ELF
HDD Cool RTP Coolant

Low silicate formulation which is nitrite, phosphate and amine free. 

ELF H D COOL is a superior general purpose coolant based on “Hybrid Additive Technology” (HAT), which is a selectively balanced mixture of Organic and Inorganic Additives. HAT Formulations are more robust than those built on Organic Additive Technology (OAT) making HATs the product of choice for general servicing in Heavy Duty Applications.
