Cooling water for summer competition vehicles that is mainly composed of pure water to keep running at full power. Uses pure water that has a specific heat approximately 5 times that of coolant. Although it absorbs a lot of heat, the water temperature rises slowly. The water temperature does not easily rise even running continously on the circuit. *Noote: the above are test results for our products. A high-performance coolant designed for use in motorsports. The main ingredient of PG55 TA is highly filtered pure water, with proprietary addictives added to aid performance. It does not contain any ethylene glycol or propylene glycol, which are the main components of common coolants. The amount of heat required to raise the temperature of a substance by 1 degree per gram is called specific heat. The higher the specific heat value, the more heat is required. A typical ethylene glycol aqueous solution (45%) coolant has a specific heat of 3.31. On the other hand, the specific heat of pure water is 4.025, and the pure water that is the base of PG55 TA has an overwhelmingly higher specific heat than various substances, and has the effect of suppressing the rise in water temperature and the heat absorption effect that takes away heat. PG55 TA is a pure water based cooling water suitable for cooling performance. In other words, even if the water temperature of regular coolant and pure water is the same, the amount of heat absorbed to reach that temperature is significantly different. As you can see from this, PG55 is a cooolant that efficiently absorbs a lot of the heat generated by high-power engines while also preventing the water temperature from rising too high. PG55 TA is a product exclusively for motorsports, so please be sure to read the precaustions and be careful when using it. Precautions for using PG55 TA. This product is for motor sports only. Please do not use it on cars for general driving. - This product has special handling methods so please purchase it at a motorsports ppro-shop. (Flushing water sold seperately may be required.) - This product may freeze at outside temperature below 0 degrees, so please do not use it in winter. Also, even if the period of use is short, replace the coolant with antifreeze-containing coolant before winter. - When the pure water, which is the main ingredient of this product, comes into contact with air, it willl mix with impurities in the air and begin to deteriorate, so please use it up after opening. - The application of this product is limited to automotive engine cooling water. Not for drinking. It cannot be used for cleaning food or tableware. Nevver use on people, animals, or plants. When installing the PG55 TA, i would like you to replace as much of the cooling water as pssible. - If it is difficult to replace the entire amount, please use our product "Flushing Water" and replace it 3 to 4 times - When the waste liiquid beceomes clear, add TA. The cooling effect of the TA is maximized. RECOMMENDED FOR: ONLY FOR COMPETITION CARS SUCH AS TIME ATTACK
