Inversion units for pipe rehabilitation

epros®Inversion units

For saving time and costs, utmost safety at work and better mobility we recommend the epros®DrainLining method, using epros®InversionDrums as the desirable solution. This method is allowing for smooth renovation via cleaning or inspection holes or any other known pipe openings. epros®InversionDrums are composed of transportable pressure vessels, made of steel or stainless steel, designed to installation pressures of up to 1.5 bar (available on special request converted to max 3 bar and with pressure vessel approvals, e.g. TÜV, DEKRA or similar) and they are availabe in differenz sizes - according to your needs.
