The HydraLux is a unique automatic pool cover that utilizes extruded rigid PVC slats. This slat design eliminates the rope / track / leading edge bar interface as with traditional automatic pool covers, and can provide automation on pools that previously could not accept an automatic pool cover.You are no longer limited in your pool design as the HydraLux can be cut to any converging shape. Water features such as laminares and spa overflows can run while the cover is closed.
