VH1000 and VH15 PRESSURIZATION AND HELIUM RECOVERY SYSTEMS: 
Regardless of the application, in order to find a leak in the sealing on tanks, coils, containers, cofferdams, and tubing in which it is possible to introduce helium, you must create a vacuum, introduce the helium flow, trace the flow with a mass spectrometer (leak detector), and then recover it. For these types of applications, ECOVIDE offers two of its time-tested and reliable systems, the VH1000 with helium recovery and the VH15 without recovery.
