The molecular sieve for nitrogen generation and oxygen generation essentially differ from each other.
Nitrogen is filtered from the compressed air with the help of activated carbon, while oxygen is produced with so-called zeolites. INMATEC ensures the highest possible quality of the respective filter materials here.
Not all molecular sieves are equal. Even within some manufacturers, differences exist, e.g. depending on the place of production, size and quality.
If you obtain your molecular sieve from INMATEC, you have the greatest assurance that the most suitable model, appropriate for your INMATEC system, is being used.

Since 01 April 2011, the European Pharmacopoeia Standard allows the use of oxygen with 93.0% purity.

An oxygen concentrator is understood as small medical systems for home use. The term oxygen generator indicates systems on a larger scale.

PSA nitrogen generators and PSA oxygen generators from INMATEC are suitable both for installation inside and outside. It is decisive that the ambient temperature is between +5°C and +45°C.

If the generator is operated at higher air humidity, it is advisable to continually measure the compressed air humidity and regulate this if necessary. The INMATEC engineers are happy to advise you.

With the daily 24-hour operation, we recommend that the elements of the internal filter are replaced in six month intervals. The valves should generally be replaced every five years. The service work for the compressors are based on the recommendations of the manufacturer.

Generally, the performance of the molecular sieve is reduced in the event of contamination. It should be replaced in the event of contamination. Oil and ammonia are frequent contaminating substances. If the molecular sieve is soiled with water, the need for replacement depends on the degree of soiling. If it is low, the sieve can usually remain in operation.
Tip: Ask the INMATEC engineers in advance which additional arrangements may be practical, in order to ensure the smoothest possible functioning of the molecular sieve.

Molecular serves can always be replaced on site as the generator, which keeps the time and cost necessary for replacement low. The exact costs for the replacement depend on the size and model of the generator.

Provided the necessary quality of intake air or compressed air is met, a standard compressor is fully satisfactory. In must be ensured that the compressor power is adapted to the power of the nitrogen generator or oxygen generator.

Yes, oil-free compressors are generally significantly more expensive than oil lubricated devices. The oil filter is omitted for this, which would otherwise need to be connected in order to ensure oil-free compressed air.

This depends on the quality of the intake air. With a PSA nitrogen generator or a PSA oxygen generator, the pressure thaw point must not be higher than +4°C. At higher values, a dryer is necessary.

In principle, an adsorption dryer can be used instead of a refrigeration dryer. Generally, the performance of the nitrogen generators/oxygen generators increases slightly through this. On the other hand, there are higher costs and a larger energy cost, which cancels the performance advantage.

The size of the air compressor for a PSA generator is based on the height of the installation location. The higher this is above the sea level, the larger the compressor must be in order to balance the decreasing air pressure.

The pressure thaw point of the oxygen produced by the PSA oxygen generator is between -51°C and -73°C, depending on the size of the generator.

No, all models have the same starting pressure.

No, the entire nitrogen/oxygen produced by a PSA nitrogen generator/PSA oxygen generator is available without loss.

Ideally, data is available for determining the appropriate unit size for customers. The use of a user history is also helpful. In other cases, the peak demand can be determined by a formula. INMATEC is happy to answer further questions.

INMATEC fits its nitrogen generators and oxygen generators by series with a remote monitoring system. For this reason, we can access your device at any time where needed, in order to make diagnoses or remedy faults.

Due to faulty handling, nitrogen cylinders and oxygen cylinders can become soiled. For this reason, INMATEC offers vacuum pumps for all models, in order to empty every cylinder before it is refilled.

There is no rule of this kind. If the cylinder was under the supervision of the filler during the entire usage period, emptying with a vacuum pump is not necessary. In other cases, INMATEC advises that every cylinder is emptied with a vacuum pump before it is refilled.

With PSA nitrogen generators, the costs for the nitrogen production and for filling cylinders is normally given in kilowatt-hours (kW/h). The reason for this is that while the air is free, there are costs for the electricity to operate the air compressor. When operating the system at sea level, approximately 10 kW/h is necessary in order to fill a 10m³ nitrogen cylinder – or in other words: 0.5 kW/h per m³. The costs for filling oxygen cylinders are subject to the same calculations.

Most INMATEC systems are designed so that they can fit without problems in a standard 20 or 40 foot container. There they are also particularly safely protected from any transport damage.

Each nitrogen generator or oxygen generator leaves our factory only after passing intensive functional tests. This also includes a 24-hour continual operation.
