At IVF-KTH in Stockholm we run our Sinterstation 2000 with a nitrogen
generator from Dominick Hunter, without any problems. We had the generator
installed 1995, before that we run the Sinterstation with bottled nitrogen.
The generator separates the nitrogen from compressed air using a carbon
molecular sieve - Pressure Swing Adsorption (PSA).
Our generator is dimensioned so that it can produce 3,2 normal cubic meters
per hour at a purity of 99,9%. This flow is about twice as much as the
Sinterstation needs when it is up and running producing parts. Although
during purge (evacuating the chamber) a flow of about 8,0 normal cubic
meters per hour is needed for about 20 minutes - for that we help the
generator with bottled nitrogen, which also serves as a backup.
The nitrogen generator cost us about $5.000/year and that includes
everything (we lease the equipment from Dominick Hunters representative in
Sweden).
