FOR INDUSTRIAL APPLICATIONS Nitrogen is a gas used increasingly in industrial applications. Tangible evidence and the construction of hundreds of plants confirm that on-site nitrogen self-production is a convenient solution both from an economic point of view and from a practical one, strictly related to user safety. As we know, nitrogen is an inert gas, used to eliminate oxygen and other unwanted gases. It is therefore generally used in industrial applications to prevent oxidation in metals, inhibit bacteriological growth in food and pharmaceuticals, and minimise the risk of spontaneous...

SUPERIOR PERFORMANCE WITH GUARANTEED RESULTS advantages of on-site nitrogen production compared to cylinders and liquid specific advantages of claind generators compared to those of competitors autonomy and production continuity reliability, long life and low maintenance costs quick payback a wide range that meets all customer requirements production of nitrogen proportional to consumption thanks to the stand-by mode no logistical problems and elimination of administrative activities related to continuous gas supply digital control system that can be interfaced with company IT systems (e.g....

TO PRODUCE NITROGEN Claind’s solutions for nitrogen self-production use PSA (Pressure Swing Adsorption) technology. The PSA system consists of two beds of molecular CMS sieves (Carbon Molecular Sieve), which are alternatively pressurised and depressurised. Each bed can consist of one or more columns. The compressed air, which is pretreated to eliminate dust and moisture, enters the base of the first active bed and flows through the CMS. Oxygen, carbon dioxide and other pollutants in the air are trapped, while nitrogen flows through the bed and exits from the head of the column towards a...

SIGNIFICANT BUSINESS CASES metallurgy, heat treatments and welding Heat treatment for metals is a process that involves conferring certain properties to metals (such as copper, aluminium, carbon and stainless steels): heat treatment cycles are carried out inside furnaces in controlled atmospheres. Metal sensitivity to oxygen greatly increases with high temperatures, e.g. in quenching, cementation, annealing or nitriding processes. A similar situation happens in metal welding. Nitrogen, as an inert gas, performs the task of inhibiting oxidation and optimising the quality of the process. The...

Nitrogen is used in this sector to make systems safe from fire and explosions, particularly in the applications of: inerting fuel storage tanks, oil and natural gas extraction, maintenance of oil and gas pipelines. Nitrogen is used even in moulding plastics as an assist gas: plastic product manufacture requires a pressurised gas that does not react with the material and averts mechanical stress, ensuring greater rigidity, less distortion and an optimal structure.

In wave and selective soldering machines or in reflow ovens, the alloys used in producing electronic boards are subject to oxidation; using nitrogen as an inert gas during soldering prevents this process and ensures better product quality. Nitrogen must reach the EU qualification of “food additive E941” in the food industry. In this field, nitrogen is used for packaging perishables in a protected atmosphere, prolonging their shelf life, maintaining the organoleptic properties of the food unaltered, preserving its freshness and guaranteeing better presentability in terms of colour, shape and...

laser cutting Nitrogen is also used in sheet metal processing as a laser cutting assist gas: nitrogen’s inert properties and flow pressure guarantee a shiny edge and allow the removal of any burrs to obtain a quality cutting profile.

OUR RANGE OF GENERATORS DESIGNED TO FULFILL ALL YOUR NEEDS FLO, PICO, MAXI and DOMINUS NL SERIES The nitrogen generators of the FLO, PICO, MAXI and DOMINUS NL series consist of a large number of models, whose nitrogen flow rates differ according to the required purity. outgoing nitrogen flow rate* * The hourly flow rates refer to nominal inlet air conditions: pressure of 8.5 bar (123.3 psi), CMS temperature of 20°C (68°F). ** Nitrogen purity expressed in oxygen content.

instrumental features: Scan this QR code and discover more about DOMINUS NL high-sensitivity oxygen analyser: fitted as standard to allow real-time monitoring of the purity, enabling the generator to self-adjust the process to maintain a constant degree of purity. digital control system: the MODBUS protocol allows the generator to be interfaced with company IT systems (e.g. PLC or SCADA), while the MQTTS protocol allows connection to the Claind4You web portal for remote control in autonomy and safety. single nitrogen storage tank: for the operation and storage of the nitrogen produced, with...

Due to their excellent capacities, all Claind generators, but particularly those in the maxi and dominus nl series, can easily be associated with Booster or HP compressors to increase the nitrogen pressure to the levels required by the client. This makes them able to exploit the efficiency and reliability of the products, offering a safe, concrete solution for all applications using nitrogen at medium and high pressure, particularly for laser cutting sheet metal. Claind’s approach exploits the generators integrablity, assuring full downstream flexibility in terms of: capacities: different...
