PRI-RS HFO treatment is our flagship chemistry - providing vessel operators worldwide optimum reliability, increased on-time scheduling and increased profitability. Verified for effectiveness in Marpol Annex VI testing by Man Diesel, PRI-RS has clearly established the capability to give far more than it costs. The key is PRI's proprietary thermal stability technology - formulated to prevent the formation of unburnable carbon during the combustion process. In turn, engine components remain much cleaner, particulate and unburned hydrocarbon emissions are reduced, and engines run more efficiently for much longer periods. PRI-RS provides a full range of benefits at the standard 1:4000 dosing ratio (online dosing pump recommended), including:

• Enhanced ignition quality
• Prevention of engine deposits
• Sludge reduction from 30-to-60 percent
• Protection against fuel incompatibility
• Prevention of vanadate deposits and high temperature corrosion
• Inhibition of soot accumulation in economizers
• Visible smoke reductions on an average of 45 percent
• Optimizaton of fuel consumption rates
