Variel, a. s.

Technological containers GSM

Variel engineering containers are mainly designated for installing telecommunications, monitoring, navigational, media, security and other technical equipment, and protect against inclement weather conditions, damage, theft or handling by an unauthorised person. The materials used to manufacture the container ensure product durability while keeping maintenance at a minimum.

The use of engineering containers is ideal everywhere where, for technical or economic reasons, it is necessary to find an operative solution for quickly making installed equipment operational (for example, this significantly simplifies the building permit process). It is absolutely necessary to use containers in situations where a future need to relocate the technology can be foreseen. The sturdy and robust construction of Variel engineering containers make relocation possible without having to incur the high costs of disassembling the installed technology.

The estimated lifetime of Variel containers is at least 30 years.

STANDARD DESIGN OF ENGINEERING CONTAINERS

The construction of Variel containers complies with current environmental demands and all parts have been designed in accordance with legal norms and the relevant safety, hygiene and fire prevention regulations.

The supporting construction of the container is comprised of a shiny, galvanised bent steel section weldment. It is made up of a supporting bottom frame and a top frame. The frames are connected with vertical thin-wall section ridges.

The floor of the container is a reinforced supporting steel construction. On the outside it is in a galvanised steel shell, and from the inside it is made up of water-resistant plywood and a PVC floor covering. The thermal insulation on the floor is comprised of mineral felt.

The inside and outside walls are covered with galvanised steel sheet and painted the client’s desired shade. Thermal insulation is provided by 80 mm-wide mineral felt; the standard heat insulation value is k = 0.5 W/m2K. Brackets for holding technology can be added to the inner walls.

The ceiling is made up of 80 mm thick insulation panels. The panels are installed in the upper frame to create the exposed side of the ceiling.

The roof is monolithic, made of 4 mm wide fibreglass. This design is practically maintenance-free. The maximum load bearing capacity is 150 kg/m2. The doors are steel, insulated, fireproof, with an option to have three-point closing installed. The doors are secured against unhinging.

Electrical installation. Electricity is distributed using CYKY cables stored in cable channels. The container is connected to the distribution network at the destination site via a fixed main that runs through the container floor. Individual power circuit protection is installed in the circuit breaker distributor.

Protection against the effects of static and atmospheric electricity is secured in compliance with ČSN 34 1390 art. 20. The electrical installation can be changed at the client’s wish based on the technology used in the container.

Accessories can be delivered independently or be included in the container order.

Accessories are:

Protective shiny galvanised steel walkway beams;
Supports under the container (height 250 mm – entry step can be connected);
Supports under the container (height 400 mm – universal steps can be connected);
Entry step (for a container set 250 mm above ground level);
Entry steps – two steps (for a container set 400 mm above ground level);
Universal steps with a landing (for a container set 400 mm above ground level); three options – direct, left and right;
Container covered with wood panelling and topped with a ridge roof (for use in places where the container needs to naturally fit in with the natural surroundings).

ADAPTATIONS

Upon the client’s request, the containers can be adapted by making not just minor, but also major exterior adaptations to the construction.

For example:

Atypical container dimensions;
Separated space for users, with individual entries and separate or common electrical installations, air conditioning etc;
Container construction, shell made from stainless metal (for extreme environments);
Exterior shell made of aluminium sheet or wooden beams;
Galvanised or stainless roof;
Ridge roof with roofing tiles or shingles;
Change to the thermal insulation characteristics of the container.

OPTIONAL EQUIPMENT

Various optional equipment can be added to the basic version of the container.

Examples:

At the client’s request, the basic electrical installation can be augmented or changed according to the needs of the technology installed. After agreeing with the client, it is possible to install parts or individual units of the client’s own technology.
To maintain ideal operation conditions for the installed technology, the containers are usually also equipped with air conditioners and space heating panels.
If needed, the containers can also be equipped with security systems, feeders, emergency power generators etc.
The interior equipment is always designed individually, according to the client’s wishes (such as battery frames, cable organiser panels etc). Special-purpose containers can also feature anti-static floors.
A protective grate can protect the laminate roof against damage (e.g. from ice falling from the antenna). In addition, grating that serves in anchoring antenna systems can also be delivered.
In case of special needs, the container surface can be finished with artificial plaster, wood panelling, the container can be topped with a ridged roof etc. so that the appearance of the container disturbs the surroundings where it is installed as little as possible.
The container delivery can also include six to 12 meter antenna poles, including holders to attach the pole to the side of the container.

BASIC SERIES

The containers are manufactured in several size options and with a number of special adaptations. Each type is based on the same construction base but is adapted as much as possible to clients’ individual wishes. Normally a new container type featuring a number of partial adaptations is created for each new client. The containers are manufactured in various lengths, with standard widths of 2436 mm and heights of 3120 mm. The container lengths normally used are 3.4 and 6 meters (containers with non-standard dimensions can also be manufactured according to the client’s wishes).

PARTIALLY ASSEMBLED CONTAINERS

Partially assembled containers are a special type of engineering container. These containers make it possible to place the technology on the top floors and roofs of high-rise buildings. The disassembled containers are delivered to the site in pieces, and assembly is carried out at the location. The reduced weight of the containers makes it possible to place them on foundations that have a low load bearing capacity. The partially-assembled containers are constructed out of a bottom-divided steel frame, corner vertical ridges and ceiling supports which are assembled on the steel frame on site. The floor is made up of 80 mm thick insulation panels, water-resistant plywood and PVC floor covering. The shell consists of 80 mm thick insulation panels. The divided fibreglass roof is screwed onto the top frame. The roof seams are sealed and cemented. The roof is made of 80 mm thick ceiling panels. A fireproof steel door measuring 800 mm x 1,900 mm is built into the front wall of the container. A covered ventilation opening is installed in the door. The total dimensions of the container can be altered based on the client’s wishes.

Partially assembled containers are manufactured in the same dimensions as fully assembled (fixed) containers and can be equipped with the same accessories and above-standard equipment.

CONTAINER MANIPULATION AND INSTALLATION

The container can be installed on a firm surface (concrete, reinforced concrete panels etc.) or on concrete stumps or strips built in accordance with the corresponding documentation. The containers are moved using a fork lift or crane with enough lifting capacity, with the attachment points on the bottom frame of the container and handling strips acting as guides.
