RIELLO SC SUN 300

The 

SC SUN 300

 is a separation module incorporating a plate heat exchanger used in systems where energy is supplied 

to two hot water buffer storage cylinders – or at two different heights to a single buffer cylinder – by a solar heating system 

equipped with arrays of collectors. The electronic control system governs the revolutions (0-10 V speed control function) 

of the high efficiency pumps on the primary and secondary circuits so as to ensure optimum exploitation and manage-

ment of the energy produced. The controller is also designed to allow remote control of the system by way of an Ethernet 

port, save system-related operating data to an SD card, and report any irregular or abnormal events that may occur. 

The primary circuit is equipped with an electronic flow meter (Vortex flow sensor) displaying the flow rate and allowing 

computation of the amount of heat exchanged.
