Potassium FormateBrine based antifreeze
Prior to the development of Potassium Formate and Potassium Acetate based brine's, Calcium Chloride brine was commonly used in large, low temperature cooling systems. Although cheap to manufacture, Calcium Chloride brine is highly corrosive to the metals used in modern chiller designs, especially to aluminium.
Potassium Formate brine has mostly superceded Potassium Acetate brine, as it is less corrosive and has very similar heat transfer characteristics.
Coolflow LVF uses the latest corrosion inhibitor technology to keep the natural corrosivity of Potassium Formate in check and is often used to replace earlier Hycool and Temper formulations.
