The isobaric system is the expression of the most advanced technology achieved by the Alfatek production. It is particularly effective in the bottling of foamy and carbonated products such as semi-sparkling and sparkling wine, beer, mineral water, soft drinks, etc. Isobaric machines are characterised by certain technical solutions that them one of the most modern and functional systems in their market segment. They are particularly versatile and efficient, require low maintenance and are very simple to operate. With the elimination of the traditional lifting assembly, valve opening is activated directly by the pressure exerted by the bottle on the mouth-press during lifting. In the absence of the bottle the valve remains automatically closed without the need for a detection system. Closing, self-levelling and degassing are controlled by a single rotating device. The format change operation is simplified with the rapid variation of the tank height by electric or electronic control, available on certain versions of the machine.
