The MULTINUPI system of multilayer pipes and BRASS and PPSU mechanical pressure fittings for the transport of drinking water was installed in a private hospital in Brussels. MultiNUPI fittings are of press-fitting type, i.e. installed by mechanical pressure. The innovation of the MultiNUPI system is the integration of the new MULTI-PRESSING range which allows to switch from a single clamping system (using only "U" profile jaws) to a multiple clamping system, suitable for 5 different types of clamps: TH - U - H - B – F. It will no longer be necessary to change the equipment according to the type of fitting, but it is the fitting that adapts to the equipment already supplied. The fittings are available with BRASS and PPSU body. The range of fittings of the MULTI-PRESSING system includes diameters from 16mm to 32mm with the addition of diameter 20x2mm. Diameters 14mm and 40mm to 63mm are only available in single clamping system.
