Clean energy production, greenhouse gas emissions reduction and environment preservation: Soltigua

creates new opportunities for the commercial and industrial sectors in terms of sustainability. Soltigua

offers solar-based innovative solutions to respond to the modern requirements of air-conditioning and

industrial heat production.

The parabolic solar troughs produced by Soltigua are the core of these energy systems; they are solar

thermal collectors which track the sun and concentrate its rays, enabling the system to reach high ope-

rating temperatures (above 200C). Hence, solar energy can be used in areas previously considered not

suitable for renewable energies.

Soltiguas solar concentrating systems can adapt to all requirements, from HVAC systems for small buil-

dings to large solar fields for industrial use.

Due to their distinctive design, Soltiguas solar troughs clearly mark the sustainable profile of a building.

PTM, Soltiguas parabolic trough, is developed and produced in Italy. Due to several innovations, PTM

includes all the advantages of solar concentration that, up to today, have been available exclusively to

solar thermal power stations.

Today, this innovative technology becomes available for a wide range of applications.

PTM is available in three basic models of different size, that can be combined in order to realize customi-

zed solar fields, up to several hundred square meters of collecting surface.

PTM parabolic collectors include the following innovations:

- high modularity, available also in small sizes;

- multiple possibilities of installation, such as, for example, on flat roofs;

- modern and attractive design;

- unbreakable mirrors;

- precise and reliable sun tracking system;

- automatic safety devices;

- possibility of installation along any orientation.

1The above-listed energy data of the parabolic troughs are purely indicative, since they are based on preliminary experimental results.The efficiency of the solar concentrators could vary depending on the installations location and orientation, climatic conditions, plantdesign adopted and the fossil fuel which is being substituted.

Due to its modern design, PTM is an architectural distinctive sign that characterises a buildings profile

and communicates environmental awareness. The parabolic troughs therefore increase the value of the

building by emphasising its sustainability.

PTM can be used in both new and existing buildings to complement traditional energy sources. The pa-

rabolic troughs can be installed on flat roofs or on top of parking slot shelters. They can also be organised

to create solar fields on ground2. Thanks to its special characteristics, PTM functions also in rigid climates,

representing an optimal solution for residential, commercial and industrial buildings.

Solar cooling is one of the most fascinating applications of solar energy, because it generates air-con-

ditioning from the suns energy. This system takes advantage of the coincidence of high summer solar

radiation and the need for air-conditioning during the same period. , This reduces significantly the energy

consumption of the building, thus increasing its environmental sustainability. In particular, solar cooling

decreases electricity consumption during peak hours and therefore reduces the risk of blackouts due to

grid overload. A source of traditional heating and a storage system enable continuous operations at night

or during cloudy periods.

PTM solar concentrators represent a revolutionary technology because they achieve a high efficiency of

the cooling system by supplying a double effect absorption chiller with high temperature heat. Unique

in its kind, this solution permits the maximum exploitation of the suns potential, generating an energy

efficiency which can not be reached by other solar technologies.

PTM can be efficiently used to integrate domestic hot water production and to contribute to a buildings

heating during winter, offering a complete solution for HVAC systems that reduces emissions and the

energy bill. Due to its characteristics, PTM can also function in combination with medium-temperature-

heating-systems , such as, for example, those with radiators.

Furthermore, by using clean and renewable solar energy, parabolic troughs represent the most appro-

priate technology for realising solar district heating and cooling systems.

Thanks to the abundant solar radiation available throughout Southern Europe and the Mediterra-

nean area, a vast number of industrial processes that require thermal energy can be realised by in-

tegrating traditional energy sources with solar energy. In sectors where medium temperature heat

is required PTM collectors can be used to generate process heat. Energy savings and environmental

pollution reduction are particularly efficient in processes where daily and annual demands for heat

are constant, or where peaks of demand are reached during summer (e.g.: dry-cleaning facilities for

tourist resorts).

PTM parabolic troughs can be efficiently used to realise:

- seawater desalination plants;

- industrial refrigeration at temperatures below 0C;

- localised power station plants.
