In fluid thermodynamics, a heat transfer fluid is a gas or liquid that takes part in heat transfer by serving as an intermediary in cooling on one side of a process, transporting and storing thermal energy, and heating on another side of a process.
A non-toxic fully inhibited heat transfer fluid, with antifreeze function based on detoxified ethylene glycol. Suitable for use in all RAC, HVAC and glycol chiller systems, including; process cooling, blast freezing, refrigeration and air conditioning applications.
To prevent internal corrosion, scaling and biological fouling Coolflow DTX is formulated with multi-metal and multi-function inhibitors, which exceed ASTM D1384 standards.
Launched in 2010 Coolflow DTX represents a major step forward in heat transfer and pumping efficiency, providing >10% reduction in operating costs when compared with Propylene Glycol based fluids.
Summary – Rating: A
Suitable for food & beverage process cooling and other applications where a non-toxic classification is preferred. High efficiency and more cost effective than MPG based coolants.
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 -58°F and lower concentration (% volume) is required to achieve the same freeze-point protection, when compared with NTP, USP, ECO2 and ECO3.
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: A
Classified as Non-Toxic and Food-Safe. Suitable for food & beverage processing systems and where low-toxicity is stipulated. LD50 Oral Rat >20,000mg/kg body weight.
When measuring the percentage concentration of Coolflow DTX in solution we recommend the use of a recently calibrated refractometer.
