WHAT IS NITROTHERM? A new spray painting method that allows working with an inert fluid, at lower pressures and at a constant temperature It has significant advantages in terms of savings, productivity, quality and respect for the environment NITROGEN Is the chemical element that has the atomic number 7 The molecular nitrogen is a colourless, odourless, tasteless and inert gas constituting 78% of volume of Earth’s atmosphere (is the most widely spread gas in the air) Nitro System srl, via Cinque Giornate 76C, 22012, Cernobbio (CO) PI-CF 03347050134 www.nitro-system.com, info@nitro-system.com
PRODUCTION OF NITROGEN The polymeric membrane (“molecular discriminator”) of Nitrotherm uses 3 principles to separate the nitrogen enriched flow from the compressed air: hollow fibres : the most advantageous geometrical form for membrane processes (large density of filtering surface, low energy consumption) selective permeation : each gas has a characteristic permeation rate that is its ability to dissolve and diffuse through a membrane. It is therefore possible to separate gases such oxygen, helium, water vapour (permeated) from nitrogen, argon (concentrated) tangent flow : avoids the accumulation of permeated molecules, the membrane is not subject to progressive contamination since the exhaust gases are eliminated at atmospheric pressure Nitro System srl, via Cinque Giornate 76C, 22012, Cernobbio (CO) PI-CF 03347050134 www.nitro-system.com, info@nitro-system.com
WHY NITROGEN With NitrothermSpray can effectively control the two key variables of the process of painting: Temperature Fluid TEMPERATURE The NitrothermSpray heating system is inside the Nitrotherm Tube and controlled at the end of it with a thermocouple Temperature and humidity do not affect anymore the painting process Nitro System srl, via Cinque Giornate 76C, 22012, Cernobbio (CO) PI-CF 03347050134 www.nitro-system.com, info@nitro-system.com
WHY NITROGEN FLUID Nitrogen is anhydrous and without impurities (dust, oil, fumes, chemical contaminants, humidity*) The particles of paint with nitrogenas a carrier are faster (13 m/s) than air (7m/s): less pressure** The particles of paint with nitrogenas a carrier are smaller (35µm3) than the ones of the air (41µm3): low values = better evaporation on surface and better atomization of sprayed products** * A residue of humidity can be lefu for the process of retjculatjon **PNR Italia Srl, a company successfully manufacturing industrial atomizers and supplying liquid atomizatjon based systems since 1968, studied and compared the cone produced with compressed air and nitrogen with a Laser Test Nitro System srl, via Cinque Giornate 76C, 22012, Cernobbio (CO) PI-CF 03347050134 www.nitro-system.com, info@nitro-system.com
ELECTROSTATIC PROPERTIES acetate It is possible to charge nitrogen with positive or negative ions and regulate the charge quantity (up to glass 15 kV) nylon aluminium The destatic version makes work easier either during paper the application (metallic products) or at the end of the neutral COTTON process (drastic reduction of impurities on the sheet) steel wood Is recommended especially for polymers painting polyester polyurethane polyethylene polypropylene Triboelectric series Notjce: NITROTHERM does not replace electrostatjc applicatjons nor does it permanently solve problems cause by statjcity Nitro System srl, via Cinque Giornate 76C, 22012, Cernobbio (CO) PI-CF 03347050134 www.nitro-system.com, info@nitro-system.com
