Good received of the systems for district heating of Rehau in Expobioenergía

In this edition, Rehau took advantage of the occasion to present, among others products, his new casket and piece in T like the best solutions for the union of pipes Rauthermex and Rauvitherm, being this last one of the most stood out proposals of the mark regarding systems of distribution of heat to distance. A technician of Rehau realised, besides, a demonstration on how join the pipes of simple form through the manguito electrosoldable Fusapex, obtaining big success between the assistants.

Fits to stand out that in the stand exposed several projects of district heating llevar with solutions Rehau, that show the wide experience of the signature inside the sector of the biomass, as well as the know-how that contributes to his projects.

This project arose of the need to find a source of alternative power to the conventional with the aim to reduce the energetic consumptions of the population, using for this the pertinent forestry mass of the cleaning of the forestrys of the zone. With the interest for implementing a plant of biomass, opted by the installation of a network of district heating able to resupply of hot water for heating and sanitary ware hot water to distinct buildings of municipal property and to the medical centre of the population.

The advice ‘in situ' of the technicians of Rehau in each one of the phases does indispensable because of the variety of interventores that is used to to have in these projects, since it results basic to loan the maximum attention to the details to ensure the best results. Of this form, obtains a greater efficiency in the implementation of the systems of the mark in the work.

The technical complexity of this project was due to the orography of the municipality, since it had to cross two rivers and a rail network, by what had to realise aerial stretches for sortear these zones. With this coyuntura, opted by the installation of the system of pipes and accessories of last generation Rauvitherm of Rehau developed for the distribution of power to distance.

Rauvitherm Is a pipe composed in great quantity inner of PE-Xa and with an additional layer EVOH against the diffusion of oxygen. It stands out by his estanqueidad longitudinal, his high resistance to the high temperatures as well as by his big flexibility, since it is revestida with one founds tubular anillada of polietileno foamed. Besides, it has of a wide rank of diameters (from 25 mm until 140 mm) in function of his use and offers the possibility to cut to measure, what converts this system in the ideal for this type of installations.

To face up to the derivaciones, one of the most problematic points in the network of distribution, Rehau offers a wide range of technicians of union to link pipes of distinct diameters as well as for points of consumption. With the technology of casquillo corredizo, the manguitos of external isolation with the foam PU and the manguitos termorretráctiles, the connections between the pipes are totally tight to the water and isolated térmicamente to face up to the low temperatures of the Pyrenean zone where finds the work.

The investigation and the development of new technologies, as well as the projects llevar by the mark, allow to show the importance and the effectiveness of the distinct systems Rehau of catchment and distribution of renewable energies.
