Sizes 30 and 40, version NR & Size 50, version NR
- Fuels : HFO, Natural gas, LPG.
- Stated oil throughputs are based on a calorific value of 11.24 kWh/kg for HFO.
- Plotted operational ranges represent maximal values measured on idealised flame tubes in accordance with EN 676 and EN 267.
- Stated ratings are based on an air temperature of 20 °C and an installation altitude of 500 m above sea level.
- For installations at higher altitudes, a reduction in capacity of 1 % per 100 m above sea level should be taken into account.
