Generally, the environmental monitoring and control units adopt AC power supply. When AC power has been cut off, the DC 48V battery group can also supply the power.
Automatic Ventilation System
The automatic ventilation system is capable of inducting the outdoor air into the shelter when the outdoor temperature is lower so as to decrease the room temperature, shorten the working time of the air conditioner and thus to effectively save the power consumption of the base station. Meanwhile, the automatic ventilation system starts to work when the utilized power is off or there is failure on air conditioners, and thus to prevent the occurrence of failures caused by overheat temperature inside the room.
The automatic ventilation system consists of the air in drafting device, air exhaust device, smart controller, humidity & temperature sensor, waterproof housing, air filtration device and other accessories for installation. Users can select ventilation system of different specification according to the equipment room’s size and equipments’ heat radiation volume.
Standard specification: SYT-08, SYT-16, SYT-2416, SYT-24
Air Indrafting Device of SYT-24 Automatic Ventilation System
Fence
The special hot-dip galvanized sectional railings are capable of preventing from rust for 15 years. The stainless steel burglarproof set screws are used to secure the railings to form a fence which has a distance of 50mm from the ground and with the sharp heads as well as the spined wire nettings on the top so as to effectively prevent unauthorized access.
The water and clay can be reduced by friction between the shoe sole and metal grids on the stairs and the clay can be further substantially eliminated via the upper coir mat and thus to keep the shelter clean inside.
Steel Stairs
Air Conditioner Shield
Protect the outdoor part of the air conditioner from being stolen.
Cabling Rack
The communication cabling rack is an indispensable accessory in modern communication shelter. In addition to load all of the cables, provable cabling and the top fixed points for equipments, it also has the function of beautifying the shelter appearance. The cabling rack can be classified into two types in terms of its materials: steel panel cabling rack and aluminum cabling rack. And it can also be divided into the supporting type and lift-installing type according to the mounting method.
Supporting Cabling Rack
Lift-installing Cabling Rack
Three specifications of regular width are available for the mobile base station cabling rack: 150mm/300mm/500mm，and the special width specifications can be made for actual requirements. The length is determined by the size of the shelter, and multiple racks can be combined while the shelter is with large length.
Aluminum Alloy Ladder Used for Repair & Maintenance
It is used for ease of the repair & maintenance of the equipments which are installed at high position in the shelter.
Aluminum Alloy Ladder
The cable entry is mainly used for waterproof sealing treatment for the cables before they are fed into the shelter. It is featured with good sealing performance, easy installation, etc. the can be installed conveniently.
There are two types of cable entry: gum ring and aluminum sheet.
The general specifications of the cable entry include the six-hole, eight-hole, nine-hole, etc.
