No inpurity should be in the gas. Water in the gas should be less than 20g/Nm3.4. Heat value should be at least 8500kcal/m3, if less than this value, the power of the engine will be declined.5. Gas pressure should be 3-100KPa, if the pressure is less than 3KPa, booster fan is necessary.6.The gas should be dehydrated and desulfurated. Make sure that there is no liquid in the gas. H2S<200mg/Nm3CONTROL PANELControl panel is panel type, vertical structure, model is GPL700. Control panel is equipped with meters showing various parameters of operating status, automatic air switch and timer. All of the electric cells possess three-proof functions.The Generator possesses the following automatic monitoring and protective functions:A) Audio or visual alarm for:- High oil and water temperature- Low oil pressure- Over current- Short circuit- Over-speed- Reverse powerB) Shut-off for:- Low oil pressure- Over-speed- Short circuit- Over-speed- Reverse powerC) Trip-off for:- Over-current- Short circuit- Reverse powerThe generator can not only supply power directly to load but also can be paralleled running.OPTIONAL DEVICESteel Soundproof Container (sound attenuated canopy)CHP/ Cogeneration/CCHP TrigenerationATS and Synchronization Parallelling PanelOil and Water Heater
