EFFICIENT DISTRICT HEATING CONSTRUCTION

DISTRICT HEATING THAT PAYS OFF

District heating offers the highest security of supply among all energy sources. The heat generated from fuels and increasingly renewable energies is inexpensive and convenient for the user, yet not available everywhere. This is because, in addition to technical aspects, economic aspects are decisive in the development of supply areas. Trenchless installation of the transport and supply pipes makes it possible to expand the supply network in an economically and ecologically efficient manner.

EFFICIENCY THAT LASTS

With our NODIG systems you bring the medium pipes for water or steam district heating from the generator to the transfer station and from there to the end customer‘s supply room – force-fit and without heat loss. Various proven and flexible techniques ensure that trenchless installation of insulated plastic pipes works just as quickly, gently and cost-effectively as that of corrugated steel pipes. This is what we understand by efficiency.

AT A GLANCE

  • Efficient underground installation of flexible and rigid media pipes made of standard materials along roads, under traffic and waterways along linear and flexible bore paths
  • Unproblematic parallel installation of the supply and return lines
  • Trenchless installation of house connections lines from the transfer station to the building
  • Proven and flexible techniques for the safe underground installation of various types of pipes
  • Maximum planning and technical safety according to the latest technical standard
  • Precise proof and documentation of position, function and tightness of the new pipelines
