system that has been designed to provide long term protection from lightning, electrical transients, static discharge, electro-magnetic interference, and other electrical hazards. The system has been designed for use in any type of soil condition. This system is commonly used in cellular, radio and television broadcasting sites, computer facilities, power substations, communication centers, medical facilities and industrial plants. It is stable grounding system that provides undisturbed long-term performance while maintaining cost efficiency.

Complimenting Alltec Corporation’s Electrolytic Grounding System is is TerraFill^®. TerraFill^® creates a reliable, low resistance, electrical connection between the grounding system and the earth. It is manufactured to be compatible with copper grounding systems and standard field application methods. It can be used in connection with grounding grids to minimize step and touch potentials. In high resistivity soils, TerraFill^® can be used to produce acceptable grounding impedance within a reasonable sized area. Manufactured from environmentally safe and stable products. TerraFill^® is self compacting, comes in easily transportable 50 lb (22.68 kg) bags, and can be easily installed by a single person.

Aegis lightning protection equipment is provided by Alltec Corporation and includes its patented dissipation terminals, TerraStat^®. TerraStat^® lightning protection terminals are designed to protect anything from the tallest broadcast towers to the smallest remote scada system, and almost any type of structure or facility in between. Aegis Building Technologies provides the TS-500 & TS-510 terminals especially for broadcast and communications towers, high mast lighting and other high-risk structures. Whatever your requirements, Aegis has a product to fit the application. For special applications, a custom design may be manufactured to fit the site requirements.

Proper grounding alone will not protect a facility from damage due to surges, transients, or lightning. An effective combination of lightning protection, facility grounding/earthing, equipment bonding, and properly installed transient voltage surge suppression (TVSS) devices, or surge protection devices (SPD), on all circuit conductors maximizes total site protection. Aegis Building Technologies comprehensive site protection approach rests on good grounding, protection from direct lightning strikes, and properly implemented surge protection. Aegis relies on Alltec Corporation’s PowerTrip^® devices to complete this strategy. PowerTrip^® devices are available for AC and DC power, telephone/ data, and RF cabling protection. Aegis provides technical assistance on selecting the appropriate TVSS for your application and the expert installation that is crucial to protection success.

A guyed, monopole, or self-supporting tower, constructed as a freestanding structure or in association with a building, other permanent structure or equipment, containing one or more antennas intended for transmitting or receiving television, AM/FM radio, digital, microwave, cellular, telephone, or similar forms of electronic communication.

Guyed Tower

• A communication tower that is supported, in whole or in part, by guy wires and ground anchors is a Guyed Tower.
• The substantial footprint of a guyed towers allows them to be constructed to substantial heights with greater loading than both Monopoles and Self Support towers (television towers), making them ideal for large microwave, broadcast and LMR applications.
• Guyed towers require components such as guy wires, thimbles, guy brackets, pier pins, anchor rods and turnbuckles.

Lattice Tower (Self supporting)

• A self-supporting three or four sided, open, steel frame structure used to support telecommunications equipment is a Lattice Tower.
• Lattice Towers are designed for PCS/Cellular and point-to-point communication and  have a larger footprint than Monopoles, their structural design often enables them to carry more wind loading at a lower cost than monopoles.
• These tower are normally constructed using hot dipped heavy duty galvanized steel.

Monopole Tower

• A communication tower consisting of a single pole, constructed without guy wires and ground anchors is a Monopole Tower. These towers are made of structural pipes & plates and are easily installed due to their precisely fitted connections. The connections allow each pole to be modified according to height and antenna configurations.
• Monopoles are an ideal solution for many broadband, microwave and cellular applications in urban and suburban areas where space is a premium and aesthetics are a must.
