Coolant with Corrosion, Scale, and Biological Inhibitors
Coolflow DTX Coolant, 5 L
Thorlabs offers non-toxic Coolflow DTX Refrigerant Antifreeze with Corrosion, Scale, and Biological Inhibitors for use with chillers. Made with ethylene glycol, this pre-diluted coolant features more efficient heat transfer characteristics than alternatives based on propylene glycol, such as lower dynamic viscosity and higher thermal conductivity; see the Specifications table for more details. Though ethylene glycol is usually toxic, Coolflow DTX contains the additive DeTox®†, which makes the solution non-harmful to humans and animals if accidentally ingested. More information regarding material safety can be found in the MSDS sheet here.
To promote a long operational lifetime, Coolflow DTX includes inhibiters to suppress the chemical reactions that cause galvanic corrosion, which is an electrochemical process occurring when two dissimilar metals are electrically connected and immersed in an electrolyte. This coolant also features scale and biological inhibitors to prevent fouling and algae bloom to maintain high thermal efficiencies.
Coolflow DTX has a viscosity low enough to not greatly effect pump motor efficiencies, making it ideal for use with a wide variety of chillers and other equipment that needs to be cooled. Offered in five liter quantities, the Coolflow DTX solution is pre-diluted with UltraPure water to a concentration of 28.0%. The solution at this concentration has frost protection down to -15 °C; however, we recommend a minimum operating temperature of -10 °C to reduce the risk of the temperature dropping below the frost protection value. Coolflow DTX supports a maximum constant operating temperature of 85 °C, as well as instantaneous temperature fluctuations up to 95 °C. It has a shelf life of three years when stored in a sealed container below 40 °C out of direct sunlight.
