Insulated containers

These containers are built to house and soundproof electrical cabinets, UPS, transformers, conversion systems for PV plants and any other industrial equipment for which an installation in a thermal insulated weather-proof environment is required.
They have building features similar to shipping containers (upper and lower corner castings, monolithic structure, walls and roof made of corrugated steel sheet), making them suitable for road and railway transportation, vessel and air freight .
Dimensions
The containers can be built with dimensions complying with ISO 668 regulations (codifying dimensions of standard shipping containers) or they can have special dimensions, according to the size of the equipment to be installed or complying with Customer’s specifications.
CSC certification
On request, 20ft, 30ft and 40ft containers can be supplied with CSC certificate, making them accepted and handled by forwarders as containers. Without the CSC certificate, forwarders handle the containers as boxes, raising prices consequently.
If CSC certification is requested for containers having dimensions different than what mentioned before, the evaluation will be carried out for the single project.
Type
SITAL manufactures these containers according to two different building methods:
- Container TYPE 1 (max. strength)
They are called “double skin” containers; they are made of external corrugated steel sheet and they are thermally insulated with industrial “sandwich” panels made of rock wool or expanded polyurethane and clad with pre-painted galvanized steel sheet. They are the best solution for installations requiring a high structural solidity. - Container TYPE 2 (light version)
Side walls are made of adjoined industrial “sandwich” panels, which are demountable one by one. TYPE 2 differs from TYPE 1 because corrugated steel sheet is not used, leaving the panels visible from outside. Exception is made for the roof, which is actually made of corrugated steel sheet in order to prevent rain infiltration. However, water-tightness is guaranteed through time for the whole container.

Optional versions
- Adjoined containers
When max. internal space is required, two or more containers can be adjoined by removing a wall or part of it. In this way much bigger enclosures can be obtained starting from modules with standard dimensions or with smaller dimensions, anyway. - Drop-over container
Here the base is separated from the rest of the container (roof and side walls), to which it gets bolted. This option is chosen for an easier installation of all the equipment directly on the base, using all the space needed in order to complete the installation in the easiest way possible, without the obstacle of walls and roof.
The base supply is optional. Customer’s base can be used provided that it has fixing points for the connection of the container to the base; alternatively, SITAL can engineer and supply a suitable base according to the Customer’s requests.
Feasibility study and internal/external layout
Both the internal and external configuration of the container are studied each time according to Customer’s needs. Upon issuing the quotation, SITAL already produces a feasibility study with a preliminary drawing based on Customer’s information and data, outlining the following elements:
- position of the equipment inside the container
- quantity and position of doors
- dimensions and position of openings for air inlet/outlet
- dimensions and position of internal separating walls, used to create separate rooms for electrical cabinets and other accessories.
Painting
Painting is one of the strongest points in SITAL production process. The company owns automatic plants for both sandblasting and painting. A wide range of painting cycles are available, for example:
- Five standard cycles, according to the environment where the container is installed
- Special painting cycle for offshore environment using Carboline products
- Polychromatic cycles for military containers
- Special painting cycles made according to Customer’s specifications
Technical passages
All technical passages are sized and protected according to the specific needs of the Customer. Our supply includes:
- Sleeves for the passage of fuel pipes or cooling water pipes
- Niches for sleeves of fuel feeding, emergency stop push button, firefighting central unit, air-conditioning external unit, etc.
- Cable entry/exit protected by aluminum plates to be drilled on site, or by MCT (optional)
Systems and accessories
Thanks to the wide range of services available, SITAL supply is not limited to the container, but, on request, it can include any system and accessory, up to the delivery of the complete package.
Packing and preparation for shipment
If necessary, SITAL supply includes also the packing of the container
