Heavy Duty OAT Antifreeze

Heavy Duty Conventional

Crystal Clean HD OAT is the latest generation of coolant chemistry for heavy-duty applications requiring
ethylene glycol-based, extended-life coolant with OAT technology. It delivers superior performance and
durability under demanding engine conditions with higher temperature stability and excellent heat
transfer for CNG, EGR, and SCR systems.

Crystal Clean HD OAT is an all-organic formulation using inhibitor technology that contains no inorganic
salts (i.e. nitrite, nitrate, silicate, phosphate, borate), amines, or 2-ethylhexanoic acid. It minimizes
deposits, protects metals, is highly compatible with non-metal components, and provides outstanding
cylinder liner cavitation protection. It is also compatible with all major OAT coolants without precipitation
issues under typical top-offs.

Benefits:

• Meets the performance requirements of ASTM D6210, ASTM D3306, RP364, and RP338A
• Ready-to-use prediluted 50/50
• In HD applications, performance up-to 1,000,000 miles/20,000 hours in well maintained systems
• Protects all system metals.
• Available in red or yellow color
