Helium Charging Machine and Recovery Systems

Helium Charging Machine

Vacuum, tracer gas (H2 or He) mixtures Pressurization unit

AMIATA, has been designed in particular for making pressure tests and leak test of refrigerating units with the use of inert gas or tracer gases such as helium or nitrogen/hydrogen, according to the ISO 10156 Standard; before the charge of the test gas it is possible to perform a vacuum cycle so to get a first cleaning of the unit and to make a preliminary tightness test.

AMIATA is ideal for the tracing of components and refrigerating units, on production lines for any kind of appliance, wherever a pressure test or/and a trace gas leak test is required.
