Long life-span thanks to top-quality materials

Practical experience:

Tests on solar-rapid 25 pipes more than 18 years old showed that their functionality was faultless, and the heating power was still good!

The material’s resistance against standard pool water maintenance products is especially important.  These products attack rubber and many other materials, and collectors for instance made of EPDM are damaged from within, resulting in black flocculation in the pool water.  
In contrast to this, the material used for solar-rapid is resistant against the standard chemicals in the pool water.

Top test results:

The solar-rapid® 25 pipes are made of high-quality solar-polypropylene.  They are UV-stabilised and resistant to temperatures between –45°C and 130°C.  The solar-rapid® 50 system allows for rapid and easy collector connection.  The material is the same as for the solar-rapid® 25 pipe, which has proved its worth for more than 30 years in the field of solar swimming pool heating.  With the solar-rapid® line system, a new kind of adaptor joint made of high-quality ASA material ensures problem-free glued connection to UPVC pipes and fittings.  ASA Solar is a special composite plastic and was designed specifically for solar technology.  It has significant advantages over ABS and PVC in terms of weather and fracture resistance.
