Main highlights

This bypass set branches off some pool water and directs it to the solar absorber. It is then fed back to the normal water circulation optimised by 45° angle.
The bypass is required to integrate solar absorbers into the filter circuit.
The absorber should not be integrated directly, otherwise the heat cannot be properly released into the water. Finally, you need to give the water some time to heat up. Therefore, the flow must be reduced by bypass.
Items are delivered individually and unglued
Bypass for solar absorber Ø 50 mm including glue, cleaner and PVC pipe.
