Solar Collector Overheat Prevention | phcppros
This does not prevent high-temperature steam in the solar heat collectors during a power failure, but rather allows steam to fill the panels without the loss of any collector fluid. The volume of liquid glycol that is displaced by steam as it builds up inside the hot collectors will try to seek refuge in the glycol expansion tank.
