Nitrogen generation system from the Nordson Corp. creates a continuous, uninterrupted supply of 95 to 99.5 percent pure nitrogen gas. As a replacement for nitrogen gas cylinders, system enhances operation of many Nordson adhesive dispensing systems. The inert nitrogen gas can be used with Nordson foaming systems to produce a closed cell foam that improves physical properties and reduces the volume of adhesives and sealants and with most Nordson tank melters or extruders to create a nitrogen blanket to preserve reactive material integrity. As a self-contained, wall-mount system, the generator installs without electrical connections, according to the company. (800) 683-2314. Nordson.com/adhesive.
