8500/9500 Nitrosave Oxygen Control System Save up to 50% in nitrogen running costs with the Nitrosave oxygen control system Curing ovens & furnaces Flow soldering Glove boxes Food packaging lines Nitrogen purge systems Features & Benefits Save on nitrogen usage and rework Nitrosave Viewer PC software makes costs. set up quick and easy. Improve process control and product USB and RS485 communications quality. output for data logging can document the whole process. Automatically detects a halt in production and reduces nitrogen flow Small footprint allows OEM for even greater savings. manufacturers to install inside their machines. Extremely fast response time even after high oxygen exursions means quicker process optimisation. Conforms to European Directives: Electromagnetic Compatibility Directive 2004/108/EC Low Voltage Directive 73/23/EEC Save Nitrogen and Improve Process Control Nitrosave Technologies Nitrogen is used in soldering and other controlled The Nitrosave oxygen control system can be easily Nitrosave consists of the Depending on your application atmosphere machines to remove oxygen which transferred to other inerted machines. Whether you oxygen monitor/control unit requirement there are 2 results in better production quality, however, nitrogen have a small wave machine or large reflow system, and a proportional or other technologies to choose from; can be expensive. the savings with Nitrosave are considerable. With control valve which is fitted the 8500 zirconia cell or the nitrogen reductions of up to 50%, the payback time into the nitrogen supply line to 9500 electrochemical cell. Systech Illinois’ long expertise in the field of Gas for the system is very short, with the added benefits the machine. Analysis led to the development (in partnership with of improvements in process control and full major soldering machine manufacturers) of the traceability. Principle of Operation Nitrosave monitors the Nitrosave, designed to reduce the nitrogen residual oxygen in the system consumption of your machine. under control using Systech The 8500 oxygen detection cell Illinois’ latest cell technology. is a high purity, high density, The oxygen measurement is Reflow Zone O stabilised zirconia ceramic. 2 then used together with a Measurement The sensor produces a voltage fuzzy logic control algorithm signal relative to the oxygen and user-defined set points concentration of the sample for desired oxygen level, to gas stream. The cell’s automatically control the logarithmic output is converted opening of the valve, which and linearised by a high speed regulates the flow of nitrogen microprocessor to provide a Control Valve into the machine. direct digital readout on the Reflow M/C instrument’s LED display. This ensures enough nitrogen to comfortably maintain the The 9500 uses the patented Control S Signal desired oxygen level is fed RACE sensor*. A unique into the machine but N N2 electrochemical cell which 2 eliminates the waste seen responds in seconds even to with fixed-flow nitrogen large changes in oxygen levels systems. and is unaffected by solvent vapours or hydrocarbons Installation of the Nitrosave is making it ideal for use in very simple and it can be Control Valves Operator Interface systems where high oxygen retrofitted to almost all types events are common. of machines.

Control configuration made across the full range control system is straight Read only mode normally found in a soldering forward and can be done oven, without delays due to the when the machine is in Outputs & Alarm purging of the measurement Nitrosave Viewer production. It is always system or sample lines. possible to revert to manual For data logging, chart recorders and remote The high speed of the cell Datalogging is simple with the provided Nitrosave control and the system monitoring ensures a very rapid start Viewer program. This allows a log of a number of will automatically select USB and RS485 up response and accurate machine parameters (including oxygen level and maximum flow in the event of monitoring of changes in the 4-20mA/0-20mA valve opening) to be made.

The RACETM sensor has a 3 year limited guarantee, is Doping Systems maintenance-free and requires Photoswitch PCB Detector infrequent calibration. Mass Flow controlled, or other, doping for control at Automatically detects a halt in production and high oxygen levels (500ppm+). Ideal when soldering reduces nitrogen flow for even greater savings. * UK Patent no. 2324870 BGA components.
