The target was to develop such an inversion equipment that due to its tight and specially divided inner space ensures the continuous inversion of a liner regardless of diameter and length.

There are only a few equipments alike in the market. These can be grouped into two categories: those that invert the liner sectionally and those that can invert the liner continuously. The maximum length of a liner that the sectionally operating equipments can invert in one go is 4m.  Whereas the equipments from the other category can invert the liners continuously the maximum pressure they can operate with is 0,5-0,6 bar, which is only enough for liners with polyurethane coating and with smaller diameters.

Throughout the development process of ULTRAGUN we were not just focusing on the limitations of the CIPP technologies but also on the weaknesses of existing inversion equipments. As a result of a long term planning and designing ULTRAGUN was created and serves as a firm solution to the problems of most of the CIPP technologies discussed earlier, moreover it is one of the first equipments to be able to invert pressure liners used for the rehabilitation of pressure pipes.

ULTRAGUN has such a multi-space structure due to the tight and special division of its inner space that enables the equipment to invert liners of any kind regardless of diameter and length even at 4 bar pressure, which is known as the best inverting pressure possible. Currently there are two types of ULTRAGUN existing for 200mm and 600mm diameters: ULTRAGUN-200 and ULTRAGUN-600.

With ULTRAGUN longer sections can be relined in one step, which can shorten the total time spent on the relining project (sometimes even with 15%), moreover this can result in at least 50% less earthwork.
