HIGH PURITY NITROGEN GENERATORS High purity nitrogen generators "SATURN" ERREDUE's HIGH PURITY nitrogen generators produce a continuous flow of "nitrogen gas" that is dry and oxygen free, directly from the filtration and separation of compressed air. The idea behind this ErreDue new machine was born from hydrogen applications, in which ErreDue has extensive experience as an hydrogen generator manufacturer. The principle is to purify the nitrogen gas by adding a small amount of hydrogen (0.5-1%). Any nitrogen gas, supplied in cylinders, liquid tank or by generation, contains oxygen molecules as an impurity. The hydrogen molecules combine with oxygen molecules to be transformed into water by chemical reaction, the water vapour is then eliminated by a filtration device in the machine. NITROGEN AND OXYGEN GENERATORS Nitrogen generators and oxygen generators operate with the principle ERREDUE PSA (pressure swing absorption) to produce a constant flow of nitrogen or oxygen from compressed air filtration: remind that air is composed of 78% nitrogen , for 20.8% of oxygen the rest by traces of other gases (argon, helium, hydrogen ...). The system is made up by two sets of aluminum extruded columns that are filled with "CMS" (Carbon Molecular Sieves) to produce nitrogen or "Zeolites" to produce oxygen. These materials have physical features such as to permit a mechanical-holding of oxygen molecules for CMS sieves or to hold nitrogen molecules for zeolites sieves. A stream of compressed and pre-treated air crosses the columns from the bottom to the top. The oxygen or nitrogen is absorbed by the filtering material, whereas nitrogen or oxygen outgoing from the top of the towers is collected in a storage tank and ready to be used. The PLC control system and dedicated software, developed by ERREDUE, automatically runs the main functions of production process of nitrogen gas or oxygen gas. A series of columns is kept in operation for a predetermined period of time, and when it is almost saturated by absorbed gases, the control system automatically activates the other set of columns that was being regenerate, and the contents of the first series is then purged into free air and then the filtering material is regenerated. The production system consists of a double sets of columns that allows an easily extension by adding further columns and consequent increase of gas production. The purity of nitrogen is up to 99.995% and 98% for the oxygen gas. HYDROGEN GENERATORS Hydrogen generators Erre Due Gas generators produces Hydrogen and Oxygen perfectly separated The ErreDue generator produces hydrogen and oxygen perfectly separated from each other using electrolytic dissociation of water molecule: the generator needs for its functioning only demineralized water and electricity supply. HYDROGEN GENERATORS Hydrogen generators Erre Due Gas generators produces Hydrogen and Oxygen perfectly separated The ErreDue generator produces hydrogen and oxygen perfectly separated from each other using electrolytic dissociation of water molecule: the generator needs for its functioning only demineralized water and electricity supply. The gas is produced directly at the required pressure (up to 30 bar) and with quality characteristics which make it for immediate use for most applications. When gas is requested at very high purity quality a downstream purifying equipment, or integrated in the generator provides the right and needed features. The safety and, ecology, the guaranteed quality of produced gas and the low operating costs, along with many other features make it definitely a machine's cutting-edge technology Nitrogen and oxygen generators Nitrogen generators and oxygen generators operate with the principle ERREDUE PSA (pressure swing absorption) to produce a constant flow of nitrogen or oxygen from compressed air filtration: remind that air is composed of 78% nitrogen , for 20.8% of oxygen the rest by traces of other gases (argon, helium, hydrogen High purity nitrogen generators High purity nitrogen generators "SATURN" ERREDUE's HIGH PURITY nitrogen generators produce a continuous flow of 'nitrogen gas' that is dry and oxygen free, directly from the filtration and separation of compressed air.

HIGH PURITY NITROGEN GENERATORS PURITY UP TO 99,9999% Applications: Pharmaceutical industry About ErreDue Erredue's mission is the manufacture and sale of machinery for self-production of high purity technical gases on site. Our range of machines covers the needs of gas production for small laboratory needs and for large industrial companies, the versatility and adaptability of our generators allows us to be the ideal partner for any production. Our water based generators can produce, by an electrolytic process, high purity hydrogen and oxygen gas (up to 99.9999% pure) for all your needs, with capacities ranging from just a few litres per hour up to several hundred cubic meters/h and at any required pressure. Hydrogen generators Mercury Erre Due Gas generators produces Hydrogen and Oxygen perfectly separated from each other More info Our air based molecular sieve generators produce nitrogen gas from standard quality (98% purity) to very high purity (up to 99.9999% pure) for all your requirements with capacities from just a few litres per hour up thousands of mc/h and at any required pressure. ErreDue'sHigh purity nitrogen generators "SATURN"produce a continuous flow of "nitrogen gas" that is dry and oxygen free More info Ecology Elimination of CO2 emissions into the atmosphere and energy savings by avoiding gas transportation from the producer to consumer. Elimination of CO2 emissions, the hydrogen produced at low-cost by ErreDue Spa generators, has replaced many polluting combustible gases. Energy saving, since the gas is produced directly at the required pressure it is much lower than that of cylinder packs. Environmental sustainability because the hydrogen that is ecologically produced by ErreDue Spa generators is used in the production of green energy as an energy source (e.g. hydrogen fuel cells) and can be stored locally. Safety The risk of accident is reduced since the gas is produced directly on site at the required pressure, plus there is a total elimination of any risk connected with the transport and handling of compressed gases. The company ErreDue spa, provides an after-sales service that starts from the commissioning of the plant and end with the gas supply to the usage. We take care of customer satisfaction ensuring the right amount and purity of gas required by the application. Furthermore we provide specific contracts for routine maintenance, and extraordinary repairs. The company ErreDue Spa provides plants "turnkey" taking care of all the steps, from design to after-sales service. Plant engineering solutions are Customized and studied according to the needs of the application and the productive structure of the end user. The ErreDue company provides to his customers highly skilled and well trained technicians with years of experience. We pay great effort in customer care from installation to start-up of the plant and instructing the customer staff on using hydrogen, nitrogen and oxygen generators. We also provide the possibility to test the plant directly in our factory.
