Once you place the DynamOx unit into full production, you will quickly determine that the cost of oxygen can be substantial.  For that reason DynamOx offers to sell an oxygen generating unit that is fully integrated into the DynamOx control system.  At many DynamOx locations, we have determined that the cost of gaseous oxygen can exceed $0.35 / #.  Liquid Oxygen can be provided about $0.15 / # plus the rental of the storage tank at approximately $300 / month.  The variable costs of oxygen generation is below $0.05 / pound (operations and maintenance) but the capital cost is substantial ($45,000+/-).  Assuming the equipment is purchased (and financed at Zero Down, 7% over five years) the monthly capital cost would be $990.  To aid you with your review, we offer the following.
