Special statement： 1、 The technical data are based on natural gas with a calorific value of 10 kWh/Nm³ and a methane no. > 90% 2、 The technical data indicated is based on standard conditions according to ISO8528/1, ISO3046/1 and BS5514/1 3、 The technical data is measured in standard conditions: Absolute atmospheric pressure：100kPa Ambient temperature：25°C Relative air humidity：30% 4、 Rating adaptation at ambient conditions according to DIN ISO 3046/1.The tolerance for the specific fuel consumption is + 5 % at rated output. 5、 Dimension and weight above are just for standard product and may be subject to change. As this document is used only for presale reference, take the specification supplied by Smart Action before ordering as final. 6、 The applicable ambient temperature is -30 ° C ~ 50 ° C; when the ambient temperature exceeds 40 ° C, the rated power is reduced by 3% for every 5 ° C increase in temperature. Applicable altitude is less than 3000 meters; when the altitude exceeds 500 meters, the rated power is reduced by 5% for every 500 meters of height.
