Our gas generators are specifically designed in compliance with the highest quality standards to provide a safe and continuous gas supply focusing on meeting customers’ requirements.
Onsigen generators use the pressure swing adsorption process (PSA process). It is used to separate Oxygen molecules from the air – Oxygen generators or Nitrogen molecules from the air – Nitrogen generators.
When the pressure is lowered, the gas is adsorbed and released into the exhaust.
Onsigen basically uses two adsorbent vessels that allow near-continuous production of the required gas. It also permits pressure equalization, where the gas leaving the vessel which is being depressurized is used to partially pressurize the second vessel. This results in significant energy savings and also prolongs the lifetime of the adsorbent.

Medical oxygen in hospitals is essential. It is used in surgeries, in cases with acute conditions, for regeneration purposes and several other cases. The demand for oxygen, PSA oxygen generators is growing, as this variant is significantly cheaper than the use of liquid oxygen.
Oxygen is as important to fish as it is to any living creature, therefore lots of oxygen generators are used in the breeding, transport and storage of live fish.
Ozone is very often used in wastewater treatment. To increase the efficiency of the ozone generator, the use of oxygen is required, which reaches the desired dew point and reduces the consumption of the
ozone generator.
Nitrogen is used by numerous
companies to pack their products in a protective atmosphere, such as packaging, bottling, fruit storage, etc. – preventing access to oxygen.
With fire and explosions being a continuous health and safety risk, the creation of a non-flammable environment is a crucial task. By enabling generators to produce the correct purity and amount of N2, blanketing and purging of numerous tank and pipe types, a non-flammable environment is created and the health and safety issue is resolved. Several other uses for N2 along with O2 are found in these industries.
In nitrogen laser cutting, the beam penetrates the material and thereafter nitrogen, which causes the material to harden faster. This method produces a very high-quality cut surface with low roughness and without oxide coating. In oxygen laser cutting, oxygen is blown to the cutting point, it then reacts with the carbon in the steel with an exothermic reaction and takes part in the melting of other material.
In this method, higher cutting speeds are achieved but thin oxide layers can be found in the cut.
Directly supplied oxygen increases the level of soluble oxygen in the
leaching process during gold mining. This increases overall productivity and also reduces total costs. The oxygen system can be installed right next to the leaching towers, excluding the costly transport of liquid oxygen.
Inert gas must be present on chemical, oil or oil tankers at all times, due to a possibility of a fire generated during pumping. Nitrogen is used for this purpose, which the customer is able to produce directly on board.
The Oxygen generator is composed of two separation vessels filled with molecular sieve adsorbers (Zeolite). As clean and dried compressed air pressurizes one vessel, the nitrogen becomes retained by the molecular sieve and the oxygen goes straight to the oxygen buffer. Once the vessel approached nitrogen saturation, the process switches to the second vessel and the adsorbed nitrogen in the first vessel are released into the ambient air.
Oxygen from 1.5 Nm3/h to 180 Nm3/h with purities up to 95%
The nitrogen generator is also composed of two separation vessels, but is filled with a carbon molecular sieve (CMS) oxygen is adsorbed in the molecular sieve and Nitrogen is passing through CMS to the nitrogen buffer.
Nitrogen from 1.4 Nm3/h to 2112 Nm3/h with purities up to 99.999%
