Soltigua - Model PTMx - Parabolic Solar Collector
PTMx, Soltigua’s parabolic trough, is developed and produced in Italy. Due to several innovations, PTMx 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.
Product Details
PTMx 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;
- certification according to EN 12975.
Working Principles
The parabolic mirrors of PTMx solar troughs focus the sun rays on the receiving tube to heat the working fluid up to temperatures which are not reacheable by traditional solar collectors. During the day, thanks to an automatic system, the mirrors rotate around the main axis to track the sun, thus maximising the thermal gains. In case of bad weather and during night the mirrors close to the stowing position.
Design
A sustainable identity
Due to its modern design, PTMx is an architectural distinctive sign that characterises a building’s profile and communicates environmental awareness. The parabolic troughs therefore increase the value of the building by emphasising its sustainability.
Ideal installations include:
- shopping malls
- hospitals
- tourist and hotel resorts
- office buildings
- district heating and/or district cooling systems
- industrial sites in various sectors
- (food and beverage, textile, industrial cleaning, etc.)
Sustainability
By delivering thermal energy up to 250°C PTM expands the field of application of highly sustainable solar thermal energy to an entire set of new applications, which include industrial process heat and solar cooling.
PTM creates new opportunities to move towards a more sustainable society and its high performance provides not only sound economic ground for industrial and civil investment, but also boosts the environmental impact of its applications.
One PTM 24 operating at 150°C can reduce CO2 emissions like a forest of over 400 trees.
Technical Features
PTMx is available in four basic models of different size, that can be combined in order to realize customized solar fields, starting from few hundred square meters of collecting surface.
Installation
PTM-x can be used in both new and existing buildings to complement traditional energy sources. The parabolic troughs can be installed, in accordance to the relevant regulations, on flat roofs or on top of parking slot shelters. They can also be organised to create solar fields on ground.
Thanks to its special characteristics, PTMx functions also in rigid climates, representing an optimal solution for residential, commercial and industrial buildings.
