Made of corrosion-resistant polypropylene, aquatherm blue pipe is ideal for the transport of cooling and heating media in closed systems. It is particularly well suited for a wide variety of industrial applications. The physical properties of the plastic, such as its high temperature capacity and pressure resistance, are tailored to the specific needs of the heating and cooling sector. aquatherm blue pipe is joined via reliable heat fusion, which produces a virtually leak-free and cohesive unit with excellent safety and durability. aquatherm blue pipe combined with aquatherm green pipe fittings provides all the technology and components required for the piping installation of commercial air conditioning and heating systems and industrial applications.

Our material fusiolen®

Decades of experience in the manufacture and use of polypropylene piping systems and the simultaneous striving for continuous further development have led to numerous improvements in aquatherm products.

The basis for this are the innovative polypropylene materials developed and produced by us, which operate under the name fusiolen®
became known. Successful results of research & Development is fusiolen® PP-R, fusiolen® PR-R FS and fusiolen® PP-RCT.

fusiolen® stands out due to its special high heat and extraction stability. Above all, the good weldability and the fusion into a homogeneous unit have made the material and the aquatherm polypropylene systems known worldwide. Its physical and chemical properties are tailored to the special needs of the respective areas of application such as drinking water, heating and cooling or sprinkler applications.

is an environmentally friendly material that can be recycled and reused in various applications. Environmentally hazardous substances do not arise during processing or later disposal.
Worldwide, fusiolen®  is valued for its durability, chemical purity and low environmental impact.


 Fire protection

Aquatherm PP-R piping systems meet the requirements of building material class B 2 DIN 4102 (normally flammable). Compared to natural materials such as wood, cork or wool, they have no increased fire gas toxicity. This means that no dioxin is produced during combustion. Further Information 


The following laws, ordinances, guidelines and standards must be taken into account when planning and executing aquatherm sanitary 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
