The system alsocomes with a liquid nitrogen Backup System forultimate reliability.
The N180 has a turbine which eliminates the liquidassist requirement and enables the plant to producesmall amounts of liquid nitrogen .
The N180 is designed to operate without a nitrogencompressor for pressures up to 85 psig and with a
nitrogen compressor for pressures above 85 psig. Thisallows the N180 to have the lowest possible unitpower. Plant capacity varies with operating pressure.
