COMPLETING THE PRODUCTION RANGE

SITAL production includes several types of other products; the following list gives a quick overview of their main features.

“Big Engine” enclosures

They are demountable enclosures engineered for an indoor installation and suitable for gen-sets of big dimensions.

In their standard configuration they guarantee a residual noise level of 85 dB(A) at 1 m measured inside the room.

The “big engine” enclosures have large side doors, allowing an easy access to the equipment installed for ordinary maintenance.

The openings for air inlet / outlet of cooling air are acoustically protected by soundproofing baffles and equipped with fixed-blade louver and bird mesh.

Exhaust gas silencers are mounted on the enclosure roof; they are sized according to the residual noise level to be achieved.

Epoxy primer and polyurethane paint are used in the standard painting cycle, suitable for indoor installations. Other cycles are available on request.

SITAL “High Performance” super sound-attenuated enclosures for gen-sets up to 250 kVA

SHP are monolithic enclosures for indoor and outdoor installations, suitable to reach a residual noise level of 55 dB(A) measured at 7 m in free field.

They are used for gen-sets rated up to 250 kVA.

SHP enclosures have a drop-over installation: the enclosure rests on the enclosure base, fittingly built, and to which it gets bolted.

The base is built by the Customer following the instructions given by our Technical dept., or it can be optionally included in SITAL supply.

The painting cycle changes according to the environment and climate of the site of installation.

Demountable enclosures for power plants

These enclosures are especially engineered to reach high levels of acoustic dampening on stationary big equipment, where frequent maintenance is required.

Special features are:

1. Enclosure of any size and shape, that can be built thanks to modular panels
2. High acoustic dampening, achieved using extra technical devices besides panels insulation
3. Easy maintenance, thanks to panels that can be demounted by removing only a few bolts (a small hoist can be supplied inside the enclosure)

Two versions are available:

• For indoor use
  The structure of these enclosures is made of a supporting frame and a series of soundproofing panels, fixed to the structure using brackets or by interlocking. With this configuration the external steel sheet is smooth and it can supplied either in galvanized or painted version.
• For outdoor use
  Similar to the indoor version, the structure of this enclosure is made of self-supporting soundproofing panels. However, the external surface is made of corrugated steel sheet and it can be painted according to the best painting cycle that suits the environment of installation

The soundproofing level is studied each time according to the Customer’s request, to the installation environment and to the noise source.

The quantity, dimensions and features of technical passages provided depend on the requirements of the equipment to be installed inside the enclosures.

These enclosures are particularly suitable for soundproofing power plants with big gen-sets, but they can also be used for different applications, such as soundproofing machines for wood industry, testing rooms, etc.

Soundproofing rooms within buildings

SITAL studies and installs soundproofing of gen-sets installed inside rooms with concrete walls.
Soundproofing is made using:

• sound-dampening baffles applied on the openings for air inlet/outlet of the room
• exhaust gas silencers mounted in suitable position and to be conveyed in the room chimney
• auxiliary ventilation system, if necessary
• sand and dust filtration systems (on request)

The soundproofing baffles and the exhaust gas silencers are always sized according to:

• radiator cooling air flow or cooling requirements, if the radiator is installed outside the room
• exhaust gas flow
• residual noise level to be achieved

Soundproofing of industrial vehicles

SITAL production includes also the engineering and soundproofing of noisy parts of industrial vehicles, such as trucks, trains, vans, etc., and also special equipment such as tractors, excavators, etc.

Our personnel will be available for an inspection, measuring the noise on the parts that need sound-attenuation; the following steps will be:

• a preliminary feasibility study
• economic offer
• engineering
• building and painting of the parts for the executive project
• mounting on site
• final test

On request, the same steps are followed to soundproof the noisy parts of stationary industrial machines.

Fuel tanks

On request, SITAL manufactures the fuel tanks, that are going to be installed inside its own containers and enclosures.

Fuel tanks manufactured by SITAL are usually vertical, with square base. They are sized in order to fit them inside the available spaces of the containers and enclosures.

Single-skin and double-skin fuel tanks are available.

All technical passages are provided, while accessories (level gauges, valves, pumps, etc.) are supplied only upon Customer’s request.

On request, fuel tanks for outdoor installation are provided.
