Is the DualSun SPRING panel compatible with pool water?
SPRING4
It is important to distinguish between our two generations of SPRING currently available:
For more details on the specifications of the models, you can refer to the dedicated article: |
SPRING4
DualSun SPRING4 panel is not designed for a direct pool heating system. Indeed the heat exchanger in aluminum is only compatible with glycoled water.
SPRING3
Yes. The heat exchanger of 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.
