A gas recirculation unit considerably reduces the gas consumption of the installation. Gas leaving the filtration unit is recompressed and re-used for the plasma torch. The motor is equipped with a variable frequency drive allowing the modulation of the compressor capacity according to the reactor pressure.
Features:
-
Gas handling: Ar, Ar/H2, Ar/He, N2, O2
-
No corrosive gases or condensable vapours
-
Oil-less reciprocating gas compressor
-
Variable speed control
-
Monitoring and control of reactor pressure
-
Outlet filtration for high purity application (optional)
-
Helium concentrator (optional)
-
Oxygen removal (optional)
-
Temporary storage tank
-
H2 monitoring
