Operating Principle:

Making use of pressure swing adsorption technology, adopting zeolite molecular sieves as adsorbent, under certain pressure, utilizing the different absorb ability of N2 and O2 to surface of zeolite molecular sieve, with PLC controlling open and close of Pneumatic valves to achieve alternative circulation between two Towers, adsorbing when pressure rises, desorbing when pressure drops, realizing oxygen and nitrogen separation.
After further purification process, medical oxygen with desired purity is obtained.

Salient features of High Purity Oxygen Generators:

Full Automation
All systems are designed for un-attended operation and automatic Oxygen demand adjustment. Lower Space Requirement and Short installation period The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory. Installation is very easy and convenient.

Fast Start-up
Start-up time is about 30 minutes to get desired Oxygen purity. So these units can be switched ON & OFF as per Oxygen demand changes.

High Reliability
Very reliable for continuous and steady operation with constant Oxygen purity. Plant availability time is better than 99% always.

Molecular Sieves Life
Expected Molecular sieves life is more than 10-years i.e. whole life time of Oxygen plant. So no replacement costs.

Low Investment and Energy Consumption
Initial investment is low as compared to other oxygen generating plants and the energy consumption is also very less when compared to others.

Simple operation and maintenance
Being fully automatic the operation is very simple and does not require any complex understanding of the product and thus the maintenance is simple and inexpensive.

Oxygen Filling Booster for filling cylinder:

The Booster operates on the differential piston area principle. A large area piston drives at low air pressures, drives a small area compression piston which converts input gas to higher pressure. The output gas or discharged pressure is determined by the ratio between the area of the drive piston and the operating air pressure and the available pre-charge pressure supply.
The function of the pre-charge pressure is to charge the high pressure cylinder inside the booster with gas , reducing the time need to reach high pressures
