The Solar Sun Rings are innovative devices for solar heating of pools and Spas.

These consist of two layers of heavy vinyl that is resistant to UV rays.
The upper light layer retains air and transmits the sun-light to the lower blue layer.
The blue layer absorbs approximately 50% of the sun-light and converts it into heat.
Remaining light passes through this layer to heat the deeper waters.

These have been designed for most of the cleaning systems and pool-robots.
