1st mistake is the wrong choice of concentration.
The most common mistake is the one that you have to pay a lot of money for, because if you are not responsible for the choice of this parameter, the range of prices can be quite large. For example, a nitrogen generator with a capacity of 30m³/hour and a concentration of 99.999 will cost 50% more than a generator of the same capacity with a concentration of 99.9%.
How to avoid? - It is necessary to study carefully the materials of the final equipment (consumer) or to contact competent engineers.
2nd mistake - the capacity is not accurately calculated.
The second important parameter of the station is its capacity, this parameter should be chosen with a small excess of 5 to 10%. If you choose it close to the actual consumption, any short-term excess may lead to a decrease in gas concentration.
How to avoid it? - The most correct way is a physical measurement of the gas consumption, but if this is not possible, then use special calculators or formulas to calculate it.
3rd mistake is not taking into account operating conditions
Another important point to consider is the future operating conditions of the station. For adsorption stations, an important environmental parameter is temperature, if its value will exceed the passport data of 104 degress Fahrenheit, the performance of the station will gradually decrease. If during operation the temperature drops below 5 degress Fahrenheit, there is a risk of condensation of droplets of moisture on the internal surface of the adsorbers, resulting in damage to the molecular sieve.
How to avoid? - Provide and maintain the required operating conditions or choose a special version of the generator.
4th mistake is an individual choice of compressor.
The nature of compressed air consumption in adsorption generators is quite complex and cyclic. Many factors must be taken into account for the correct operation of the system: the nature of consumption, the number of peak loads, additional losses of compressed air, the volume of receivers and much more.
Opinion of incompetent engineers, saying that the use of a frequency converter in the compressor will help save energy, in most cases it is a waste of money.
How to avoid it? - Trust this work to a competent engineer.
5th mistake is to select the equipment based on price.
Many people compare equipment solely on the basis of cost, but if you go deeper into the technical parameters and design, you can see a significant difference. The cost of generators depends on the quality of used components, adsorbent and automation level. The service life of budget stations is often not more than 3 years, and requires expensive repairs with the replacement of the molecular sieve.
How to avoid? - Choose quality equipment by comparing the components: valves used, adsorbent, automation system.
