1. GN-30i Overview
1.1 General
The GN-10i generates high density nitrogen gas with PSA(*) technology. The system
consists of a compressor, adsorption tank, buffer tank, pressure regulator, flow rate
meter, flow rate control valve, solenoid valve, piping or control equipments.
(*)P.S.A.
（
Pressure Swing Adsorption
）
P.S.A. is the technology to generate high density nitrogen by pressurizing or
depressurizing (expose to the atmosphere from pressurized state) compressed air using
the properties of adsorber (carbon molecular sieve) to adsorb and desorb oxygen.
1.2 Features
・
Easy to conduct maintenance work as the panels on top or both sides can be
removed.
・
Automatically switched between 50Hz and 60Hz.
・
Operation starts simply by pressing Run/Stop button. Once started up, GN-30i
generates nitrogen gas automatically.
・
To stop operation, simply press Run/Stop button.
・
The compressor is long-life and low-noise type.
・
Safety circuit is built inside to detect the compressor trouble. GN-30i stops
automatically when a trouble occurs in the compressor.
・
Drained water is evaporated by electric heater and PSA exhaust desorbed gas.
There is no need of piping for drained water.
