Optional Brandenburger Liner BB2.5 for rehabilitation of decrepit sewers

The rehabilitation liner made of E-CR glass-fibre takes over the task of sealing the decrepit old pipe as well as the static support of the entire old pipe ground system.

Heat exchanger mat

If a rehabilitation of the old pipe was necessary, a custom-made heat exchanger mat made of plastic with integrated chambers is attached to its base or directly on the base of the old pipe.

Inner liner BB2.5

The last step in the sewer is the installation of a thin-walled Brandenburger Liner BB 2.5 inner liner for permanent fixation and protection of the heat exchanger mat between inner liner and rehabilitation liner or old pipe.

Collecting pipes

Making the connection of the supply and return line of the heat exchanger mat with the collecting pipes in the shaft is the last step before transferring the heating medium to the heat pump.

Heat pumps

Heat pumps can be installed and controlled with a Heatliner just like with any conventional heat exchanger.
