Our lining system Nisa 2011 version 2014 is a solution to necessity of reconstruction a single-wall tank to a double-wall tank, according to requirements of valid legislation.

The basis of the system is a flexible plastic inner liner, which is simply inserted into metal tank which was first lined with conductive non-woven fabric. The liner then serves in the tank as a second wall, qualitatively equal to the metal wall. Vacuum is established in an interspace between both the walls. The vacuum is then continually maintained and monitored, by use of a leak detector. Any leak in any of the walls is immediately detected and announced. This technology has been in use over a long period, its quality has been verified by time, and its properties have been updated regularly.

Advantages of the lining system:

  • fast installation (within one or two days)
  • resistance to all sorts of fuels (petrol, diesel, biodiesel, jets, AdBlue, ethanol)
  • inner corrosion is stopped immediately (thanks to absence of oxygen)
  • conductive treatment allows usage in Ex-zone
  • constant vacuum monitoring signalls any leak in a tank immediately

Certificates: The system meets requirements of EU standard 13160-7:2016 as well as of directive ATEX 2014/34/EU. Our certificates to view.
