FLT
THE IDEAL SOLUTION FOR COOLING AND PROCESS HEAT.

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.

Its light structure, compact dimensions and innovative design make it an ideal rooftop solution.

In ground installations, it minimizes the use of land and the cost of site works for foundations and pipes.

Its high temperature range is well suited for many industrial process heat, solar cooling and power generation applications.
The main innovations of Soltigua’s FLT collectors include:
– 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
