Diagram of a CryoGAN nitrogen generator

Powerful as a matter of principle Irrespective of their capacity, the basic principle is the same for all CryoGAN nitrogen generators and consists of the following components

Air compression: The air is filtered and compressed to 7 to 10 bar and then pre-dried Air purification: Two adsorbers operated alternately separate out air components Heat transfer: Through heat exchange with the cold separation products, the air in the main heat exchanger is cooled to near the condensation temperature. In this process, the product flows are heated to the ambient temperature. Rectification: The “heart” of the system separates the air into high purity nitrogen and an oxygen-enriched residual gas. The nitrogen is separated into two flows, one of which is fed back to the rectification column as a return flow after condensation. The other one flows through the main heat exchanger, where it gives off its “cold energy” to the air before escaping the system as a gaseous product. Cold source: The system’s refrigeration requirement is met by either the use of liquid nitrogen or the cold produced by an expansion turbine. Back up: The presence of a backup system allows our client to continue working during preventive maintenance, equipment maintenance and possible force majeure situations. During such periods, the Customer will be supplied with Oxygen through a back-up system. Our regional logistics network with centrally managed Europe-wide coordination, combined with sophisticated production planning, ensures that every single customer receives a reliable supply of technical gases from Messer, even during planned and unplanned downtimes

Powerful as a matter of principle Irrespective of their capacity, the basic principle is the same for all CryoGOX oxygen generators and consists of the following components

2. Air purification: Two adsorbers operated alternately separate out air components 1. Air compression: The air is filtered and compressed to 1,5 to 8 bar and then pre-dried. 3. Heat transfer: Through heat exchange with the cold separation products, the air in the main heat exchanger is cooled to near the condensation temperature. In this process, the product flows are heated to the ambient temperature. 4. Rectification: The “heart” of the system separates the air into high purity oxygen and an nitrogen-enriched residual gas. The oxygen is separated into two flows, one of which is fed back to the rectification column as a return flow after condensation. The other one flows through the main heat exchanger, where it gives off its “cold energy” to the air before escaping the system as a gaseous product. 5. Cold source: The system’s refrigeration requirement is met by either the use of liquid nitrogen or the cold produced by an expansion turbine.

How can I quickly understand what exactly I Need?

Does your process demand reliable, secure and consistent onsite supply of non-cryogenic and cryogenic industrial gases? Onsite gas production facilities make sense wherever there is a constant high demand for industrial gases. Trust the team at Messer to design and deliver the purity and quality of an onsite supply system that fits your demand profile.
