DAISHIN / MAYEKAWA Nitrogen Gas Generating System
It can remove oxygen and carbon dioxide gas and water in the atmosphere by the method of PSA in a short time. It can provide a stable supply of high purity nitrogen gas. Among the different variations, we propose an optimal device to the structure of the ship.
※What is the PSA system?
It stands for Pressure Swing Adsorption system. By utilizing special carbonate molecular sieves, nitrogen gas is produced by removing oxygen from the pressurized air.
Main Features
- Low electricity consumption.(about 2/3 of membrane type)
- Compact designed units by the adoption of high performance adsorbent.
- Quiet design
- Wide range of purity of nitrogen gas between 95% and 99.99%.
(If higher purity of nitrogen gas is required)
High performance adsorbents
New carbon-based adsorbent with special phenolic resin as a raw material.
MSC(carbon molecular sieve) of a high-performance synthetic polymer as a raw material, is characterized as follows.
- ・Cylindrical with 1mm diameter and 2 ~ 3mm length.
- ・It has excellent homogeneity, since made from synthetic phenolic resin.
- ・It can be separated and purified nitrogen gas with high efficiency, since has a unique pore structure.
- ・Excellent durability and wear resistance.

PRISMR Membrane Technology
The key component of the nitrogen systems is the PRISM membrane separator modules. Each module contains thousands of hollow fiber membranes allowing the oxygen water vapor and carbon dioxyde in compressed air to be selectively removed, resulting in a nitrogen rich product stream. By adjusting the airflow rate through the membrane module, different nitrogen and flow rates can be produced.
The membranes are formed into hollow fibres to obtain maximum membrane surface per unit of volume. Thousands of fibres are bundled into a casing that protects the fibres, routes the gas properly from feed to product end - and creates handy and standardized units that can easily be stacked together for modular capacity increase of the system.
