FUNCTION
Series S001 and S002 circulation units
are applied to the primary circuit of
solar systems and oversee management
of the solar panel - storage tank fluid
thermodynamic cycle for subsequent
supply to utilities via hydraulic
distribution circuits.
They consist essentially of a circulator
with appropriate performance (rate of
flow/head) and regulation and control
devices governing the operating circuit.
