COMPONENTS FOR SOLAR THERMAL SYSTEMS

COMPONENTS FOR SOLAR THERMAL SYSTEMS

The Caleffi Solar product range has been specially developed for use in solar thermal systems, where high temperatures can normally be reached and where, depending on the kind of system, there can be glycol. Materials and performance of the components must necessarily take into account these particular operating conditions. COMPONENTS FOR PRIMARY CIRCUITS Automatic filling
