ROI - Return of Investment



The Return of Investment or ROI is a figure giving calculating how long it will take for an investment to be paid back.
For instance when purchasing a machine for 100,000 this machine will be used in production and can produce new goods.
If the machine will produce goods will give a profit of 5,000 per month, then the ROI is calculated as follows:
100,000 Investment / 5,000 profit = Return on Investment of 20 month.
In the case of Pursanova TM , the ROI depends on the kind of application. Having a freshwater generator, which is treated today chemically and despite this has to be cleaned every 3 month, is then treated by a Pursanova DiskTM , the user will save, the chemicals for treating the seawater as well as the effort of cleaing the machine. This gives for a Fresh Water Generator normally a ROI of 3 to 6 month.
