Advantages at a glance


aquatherm offers a comprehensive range of pre-insulated pipe systems for industrial applications and large building complexes such as hotel resorts. As a result, the transport of hot or cold liquids succeeds with a very low energy loss. Besides building and industrial applications, aquatherm energy is particularly suitable for district heating/cooling and local heating/cooling. As buried variants, our pipe systems help to transport heating and cooling water safely and efficiently over longer distances, which therefore supplies several buildings, up to entire cities or conurbations, with heat for heating, hot water, or cold water for air conditioning.

Product information


The aquatherm energy pipe system consists of pre-insulated polypropylene pipes, fittings and joints. All service pipes and fittings used for aquatherm energy are made of the material Fusiolen PP-R/PP-RCT. These are insulated with PUR foam and enclosed with a casing pipe made of HDPE.

The pre-insulated aquatherm energy pipe is particularly suitable for energy-efficient heat and cold transport. The system is the solution for many different applications for the distribution of heat and cold fluid, including heating and cooling networks, water distribution, geothermal energy, swimming pool technology, free-space cooling, refrigeration systems, free-space heating, and air conditioning.

New at aquatherm: Leak detection of heating and cooling networks

Leak detection of heating and cooling networks

In some industries, regulations and standards govern the safe operation of pipework. This also applies to district and local heating and cooling networks. Leakage monitoring systems help to fulfil these regulations and make heating and cooling networks even safer. aquatherm is now offering corresponding systems for its aquatherm energy product family, setting new standards for the reliability of pipelines made of polypropylene.

With our leak detection systems for aquatherm energy, we are setting new standards for the reliability of polypropylene pipes in heating and cooling networks. Two systems are offered, each of which locates leaks with pinpoint accuracy by passing on signals and automatically reports them to the central monitoring unit. 

The system from Brandes GmbH is installed in the insulation of the piping system. In the system from the manufacturer Wideco the sensors are located directly on the pipe. Both systems enable early detection of leaks before they lead to property or environmental damage, business interruptions and high repair costs.



Technical details

What should you know about the technical properties of AQUATHERM ENERGY?

aquatherm offers pre-insulated pipe systems in different pressure stages in sizes from 32 - 355 mm. In addition, there are pre-insulated fittings for bends and T-pieces, as well as shrink sleeve sets WTD with fittings for 32 - 125 mm service pipes.

aquatherm energy pipe systems are insulated with PUR foam, which fulfils the functional requirements of DIN EN 253. The foam is homogeneous with an average cell size of no more than 0.5 mm.

The diameter of the PP pipe determines its location and intended use. In order for you to be able to lay a pipeline from the connection to the outlet, the pipe diameter of the individual pipes and fittings must be compatible with each other.

aquatherm energy consists of several layers of material to provide unique strength and insulation properties:

The SDR (Standard Dimension Ratio) is a key figure for indicating pressure resistance. In order to guarantee a certain pressure resistance, a certain maximum SDR number is necessary, depending on the type of material. The following applies: The greater the wall thickness, the smaller the SDR number, the more pressure-resistant the plastic pipe is. The unit indicates the ratio between outer diameter and wall thickness of a pipe. aquatherm energy is available in the following SDR sizes:

The aquatherm energy carrier pipe is made of polypropylene and offers a number of advantages compared to conventional steel pipes:

  • Low weight 
  • No corrosion 
  • High stability 
  • High impact strength 
  • Less roughness inside the pipe  
  • Resistant to most chemicals 
  • Very good welding properties  
  • Self-insulating

How can AQUATHERM ENERGY be processed?

There are many possibilities for the connection of aquatherm energy piping systems. With the processing techniques of aquatherm you quickly create a permanently tight connection.
