REFRIGERATION

 

We ensure the right temperature – always and everywhere

A life without refrigeration is hard to imagine. Foodstuffs must be cooled precisely during production, storage, and transport; ice rinks can only operate when kept at optimum temperatures, and refrigeration technology provides the basis for air-conditioning systems in our apartments, office buildings, and hotels. When it comes to refrigerant circuits, aquatherm offers you the right piping system. In refrigeration plants of all sizes — from split units to compact refrigeration systems to central cold-water systems — aquatherm pipes are the right choice.

With our aquatherm blue pipe, corrosion due to strong oxygen enrichment or chemical additives in cooling water is a thing of the past. Thanks to its special material properties, aquatherm blue pipe is characterized by high chemical resistance and a high degree of safety over its entire service life. The fibre composite technology ensures high pressure capability and dimensional stability, as well as minimum length expansion with temperature changes. aquatherm’sfusiolen polypropylene makes it immune to scaling and corrosion. Since it is a fully heat-fused system, it is virtually leak-free.

Our pre-insulated pipes are particularly well-suited for underground installation. They prevent condensation and the outer shell is oxygen-tight, making pre-insulated aquatherm blue pipe ideally suited to transport cooling water over long distances.

Moreover, we offer custom-designed prefabricated components and manifolds which can be shipped ready to install anywhere in the world. We are happy to assist you!

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.
