|Data may change without notice. Conversion rate depends on methane content and assumed to be 1/10 of the kW of gas consumed. Heat recovery: Heating water temperature = 90°C outlet flow, max 70°C return flow. Tailored heat recovery available. Rating Conditions: Combustion air/Ambient temperature 27 °C; rated altitude max. 300 m; methane content >76%. Exhaust gas emissions for Lambda 1 Engines: NOx < 250 mg/Nm³ / CO < 300 mg/Nm³. Exhaust gas emissions for Lean burn engines: NOx < 500 mg/Nm³ / CO < 300 mg/Nm³. (adjustment to 250 mg NOx possible, with decreased electric efficiency).
