Introduction to Generator Hydrogen Gas Cooling System

The gas unit for generator gas cooling comprises the components necessary to fill the generator with hydrogen, maintain it under pressure, check the gas purity and evacuate the generator. To prevent the formation of explosive gas mixtures, the air in the generator is expelled with CO2 prior to filling with H2.

H2 gas is then pumped in, displacing the C02. When evacuating the generator, the order is reversed. The H2 is first expelled with CO2; afterwards the CO2 is expelled with compressed air (dry and oil-free).
