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.

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.
