Atmospheric air contains approx 21% oxygen & 79% nitrogen. The GasTec® Membrane Nitrogen Generator produces N2 by removing the oxygen in air using membrane separators
Membrane separators are made from hollow polymeric fibers arranged in a shell & tube arrangement. Fast permeate gas such as water vapor & oxygen diffuses thru the wall whilst slow permeating nitrogen travels the length of the hollow fibre as shown below.
Low Nitrogen Production Cost
The average N2 production cost is <0.4 kWh per normal cubic meter at 95% purity, 7 bar output.
Designed for offshore applications
GasTec supplies a wide range of nitrogen systems that meets Zone 2, Group IIB, Temperature Class T3 hazardous area duty requirements.
Equipment are fully skid mounted, factory pre-tested for fast site installation & commissioning.
Convenient & Economical
GasTec nitrogen systems are easy to operate and maintain. It provides the convenience of on-site gas generation and attractive savings over cylinder gases.
Economical - saves 20 to 30% over cylinders gas cost
