For use in closed loop design only. The
solar station is used on the primary loop of
solar thermal systems to control the
temperature in the hot water storage tank.
This station contains the functional and
safety devices for optimum circuit control.
The components enable:
 Solar fluid circulation with solar pump
 Safety against pressure increase
 Exact flow rate control
 Flushing, filling and draining the circuit
 Measuring the supply and return
temperatures
 Deaerating the solar loop
 Shutting off the circuits
 Preventing gravity circulation
 Thermal insulation of the components
