aquatherm red pipe is the first plastic sprinkler pipe system certified by VDS Schadenverhütung GmbH, Europe’s largest institute for company safety. The material used, fusiolen® PP-R FS, was developed for the special requirements of sprinkler systems. aquatherm red pipe offers a high level of safety due to its flame retardant properties and its corrosion resistance. The welding of pipe and fitting also ensures a tight connection.

Technical specifications

  • low weight compared to metal piping
  • Corrosion resistance and resistance to chemicals
  • short processing time
  • tight connection of pipe and fitting by fusion technology
  • no seal: sealing elements are not required

Our material fusiolen®
Decades of experience in the production and application of polypropylene piping systems and the simultaneous endeavour for continuous further development have led to numerous improvements of the aquatherm products.

The basis for this are the innovative polypropylene materials developed and produced by ourselves, which became known as fusiolen® known as fusiolen. Successful results of research & development are fusiolen® PP-R, fusiolen® PR-R FS and fusiolen® PP-RCT.

is characterized, among other things, by its special high-heat and extraction stability. Especially the good weldability and the fusion to a homogeneous unit have made the material and the aquatherm polypropylene systems known worldwide. Its physical and chemical properties are adapted to the special requirements of the respective areas of application, such as drinking water, heating and cooling or sprinkler applications.

fusiolen® is an environmentally friendly material that can be recycled and reused in various applications. No environmentally hazardous substances are produced either during processing or during subsequent disposal.
Worldwide, fusiolen® is valued for its durability, chemical purity and low environmental impact.

Fire protection

The aquatherm PP-R pipe systems meet the requirements of the building material class B1 DIN 4102-1 (hardly inflammable). Compared to natural materials such as wood, cork or wool, they do not exhibit increased fire gas toxicity. This means that no dioxin is produced during incineration. further information


The following laws, regulations, directives and standards must be considered when planning and executing aquatherm sanitary and heating installations. further information

Fibre composite pipe

By the manufacturing process developed by aquatherm the integration of a special fibre mixture within the material polypropylene is realized.

The result of this innovative technology is the unique direct composite of the material components.


  • the linear expansion is reduced by 75 % compared to conventional PP pipes
  • the flow rate is increased by 20 % with the same load capacity due to thinner wall thicknesses
  • high stability
  • the coefficient of linear expansion is almost identical to that of metallic pipelines, so that, compared to all-plastic pipes, support spacing can be increased and fastening clamps can be dispensed with
  • optimal price/performance comparison
  • lighter in weight
  • high impact resistance
  • simply cut and weld
