Gas Generation

Nitrogen and Oxygen PSA Generators are systems that use Pressure Swing Adsorption (PSA) technology to separate nitrogen and oxygen from compressed air. The process involves passing compressed air through a bed of adsorbent material, which selectively adsorbs either nitrogen or oxygen. while allowing the other gas to pass through.

Why Pressure Swing Adsorption?

How it works

On-site Nitrogen and Oxygen PSA Generators

Our Nitrogen and Oxygen generators are based on the Pressure Swing Adsorption (PSA) technology.
Development and production processes employ only components of the highest quality
Increase flexibility and cost-effectiveness with our PSA solutions and produce your own Nitrogen and Oxygen where and when you need it without compromising on quality
Used by a range of industries, our PSA generators allow you to produce the gas exactly where you need it, when you need it and in the quality that you need.
Custom-made generator systems for cases where our standard range of generators does not fit your specific requirements
Our PSA solution pays for itself in a very short time.

Pressure Swing Adsorption

How PSA works

STEP 1

The PSA process starts as clean and dry compressed air enters the first cylinder (left). ✓ The unwanted Nitrogen / oxygen gas is adsorbed by the pellets at high pressure, but the required gas molecules pass through. The resulting high-purity gas is stored in the buffer tank. ✓ During this step of the cycle, the second cylinder (right) is cleaned.

STEP 2

✓ Next, the pressure between the two cylinders is equalised.

STEP 3

When the pressure drops in the left cylinder and the pellets are saturated, waste products (Nitrogen / oxygen) are blown out through the exhaust system. ✓ The process is repeated from step 2 but this time in the right cylinder. Pressure builds up, followed by equalisation. ✓ The process is repeated and a constant production of required gas is established.
