Paraffinic fuels (according to EN 15940)
Paraffinic fuels ("synthetic diesel") have a high cetane number and a low density compared to
diesel fuels. HVOs (Hydrotreated Vegetable Oils) are renewable. GTLs (Gas-To-Liquids) are fossil
paraffinic fuels. The use of paraffinic fuels results in lower emissions, but also slightly higher
fuel consumption and lower performance.
When using paraffinic diesel, a reduced filter change interval may be necessary due to the
cleaning effect.
Rubber and elastomers in the fuel system can be affected when changing from diesel fuel to
paraffinic fuel. Check daily whether fuel is leaking, and contact customer service for assistance
if necessary.
Information
EN 15940 fits into specification ASTM D975 1D-15 and ASTM D975 2D-15.
16) Exchange interval of fuel filters is reduced (1/2), lifespan of fuel line components may be reduced, fuel consumption
is not guaranteed anymore.
17) Biodiesels are not recommended for ESP (Emergency Standby Power) generator set applications because of the risk
of bacteria development.
18) Specific improved storage condition is mandatory.
19) Reinforced fuel primary filtration system, including water separator between main storage and daily tank, is manda‐
tory.
20) Polishing primary fuel filtration is mandatory.
