Umulig Engineering is the official partner of Aquatherm in South Africa. Aquatherm is the world leader in polypropylene (PP-R) pipe system. Aquatherm offers pipe systems with many applications due to their special characteristics and versatility. The Aquatherm pipe systems are applied in all fields of:


Umulig Engineering suppliers the following systems, including all elements for the pipe system installation for chilled, hot fluid and various industrial applications:

  • Pipes in straight lengths and/or coils
  • Fittings
  • Flanged joints
  • Welding devices and machines
  • Weld-in saddles
  • Manifolds
  • Shut-off devices
  • Cutting and peeling tools
  • Installation guide and fastenings
  • Transition joints from PP-R to metal or from metal to PP-R

The following Aquatherm PP-R pipe systems are now available in South Africa.

Fusiolen® PP-R

Aquatherm has 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 air conditioning 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-RP,
  • fusiolen® PP-R C
  • fusiolen® PP-R FS


The environmentally friendly material polypropylene fusiolen® PP-R is recyclable and can be ground, melted and reutilised for various applications.
e.g. motor-protections, wheel linings, laundry baskets and other kinds of transport boxes. There are no polluting substances with PP-R either in its processing or in its disposal.

Metal Deactivators

By adding suitable food-approved additives the risk of material damage caused by metal under extreme conditions of application is substantially reduced.

Higher long-term heat stabilization

The long-term heat stabilization has been increased to resist to the potential effects of peak temperatures within higher safety parameters.


Potable water is one of the most controlled commodity goods. The domestic supply system should influence the water on its way up to the taps as less as possible. The choice of the right potable water pipe system and its material is of decisive importance.


Aquatherm green pipe systems are suitable for all different qualities of potable water. The environmentally friendly and hygienically enhanced potable water pipe system made from fusiolen® is physiologically and microbiologically harmless. The technical suitability of the Aquatherm pipe systems has been evident worldwide for more than 30 years. The extrapolated service life of Aquatherm PP-R-pipes is more than 50 years. Peak temperatures of 100 °C arising from short disruptions are unproblematic. Permanent temperatures from 70°C up to 90 °C reduce the service life of the pipe.

Using Aquatherm PP-R-pipes for heating or air conditioning applications the pressure- and temperature conditions according to table are valid.
