SOLAR PROCESS HEAT
A vast number of industrial processes that require thermal energy can be realised by integrating traditional energy sources with solar energy. In sectors where medium temperature heat is required concentrating and tracking 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 (e.g. enhanced oil recovery), or where peaks of demand are reached during summer (e.g.: beverage industry).

Further Solar Thermal Applications
SOLAR THERMAL POWER
Soltigua’s concentrating collectors can be used to generate power in combination with thermal power blocks such as ORCs (Organic Rankine Cycle) or steam turbines.
SOLAR COOLING
Solar cooling is one of the most fascinating applications of solar energy, because it generates air-conditioning directly from the sun.
