Is the DualSun Spring panel compatible with pool water?
Yes. The heat exchanger in our hybrid Spring panel is made of polypropylene: therefore it is compatible with both chlorinated (hypochlorous acid) and saline (sodium chloride) water.
Note that chlorinated or salt water only circulates in a DualSun installation that is in “direct pool” configuration.
In this case all pipes and fittings will be compatible with chlorinated or salt water.
The materials used are:
- EPDM in the inter-panel flexible hoses
- Polypropylene in the DualQuickfit inter-panel fittings
- PVC pressure pipe in the pipes, valves, and fittings of the solar circuit
To prevent chlorine gas formation, a check valve is positioned to prevent the water in the panels from draining back into the pool.
This keeps water in the panels at all times but requires them to be completely drained at the time of wintering.
