Lube oil treatment
Lubricating oil quality directly affects engine life. Clean oil reduces wear, prevents damage, and ensures reliable marine engine performance. Continuous cleaning is essential. That’s why manufacturers recommend purifiers and automatic filters—they efficiently remove dirt, water, and combustion residues, helping protect the engine and extend its lifetime.
Advanced lube oil purification and filtration solutions
- Reduce friction leading to engine component wear
- Protect engine components against harmful deposits
- Maintain efficient heat transfer by keeping the lube oil viscosity low
- Avoid downtime and expensive repairs
- Maximum engine efficiency and service life
Alfa Laval lube oil treatment solutions protect your marine engine and sensitive equipment, helping them perform reliably over time. Separators, installed in bypass, remove water, combustion residues, and fine contaminants that degrade oil quality. Coolers maintain the right viscosity to support efficient heat transfer. Automatic filters capture remaining particles before they reach the engine—ensuring clean oil and strong protection.

Longer lasting and cleaner lube oil with Alfa Laval MIB 503 Separator
Aboard the Prins Maurits – a Dutch fishing vessel – Chief Engineer Auke van Slooten has doubled the life expectancy of his main engine’s lube oil, saving 1,400 L of oil a year and nearly two hours of cleaning time per week using an Alfa Laval MIB 503 Separator.
Alfa Laval lube oil treatment
Lubrication oil is an essential part of vessel operations and plays an important role in engine efficiency and overall engine lifetime. The cleaner you can keep the lubrication oil, the better it is for the engine. Effective cleaning also means the oil needs to be replaced less often, saving time and money in the long-term. Alfa Laval can offer the optimal solution to ensure your lubrication oil stays cleaner and lasts longer, while helping to ensure that your engine stays protected.

Heat recovery for lubrication oil treatment system
Energy efficiency strongly influences a vessel’s cost effectiveness and its environmental footprint. Improving energy efficiency lowers fuel consumption and related cost. In addition, it makes the operation more environmentally friendly. By installing an Alfa Laval Heatpac® CBM heat exchanger, it is possible to recover excess heat energy downstream of the separator, re-purposing it to heat the oil prior to separation and thereby reduce the load on both the separator preheater and the cooling system.
