Package 1
AutoPure Technology
At start-up or if purity drops, the vessel is purged until the nitrogen reaches the required purity. Only then does the outlet open – ideal for food and pharma.

Why generate your own
Save money and stay independent
Liquid nitrogen and cylinders are expensive: you pay for transport, rental, storage and long-term contracts. An on-site generator makes nitrogen from compressed air – continuously, transparently and at the purity you actually need. Many systems pay for themselves within a few years.
Lower costs
You only pay for compressed air and electricity. For laser cutting, the two-stage H2KAT process saves up to 70% compared with liquid nitrogen.
Independence
No lead times, cylinder changes or supplier price increases. Nitrogen is available 24 hours a day.
The right purity
From 95% for inerting to 99.9995% for lasers and electronics – without paying for purity you don't need.
Less CO₂
No tanker deliveries. With compressor heat recovery, primary energy demand drops even further.

PSA, membrane or H2KAT
All three technologies extract nitrogen from ambient air. The right one depends on purity, flow and energy consumption.
Pressure swing adsorption (PSA)
Compressed air flows alternately through two vessels filled with carbon molecular sieve (CMS). Oxygen binds to the sieve surface while nitrogen molecules pass freely into the product receiver. When the sieve in the first vessel is saturated, the process switches to the second; the first regenerates by pressure relief and purging. The result is a continuous flow of nitrogen.
- purity 95–99.999%
- flows from 0.85 to 1,250 Nm³/h per unit
- long-life CMS made from coconut shells

Inside a PN generator
Eight reasons for a long service life
Every PN generator is built for continuous industrial operation. Click a point on the image.
Control packages
More from the same generator
PN generators can be extended with packages that raise reliability and cut energy use.
Package 2
Energy Efficiency Control
The controller measures demand and purity and extends the cycle time at partial load. Fewer switching cycles mean less purge loss and much lower air consumption.
Maximum savings with fluctuating demand
Option
Base load switching
Two redundant systems run as master and slave. Switching is automatic by pressure and flow, and servicing takes place without downtime.
Supply guaranteed at all times
Option
Redundant valve block
A second valve path at inlet and outlet covers about nine out of ten faults. Valves can be replaced during operation.
Redundancy without a second generator
PNK + H2KAT
Highest purity with the least air
For 5.0 or 5.5 nitrogen, a conventional PSA generator needs a lot of compressed air. The PNK and H2KAT combination uses 40–50% less, so the generator, compressor and air treatment are all smaller.
The H2KAT concept
N₂ 3.0 + H₂ → N₂ 5.0 + H₂O
- Lower investment: smaller compressor, generator and air treatment
- Air factor of only 2.9–3.3
- Extremely compact – also suitable for container installations
- Continuous O₂ monitoring of both units on one screen
- Expandable with booster and storage up to 300 bar
PNK and H2KAT combinations
| PNK generator | Catalyst | N₂ flow 5.0 |
|---|---|---|
| PNK 150 | H2CAT 20 | 20 Nm³/h |
| PNK 270 | H2CAT 40 | 40 Nm³/h |
| PNK 350 | H2CAT 60 | 60 Nm³/h |
| PNK 500 | H2CAT 80 | 80 Nm³/h |
| PNK 750 | H2CAT 100 | 100 Nm³/h |
| PNK 1000 | H2CAT 150 | 150 Nm³/h |
| PNK 1500 | H2CAT 200 | 200 Nm³/h |
| PNK 2000 | H2CAT 300 | 300 Nm³/h |
Hydrogen supply is not included. H₂ consumption is about 2 l/h per m³ of nitrogen at 99.9% inlet purity.
Laser cutting
Cutting gas from your own production
Nitrogen creates an oxygen-free atmosphere around the laser beam: edges stay free of oxidation, contours are precise and the beam path stays clean. The IMT PN Laser package combines generator, H2KAT, oil-free booster and storage in one system.
- up to 70% lower costs than liquid nitrogen
- nitrogen up to 99.9995%, compressed to 300 bar into cylinder bundles
- for fibre and CO₂ lasers
- remote monitoring and data logging
Oxygen too
PO oxygen generators
The same PSA technology with a zeolite sieve produces oxygen at 90–95% purity. For fish farming, wastewater treatment, ozone generators, glassmaking and welding.

FAQ
What customers ask us most
What information do you need to size a generator?
Required flow (Nm³/h), purity (% or ppm residual O₂), operating pressure, duty cycle and a description of the application. Data on your existing compressor and dryer also help, as compressed air quality and pressure directly affect generator capacity.
PSA or membrane – which is better?
Membranes are simple, quiet and have no moving parts, suitable up to 99.5%. PSA reaches up to 99.999% and is more energy-efficient at higher purities. For 5.0 and above, the PNK and H2KAT combination is the most economical.
When does the investment pay off?
With regular consumption usually within a few years, and often sooner for laser cutting. Based on your current consumption and gas price, we prepare a payback calculation.
What purity do I really need?
95–99% is enough for inerting and tyres, 99.5–99.9% for food, and 99.99% or more for laser cutting stainless steel and electronics. Each step up in purity needs more air, so specifying it precisely matters for costs.
What additional equipment is required?
A compressor, dryer and compressed air filtration, an air receiver and a nitrogen product receiver. If needed, also a booster and high-pressure storage. We supply the complete system.
How much maintenance is needed?
Regular filter changes and an annual inspection. The molecular sieve has a long service life. Our technicians handle service, commissioning and purity measurements.
