Soltigua - Model FTM - Linear Solar Thermal Concentrating System
Soltigua’s Fresnel collector FLT is a linear concentrating system for generating heat in the range of 100 KW to several MW at temperatures up to 320°C. Developed and produced in Italy, FLT offers all the advantages of solar thermal concentration so far available only to large solar thermal power stations. FLT’s light structure, compact dimensions and innovative design make it an ideal rooftop solution for industrial process heat, solar cooling and polygeneration applications.
Product Details

- Weather resistant highly reflective polished aluminium mirrors
- Selectively coated stainless steel receiver tube
- Highly accurate automatic sun tracking with multimirror drive
- Sensors to measure: angular position, fluid temperature, wind speed
- Controlling PLC with web based remote monitoring
- Stowing procedure in case of bad weather
- Safety procedure against high wind, overheating and lack of flow
- Hot-dip galvanized metal structure
- Electric panel at 230V

FLT is a linear Fresnel collector which concentrates the sun rays by focusing the solar radiation reflected by several primary mirrors on a single receiver tube.
After the reflection of the primary mirrors, part of the sun rays hit the receiver directly, while another part of them are reflected a second time by a secondary mirror of complex shape which enables them to deliver their energy to the working fluid contained in the receiver tube.
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
Innovative design in every detail
The innovative technical content of FTM translates seamlessly in a highly attractive design which combines low visual impact and the beauty of essential geometrical lines.
Attention to the aesthetic impact is well documented also in the choice of every detail, such as the modular design of the mirrors and of the receiver tube, where each component satisfies the functional needs of the solar collector while also enhancing its architectural profile.
Sustainability
By delivering thermal energy up to 320°C FLT 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.
FLT 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 FLT10v-72 operating at 150°C can reduce CO2 emissions like a forest of more than 1’500 trees.
Technical Features
FTM is available in 4 basic models that can be combined in order to realize customized solar fields ranging from 67 to several thousands square meters of collecting surface.

FLT can be used in both new and existing buildings to complement traditional energy sources. The linear Fresnel 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, FLT functions also in rigid climates, representing an optimal solution for residential, commercial and industrial buildings.
