ISO-BOX
The carpentry is made of panels and steel sheet sections, with thickness 15/10, hot-dipped galvanized according to the rules UNI 5753-75, which ensure a perfect zinc anchoring on steel (200 gr/mq) and pre-painted on the exposed side, according to the system Magona 3000/80, with high stability pigments after the phosphating process and a layer of primer apply on both sides, in oder to have a dry film protection with thickness 25±3 microns on the exposed surface and 3 microns on the not exposed one, of white and red color.The assembly of the various units (floor, covering, buffer walls, etc.) is made exclusively by using screws, bolts and riveting of high tensile steel and joined with angulars in non-ferrous material. This solution, besides the extreme solidity of the assem-bly, ensures that any oxidation point is not formed.Roof, floor and vertical panel walls are designed to carry non-recurrent loads (snow, ice, wind) and operating loads (equi-pment, systems and people) according to the requirements of the technical specifications and existing law.The insulation of the roof and of the vertical walls are guaranteed by the interposition of sandwich panels, with thickness of 30 mm , made of pre-painted steel and polyurethane foam joined by adhesive at the inside.
Structure description of the outdoor cabin
The vertical walls of the cabin are realized with prefabricated panels, made of zinced steel sheets and pre-painted with a thickness of 1.5 mm. The closing panels are able to accomplish the structural lifting and closing functions, and guarantee:
• high compactness of the walls;• water-proof;• wind resistance ;• impact strength;
• weather-proof;• transport resistance;• resistance to breaking through.
Vertical panel walls
The cabin covering is realized with panels of press-formed steel sheets, with interposing of insulation layer, characterized by a structure with specific ribs to obtain a suitable carrying and water-proof capacity. The external surfaces of the cabin covering panels are well-finished, the carrying capacity of the roof is suitable for the fixing of the cable channels and eventual lighting systems or other limited weight equipment (~ 60 kg).
Covering
The cabin floor is realized by a series of overlapped structures in order to ensure the best carrying, comfort and duration of time conditions. Consequently the floor is made up a series of corrugated steel sheets placed side by side with a thickness of 2 mm or in any case adequate to the design loads and coated by suitable insulating mat.
Floor
15
The access to the cabin is made possible through a door positioned on the frontal side for the entrance to the operator closet. The door is realized with press-formed steel sheets to assure suitable compactness and non-deformability. The hinges are of the not removable type from the outside .The thickness of the access door is adequate to the thickness of the cabin walls and is equipped with a suitable blocking system by opening through compass fitting, in order to avoid casual closings due for instance to gusts of wind. The lock will be of antipanic 3 spongings type, with safety key that allows the opening from the inside, through shackle, even if the lock is closed from the outside
Doors
The thermal cabin isolation is ensured by sandwich type panels with internal isolating material composed of expansive polyurethane resins, at an average density of 40 kg/m3 toll. +/- 10%. The thickness, the thermal acoustic insulation features and the panel surfaces are suitable to guarantee self-supporting,insulation, water tightness, leak tightness and resistance, especially in the joints, and are a pleasant aesthetic solution, both for the outside and for the inside. All the panels are able to preserve in the course of time their flatness and their physi-cal-mechanic features, without material deterioration nor adhesion loss between material and containment surfaces.
Thermal acoustic insulation
16
All the surfaces of the steel elements are designed for both external and internal use, of smooth type or variously confor-med, will be protected against the corrosion phenomena with proper treatment processes accordingly to their particu-lar exposure condition. The fixing elements will generally be of stainless steel type, galvanized passivated, chromed or in any case treated against corrosion before the use in the cabin. For the metal panels there will be preferably chosen pre-painted steel sheets realized with methods and features depending on the used thicknesses and the installation (outside or inside). The manufacturer will provide the technico-chromatic specifications for any little additional touches. For the steel sheets with a thickness superior than 3÷3.5 mm, for the materials expected elsewhere and on explicit custo-mer’s demand, as well as for eventual small surfaces of press-formed or section steel sheets, there will be executed “spray” painting on sandblasted base and/or however suitably prepared by adequate primer treatment.
Rust-inhibitive protection of the constructive elements against atmospheric agents
A conditioning system can be foreseen in order to make the working environment healthy and confortable. Theproposed conditioner allows the temperature control (cooling), the maintenance of the relative moisture (between40% and 60%) and for the upkeep of the air cleanness from dusts and/or pollens. This system is of monosplit type andin the main has a low noisiness according to the anti-noise pollution rules.
Air conditioning system
The distribution is foreseen in low voltage LV with the following features:
• Feeding:single-phase system 230Vnet frequency: 50 Hz
• Distribution:Single-phase system 230Vnet frequency: 50 Hz
• Ambient temperature:External -10 °C ÷ +50 °CAverage internal variable from +22 °C up to +27 °C

The system is provided with a suitable lighting system to give comfort during the stay in the surroundings, to guaranteesafety in the technical zones, to allow the maintenance of the equipment and the specific activities of thesystem itself. The internal lighting system will be carried out with fluorescent lamps properly placed and sized.
Lighting system
By earthing system we mean a group of ground electrodes, earthing conductors, earthing collectors, protectionand equipotential bending conductors designed to realize the grounding of protection and /or correct operation.The system is made up of the following elements:Ground electrode is composed of the group of dispersing elements that can be:
• Mechanical strength in order to be able to resist against the solicitations during installing operations and against those due to land settling;• Good continuity of the electrical connections between several elements that constitute the ground electrode;• Resistance against chemical aggression of the land.
Earthing conductor: it connects the dispersing system to the earthing collector and the ground electrodes among themsel-ves; if it is bare and buried it has the same function of a ground electrode. In case it is isolated and placed in a heavy PVC protection pipe, it must have the same features of the protection conductor; in absence of protection pipe the minimum section must be of 16mm2; the table indicates the minimum sections of the earth conductors.
• Ground electrodes of fact constituted from the irons of the foundations in reinforced concrete (beams, plinths, continuous beams, pillars, posts, etc.); the metallic shirts of the pools can be used too, but not the pipelines of the public aqueduct.• Intentional ground electrodes constituted by metallic bodies in direct contact with the land, which stakes, ropes or tapes of suitable dimensions, which scope is to guarantee the necessary resistance against corrosion and mechanical stress (the sump is not required).
In general about earthing system
The requirements for the ground electrodes are the following:
