REFRIGERATION

 

The right refrigeration solution

Regardless of whether you want to bring a server room to a specific temperature or to cool food, drinks, or medicines, we will work with you to find an outstanding solution for your refrigeration system’s pipework. Our aquatherm blue pipe, made of corrosion-resistant and diffusion-proof polypropylene, is ideal for the transport of cooling media in closed systems and is therefore particularly well-suited for a wide variety of refrigeration applications. The pre-insulated version for underground installation can transport cooling water over longer distances with little or no temperature change. Thanks to aquatherm prefabrication, manifolds and special components can be shipped ready for installation anywhere in the world.

Frequent problems with open return cooling circuits:

 

  • corrosion due to strong oxygen enrichment in the cooling water
  • corrosion due to chemical additives in the cooling water

Compression refrigeration machines for industrial refrigeration

Frequent problems:

 

  • increasing scaling and incrustation of steel pipes,
  • causing increased energy consumption and costs

PROCESSING

aquatherm pipes and fittings are connected by heat fusion, which creates a homogeneous, cohesive unit with no leak paths. Heat fusion connections are stronger than the pipe itself, providing lasting safety at these critical points of a piping system. A properly executed aquatherm fusion creates a permanent leakproof connection.

Depending on the dimensions of the pipe, socket fusion, butt fusion or electrofusion is used.
