THE MERLIN FLOW SYSTEM
The Merlin system works like a small commercial RO system. It uses two
membrane elements in series to produce the high flow of permeate. The
concentrate from element one is channeled into the inlet at the second
element, Figure 9.
Figure 9 The Merlin Flow Pattern
SHUT-OFF PRESSURE
The Merlin stops the flow of inlet water when the system is not in use. An
internal shut-off valve will close when pressure in the permeate line
reaches approximately 1/3 of the system inlet pressure. This function
saves water by turning the unit off when permeate water is not being
used. The inlet valve will open, and the Merlin will start making permeate
water when pressure in the permeate line drops to approximately 11% of
the system inlet pressure.
