Decades of experience in the production and the application of PP-R-pipe systems and the current ambition of continuous development led to numerous improvements of the aquatherm system technology. Newly opened markets set a high standard of quality to make even larger demands against the pipe material. Various fields of application require the greatest possible independence of the material to be processed. Raw materials with new properties are required. aquatherm has developed and produced their own, innovative PP-R-materials which meet the requirement of a global market in the potable water and heating technology, in the airconditioning and chilling engineering, in the industrial and agriculture economy, in shipbuilding as well as in fire protection. Successful results of this research are fusiolen® PP-R, fusiolen® PP-R C or fusiolen® PP-R FS. All aquatherm PP-R-pipes and fittings are made of fusiolen® PP-R. Special heat and extraction stability are only two of the features of this material. Its physical and chemical properties are well-suited to the transfer of potable water and to the heating field. Above all, the good welding properties and fusion, resulting in a permanent connection, have made the aquatherm systems and the raw material fusiolen® PP-R well known worldwide.
Hygienic suitability
Chemical and thermal disinfection
Contrary to the disinfection of drinking water, the disinfection of a system is a discontinuous measure, comprising a drinking water system from the area of contamination to the tapping point of the consumer. In general, a disinfection is to be applied temporarily only in case of a proven contamination. further information
Fire protection
The aquatherm PP-R pipe systems comply with the requirements of the fire classification B2 DIN 4102 (normal inflammable). Compared to natural products like wood, cork or wool, aquatherm PP-R-pipes do not produce any gas toxicity. In case of fire, there is no risk of dioxin emissions. further information
Guidelines
The following laws, decrees, guidelines and standards have to be considered on planning and designing aquatherm PP-R-pipes for potable water and heating installations. further information

Faser-composite technology
aquatherm is proud to manufacture its own glass-fibre reinforced polypropylene composite. Our three-layer pipes are extruded with a fibre-reinforced middle layer that strengthens the pipe and restricts expansion and contraction.
The benefits of this construction include:
- linear expansion reduced 75 percent compared with standard PP pipe
- 20 percent increased flow rate due to smaller required wall thickness
- longer support intervals and reduced number of clamps compared to standard plastic pipes
- optimum cost-performance ratio
- high stability
- lower weight
- high impact resistance
- simply cut and heat-fuse
