HIGH PURITY NITROGEN EQUIPMENT / ULTRA HIGH PURITY NITROGEN EQUIPMENT
KDN high purity nitrogen equipment, the product is based on the KDN pure nitrogen equipment based on the use of a number of independent integration of innovative technology(technology):
·Innovative design of the pressurized air expansion refrigeration low pressure tower with a double distillation column system of nitrogen flow, the unit energy consumption per unit of nitrogen is lower than 0.2KWh/m3N2, the extraction rate is greater than 85%;
·Low temperature distillation method was used to remove the high purity nitrogen in the distillation column of nitrogen , and the nitrogen purity reached 99.9997%;
·Improved general gas bearing turbo expander, developed a new type of gas bearing turbo expander, bearing capacity increased by 2.5 times.

Types of technological processes of main high-purity nitrogen equipment
·Single column distillation with waste gas expansion high purity nitrogen equpment, with nitrogen pressure of 0.45~1.0MPa
·Single column distillation with air expansion high purity nitrogen equipment,with nitrogrn pressure of 0.2~0.3MPa
·Double column distillation with waste gas expansion high purity nitrogen equpment, with nitrogen pressure of 0.2~0.25MPa
·Double column distillation with air expansion high purity nitrogen equipment,with nitrogrn pressure of 0.2~0.3MPa
