Electrolyte Circulation Loop
2

There are separated electrolyte pumping loops on the hydrogen and oxygen sides of the system.
Each loop consists of a phase separator which serves as a reservoir, a centrifugal pump, a heat
exchanger, filter and flow switch. Downstream of the flow switch, the electrolyte enters the
respective side of the electrolysis module. A mixture of liquid and hydrogen(or oxygen) gas flows
back to the phase separator through the module outlet pipe. All of the electrolyte loop
components are supported on the floor of the cabinet. The electrolyte containment materials
including vessels, pipe and fittings are fabricated from low carbon series 316L stainless steel.
Connections are seal welded accept where access may be required. Access connection fitting are
CPV style O-ring connections.

Cooling Water Systems

Refer to figure, the system consists of two cooling water loops. The cooling water loop consists of
an inlet filter, a cooling water flow control valve, the heat exchanger and gas coolers. All wetted
process portions of both cooling loops are constructed of stainless steel. The gas coolers are
connected in series on the water side, with stainless steel tubing and Swagelok style fittings.
