Genset de-ratingAltitude and temperature derate multiplication factor Barometer Air filter inlet temperature Based on SAE standard ambient pressure vs. altitude. Assumes LT return temperature is 10 °C above air filter inlet. 1. Determine derate multiplier vs. temperature and altitude in Table A depending upon your operating condition. 2. Assumes the LT return temperature is 10°C above the air filter inlet with a maximum LT temperature of 50°C. 3. If the LT temperature exceeds 50°C, consult factory for recommendations. 4. Altitude is based upon SAE standard ambient pressure vs. altitude. For low...

Heat rejection factor (altitude and ambient) for HT and LT circuits Barometer Air filter inlet temperature LT & HT circuit heat rejection calculation 1. Determine derate multiplier vs. temperature derate per Table A. 2. Using the multiplier from #1 in Table A as the percent load factor determine the heat rejection from the previous page. 3. From Table B find the HT and LT circuit multiplier. 4. Multiply the result of step 2 by the result of step 3 to obtain the heat rejection at your altitude and temperature.
