The parts of which the ROOS-collector consits are tested under a pressure of 3 bar. Pools usually operate with a pressure of max. 1.5 bar. This guarantees a secure reserve and absolute density.

The special moulding of the ROOS-solar ribbed tube reinforces the material against pressure from outside and against suction from inside due to the partial vacuum resulting from the water's circulation.

Advantage:
Your filter pump is largely relieved from additional pressure that might result from operating the collector.
