Description
Industrial Grade Secondary Refrigerant Antifreeze based on Ethylene Glycol
BLENDED WITH BS6580 PROVEN CORROSION, SCALE AND BIOLOGICAL INHIBITORS
We recommend a dilution of 20% Coolflow to 80% ultrapure water, which protects against freezing down to -10°C. For concentrations greater than 30%, please consult Thermal Exchange.
Health & Safety Instructions: COOLFLOW EG is classed as harmful if swallowed and may cause irritation to skin and eyes. Always wear appropriate personal protective gear when handling chemicals, including goggles and rubber gloves. Please refer to the associated Safety Data Sheet

Summary – Rating: B
Suitable for industrial process cooling, where a toxic classification is not an issue. Good thermal and pumping characteristics.
Efficiency – Rating: B
High thermal conductivity and low viscosity at sub-zero temperatures, results in increased heat transfer efficiency and reduced energy demands.
Antifreeze – Rating: A
Provides protection down to -50°C and lower concentration (% volume) is required to achieve the same freeze-point protection.
Corrosion Control – Rating: A
Long-Life formulation with synergistic corrosion inhibitors to exceed BS6580 and ASTM D1384 standards. Also contains broad-spectrum biological inhibitors and polyacrylates to prevent scale precipitation.
Toxicity – Rating: D
Classified as Harmful but usually considered as Toxic. Suitable for industrial cooling systems where toxicity is not an issue.
