Nitrogen Generators

Nitrogen Generator APPLICATION APPLICATION Nitrogen and Nitrogen mixturers are used n various areas of industry to improve the quality or shelf lige of a product or to prevent a reaction with oxygen. Nitrogen generated on site can be produced cost-effectively by using the already existing compressed air station. In this process nitrogen is available at all times and replaces the expensive supply through cylinder bundles or from tanks with liquid gas, which also require complex logistics and safety measures. These problems can be avoided cost-effectively with a nitrogen generator. They...

Nitrogen Generators COST FACTOR NITROGEN ADVANTAGES OF OWN GENERATION The conventional nitrogen supply from high-pressure cylinders or liquid gas tanks is expensive, time-consuming and requires a certain amount of advance planning and logistics. In-house production using nitrogen generators can reduce costs and in-house effort by a considerable amount and thus ofers great saving potentials, combined with an independent future of your gas supply. COSTS OF DIFFERENT NITROGEN SOURCES Source Single cylinders bundled cylinders liquid nitrogen *1 The values indicated in this table are average...

Nitrogen Generators NITROGEN PURITY WHY PRODUCE NITROGEN ON SITE? Nitrogen is an mayor component of our ambient air. It is therefore always available and free of charge. However, the available concentration is usually not sufficient for many applications. Oxygen, argon and other noble gases influence the quality of use. Especially oxygen has a decisive influence on many applications, particularly with regards to oxidation and shelf life. Especially in the food industry, oxygen is an undesirable component during packaging, as the shelf life of the food is reduced accordingly. In industrial...

Nitrogen Generators OUR PORTFOLIO WHICH GENERATOR TYPES ARE AVAILABLE? FST offers a wide portfolio of nitrogen generators. Depending on the volume and the required nitrogen purity so-called membrane systems or PSA system are available. Membrane systems use the principle of selective permeation. Membrane generators are used with nitrogen purities of up to 99,5 % and can produce almost any amount of nitrogen. PSA generators are the second type of nitrogen generators. The name is derived from their mode of operation in which the compressed air is fed through a vessel filled with CMS...

Oxygen sensor included for guaranteeed purity of nitrogen according to the design conditions. Siemens S7 control with touchscreen display controls the necessary components. Data logger and modbus TCP comunication already included. Large cross flow sections reduce the differential pressure. Stainless steel piping for durable, corrosion-free operation. Switching between the vessels is done via individually controlled valves. Free accessible valves and thus simplified maintenance.

Nitorgen generators of the GNA series operate according to the pressure swing adsorptin(PSA) principle. The incoming compressed air is fed into the first vessel. The oxygen is bound in the CMS desiccant so that only pure nitrogen leaves the generator. As soon as the desiccant is daturated, e.g. the oxygen content at the outlet increases, the system switches to the second vessel. The first vessel is expanded to atmospheric pressure and the bounded oxygen is discharged to the environment. For a continuus operation of a PSA system, two vessels are required. molsieve protection flow sensor...

C5 control with touch screen to control and monitor all components. Plug-and-play. Simply connect and start-up. Easy maintenance. Filter and flow regulator included. Silent operation mode. Pure nitrogen without interruption.

The various components contained in the air, e.g. oxygen, carbon dioxide, water vapour, nitrogen and other noble gases, are fed into the membrane. Due to their different molecular structure, they diffuse through the hollow fibres membrane at different speeds. Nitrogen has a low diffusion rate and accumulates within the membrane. The purity of the gas is dtermined by the flow rate. The required nitrogen purity can be adjusted by varying the pressure and flow. The performance of a GNM nitrogen generator can be improved by several options, e.g. • flow regulator membrane protection energy...
