Potassium Formate

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Potassium Formate brine has mostly superceded Potassium Acetate brine, as it is less corrosive and has very similar heat transfer characteristics.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.

Potassium Formate based products

Coolflow LVF

Very Low Viscosity, Non Toxic Antifreeze and Secondary Refrigerant for process cooling & AC systems. Based on Potassium Formate and ASTM D1384 proven Corrosion, Scale and Biological Inhibitors.

Summary - Rating: BExcellent heat transfer and pumping characteristics, low toxicity but can prove a challenge to eliminate corrosion in some systems.
Efficiency - Rating: AExcellent heat transfer and pumping characteristics places LVF at the top of the efficiency tree, for all water-based antifreeze solutions.
Antifreeze - Rating: ADepending on concentration can provide freeze protection down to -60°C.

Corrosion Control - Rating: CCorrosive when in contact with air and only recommend for certain metals and closed loop pressurised systems.
Toxicity - Rating: BLD50 (Oral Rat) of 7,000 to 20,000 mg/kg body weight depending on concentration in water. Not FDA approved as a food additive, but can be considered food-safe and widely used in food & beverage cooling systems.

Density:1.2 - 1.4 g/cm³
pH:8.0 - 9.5 depending on inhibitors
Boiling Point:>100°C
Characteristics:a clear, low viscosity liquid. It is salty to the taste and has a non-pungent but characteristic aroma.
Available in: 5, 10, 15, 20, 25, 205 & 1000 litre containers and bulk tankers.
