Description

COOLSPEC SUPREME OAT LL50 - Long-Life Organics Acid Technology Coolant

COOLSPEC SUPREME OAT LL50 is a premium 50% premixed, ready-to-use long-life coolant formulated with advanced Organic Acid Technology (OAT) inhibitors for superior engine protection and extended drain intervals.

Free from silicates, phosphates, amines and borates, this high-performance coolant meets the demanding requirements of modern diesel, petrol and gas engines operating in both on-road and off-road environments.

Designed for applications where extended service life, reduced maintenance and exceptional corrosion control are essential, COOLSPEC SUPREME OAT LL50 guarantees consistent cooling efficiency while preventing scale, liner pitting and overheating under tough operating conditions.

Recommended Applications

  • Modern Diesel and Petrol Engines using OAT/LL coolants
  • Agricultural Machinery (tractors, loaders, telehandlers)
  • Construction and Quarry Equipment
  • Commercial Fleets & HGVs
  • Plant Hire and Industrial Engines
  • Stationary Engines, Generators and Compressors
  • Vehicle requiring Long_life OAT Coolant Meeting Major OEM Specifications
  • Suitable for: ASTM D3306, D4656, D4985, D6210 BS 6580:2010 Chrysler MS 9176 CNH MAT 3624, MAT 3724 Cummins CES 14603, 14439 DAF 74002 Daimler Truck DTFR 29D110 Deutz DQC CB-14 Ford ESD-M97B49-A, WSS-M97B44-D GM 1899M, 6277M, 3420, B 040 1065 IVECO 18-1830 Jaguar Land Rover STJLR.651.5003 Leyland Trucks LTS 22 AF 10 Mack 014GS 17004 MAN 324 SNF Mercedes-Benz 326.3 NATO S-759 Opel QL130100 Renault 41-01-001 Type D Rolls-Royce Bergen 2.13.01 Volvo VCS VW Group TL-774 D&F (G12, G12 Plus) UNE 26361-88 Suitable to use where G30, G33 & G34 is specified.

Key Benefits

  • Extended Long-Life Performance: Provides up to 5 years or 240,000 km protection (application dependent), reducing downtime and maintenance costs
  • Advanced OAT Inhibitor System: Organic corrosion inhibitors protect aluminium, cast iron, solder, brass and steel components without forming abrasive deposits.
  • Ready-to-Use 50% Premix: No need for dilution, ensures consistent freeze, boil and corrosion protection with soft, deionised water.
  • Superior Corrosion & Cavitation Protection: Prevents water pump wear, liner pitting and internal corrosion - critical for high-load diesel engines.
  • Silicate -, Borate - & Phosphate - Free: Reduces risk of drop-out, gel formation and abrasive deposits common in traditional coolant formulations.
  • Excellent Thermal Transfer Efficiency: Helps engines run cooler under heavy load, improving fuel efficiency and engine longevity.
