The GA-200-N nitrogen generator (hereinafter referred to as the generator) is a modification of the GA-200 nitrogen generator and is designed primarily to work with a storage tank (receiver) in which a certain "reserve" of nitrogen can be created. Unlike the GA-200, the GA-200-H generator has a built-in pressure monitoring system for nitrogen accumulated in the receiver, which puts the generator into "standby" mode when the maximum pressure value is reached in the receiver, and restarts the generator when the pressure drops below the minimum value. This work allows you to reduce energy consumption and increase the service life of the compressor feeding the generator.
