Heat Transfer Fluid for Concentrated Solar Power and Thermal Storage Applications

Concentrated Solar Power (CSP) plants require the use of a specific heat transfer fluid that is designed to work to the correct temperature for prolonged periods in solar thermal electricity applications. Global Heat Transfer are experts in helping CSP and solar thermal electricity engineers monitor and maintain heat transfer fluid for optimum operating efficiency in thermal storage.

Heat transfer fluids are utilised in CSP or solar energy generation and solar thermal storage, using concentrators such as parabolic trough-based systems. CSP technology uses mirrors (predominantly parabolic mirrors) to reflect and concentrate sunlight which converts to heat. Globaltherm® Heat Transfer Fluids, Omnitech and Omnipure, are used to collect the heat energy and transport it to a power station for thermal storage as a renewable energy technology.

Globaltherm® products provide the high temperature stability necessary to avoid fluid degradation at high operating temperatures. Degradation can reduce overall fluid life and reduce system heat transfer efficiency and safety and can increase maintenance expense.

Global Heat Transfer is a key supplier supporting the rapid growth of CSP renewable energy technology and solar thermal electricity worldwide. We have the production capacity to deliver the high volumes of thermal fluid required for CSP thermal electricity installations, within tight timeframes to remote locations.
