GAS FLOW CONTROLLER KD 500-1A MAPY Electronic flow control system for modified atmospheres for flowwrap machines in the food industry and for room atmospheres e.g. for the storage of fruit and vegetables. Cost Reduction • saves up to 30% of gas consumption by automatic controlling the required residual oxygen level to a pre determined set point • the non-destructive gas analysis guarantees quality of the packages and economy of the production Easy Operation • simple calibration • easy to read display • integrated data logger • USB connection for file transfer • administration of product names • simple to operate via touch-screen • ethernet connection for network integration • measured data storage • user level with different access authorisation • user definable settings for each different product i.e. set point, alarm limits etc. High Process Reliability • electronic control of the sample gas to the sensor • lockable transparent door for protection of settings • alarm signals are given if the set limits are exceeded and a potential free contact operates to e.g. autostop your machine to avoid quality problems • independent of pressure fluctuations in the gas supply • independent of packing speeds (MAP) • independent of package sizes (MAP) Maximum Hygiene • splash-proof, robust stainless steel housing • smooth and easy to clean surface • Interfaces for the documentation and remote transfer of the settings and measured values • software GASCONTROL CENTER for recording of results (see separate data sheet) • fully automatic calibration • bar code scanner for product names or user selection • additional memory • sample measurement via needle - also with additional sensor Please identify the individual gases and control ranges of flow at the time of enquiring!
