DIESEL SWITCH Technical benefits

Manual change over valve DIESEL SWITCH ! risk of incidents due to uncontrolled change over ✔ automatic and safe change over unit with safety functions! risk of damages in fuel system due to temperature shocks ✔ no risk of incidents ✔improved temperature separation of fuel systems ✔effective change over or blending procedure ✔simple and universal design - easy installation ✔new and improved algorhythm for fuel change ✔viscosity monitoring with alarm function

Saving potentials considering fuel oil blending

Example• Sulphur-limit of 1 % in ECA • Price of MDO EURO 750.-/mt, price of HFO EURO 480.-/mt• 3 % Sulphur in HFO, 0.3 % Sulphur in MDO• Price of blend oil EURO 680.-/mt (Ratio = 26:74 = HFO:MDO)

ROI will be between 3...12 months!

Homogenizer (optional)

Homgenizing of fuel oil and fuel oil blends • Continious HFO homogenizing on board • Pure mechanical and no chemical treatment• Improved combusiton process• Reduced exhaust emissions
