Emissions requirements have been a challenge for the industry, but Case IH engines continue to come out ahead with SCR-only technology. Tier 4B final emissions require higher combustion temperatures and cylinder pressures. Because these new engines run hotter, that can create deposits faster than previous engines. Akcela Actifull OT (OAT) Extended-Life Coolant has been developed to resist deposit buildup, cylinder liner cavitation and other issues that can occur in extreme conditions.
Akcela Actifull OT (OAT) Extended-Life is the Factory fill and required service fill coolant for FPT Tier 4B engines in all Case equipment. Not only is OAT coolant beneficial in Case engines, but it provides MAXIMUM protection for all engines – legacy to Tier 4B. Maintaining OAT nitrate levels is very important and can be checked with conventional test strips. OAT can be used in place of conventional anti-freeze in other cooling systems once a proper flush procedure has been performed. Machines requiring this product can be easily identified by decals on the overflow tank and radiator shroud (see image below).
- Organic Additive Technology (OAT)
- Extended life coolant
- Ethylene glycol base
- Offers superior protection
- Avoids deposit build up
- Eliminates cavitation issues
- Long service life
- No DCA required
The yellow color of the coolant also differs from the conventional blue, giving technicians another way to determine the type of coolant a machine needs. This identification is important since OAT should never be mixed with conventional coolant. These coolants are not compatible and will cause adverse effects to both the engine and cooling system.
One major advantage of OAT coolant is an extended service life of 4 years/4,000 hours, as compared to 2 years/2,000 hours with conventional coolant. OAT coolant also uses organic salts for corrosion and cavitation protection. The organic salts produce a protective film on the cylinder liners, thus preventing cavitation erosion. Actifull OT is a standalone product that does not require supplemental DCA additives. It is available in both concentrate and 50/50 premix formulas.
