SIEMENS SIMATIC HMI
NITROGEN GENERATION UNIT Allows monitoring / control of main process parameters, displays gas purity,

PSA MODULAR flow rates, totalized gas flow, functioning hours, maintenance alerts etc.

Up to 99,999% Nitrogen / 150 Nm3/h

Modular PSA generators implement a unique Pressure Swing Adsorption technology and can produce nitrogen purity of Flow (m3/h) Dimension
up to 99.999% with pressure up to 8.5 bar (standard range) plus customized versions of up to 11 bar. Model 10 50 100 500 Pressure Weight
