Unmatched Performance
Nitrosave consists of the oxygen monitor/control unit and a proportional or other control valve which is fitted into the nitrogen supply line to the machine.
Nitrosave monitors the residual oxygen in the system under control using our latest cell technology. The oxygen measurement is then used together with a fuzzy logic control algorithm and user-defined setpoints for desired oxygen level, to automatically control the
opening of the valve, which regulates the flow of nitrogen into the machine.
This ensures enough nitrogen to comfortably maintain the desired oxygen level is fed into the machine but eliminates the waste seen with fixed-flow nitrogen systems.
Installation of the Nitrosave is very simple and it can be retrofitted to almost all types of machines.
