  4. Operating system:
    10 pre-programmed regimes of temperature management . Automatic ignition management. All production processes are controlled on screencomputer.
  5. Air cooling, air cooling system management.
  6. The quality and performance.
  7. No pollution, no emissions.
  8. Early warning system:
    Emergency gas valve is activated automatically when the gas pressure reaches extreme high or low standards. The system warns and stops accessory power. Prevention and control of temperature automatically. The system also prevents any leaking gas.
