CoolFlow

Applied Thermal Control stock CoolFlow, an industrial grade refrigerant antifreeze based on ethylene glycol.

CoolFlow is sold by ATC in three variations.

All CoolFlow products are classed as harmful if swallowed and may cause irritation to skin and eyes. It is important to wear appropriate personal protective equipment when handling chemicals, including goggles and rubber gloves.

Associated Safety Data Sheets are available for all products within the CoolFlow range.

CoolFlow EG Concentrate is blended with BS6580 proven corrosion, scale, and biological inhibitors. A dilution of 20% CoolFlow to 80% ultrapure water is recommended, providing protection against freezing down to -10ºC. CoolFlow EG Concentrate is dark blue in colour and available in 5L and 25L containers.

Coolflow EG is suitable for industrial process cooling where toxic classification is of no concern. It is classed as harmful, but usually considered to be toxic. Coolflow EG has high thermal conductivity and low viscosity at sub-zero temperatures, resulting in increased heat transfer efficiency and reduced thermal demands.

Antifreeze protection is provided down to -50ºC, with a lower concentration (% volume) of Coolflow EG required to achieve the same freeze-point protection when compared with other ethylene glycol heat transfer fluids.

Coolflow EG contains synergistic corrosion inhibitors, exceeding BS6580 and ASTM D1384 standards. It also contains broad-spectrum biological inhibitors and polyacrylates to prevent scale precipitation.

Performance Rating for CoolFlow EG:

• Summary - A
• Efficiency - B
• Antifreeze - A
• Corrosion Control - A
• Toxicity - D

Mixing Guide for CoolFlow EG

When measuring the percentage concentration of Coolflow EG within solution, it is recommended that a recently calibrated refractometer is used.

Frost Protection ºC	%v/v of CoolFlow EG in System	Refractive Index
-10	20%	1.349
-15	27%	1.355
-20	32%	1.359
-25	37%	1.363
-30	41%	1.366
-35	45%	1.369

CoolFlow EG Pre-Mix is available as a 20% pre-mixed solution with ultrapure water. It is able to achieve -10ºC freeze protection. Coolflow EG Pre-Mix carries the same properties as CoolFlow EG and is light blue in colour.

CoolFlow 1 contains corrosion inhibitors tested in accordance with BS5117 and found to meet BS6580 and ASTM D1384 corrosion standards. CoolFlow 1 also contains scale and biological inhibitors. It is pre-mixed to a 20% solution, using ultrapure water, and achieves -10ºC freeze protection, and is dark pink in colour.

CoolFlow 1 is classified as harmful, but is usually considered to be toxic, so is usually used in industrial cooling systems where toxicity is not an issue. It has high thermal conductivity and low viscosity at sub-zero temperatures, resulting in increased heat transfer efficiency and increased heat recovery.

Protection is provided down to -50ºC, with less volume required to achieve the same freeze-point protection when compared to other ethylene glycol-based heat transfer fluids

CoolFlow 1 is a long-life, temperature rated formulation, with synergistic corrosion inhibitors exceeding ASTM D1384 standards. CoolFlow 1 contains broad-spectrum biological inhibitors and polyacrylates to prevent scale precipitation.  

Coolflow 1 is available in 25L containers.

Performance Rating for CoolFlow 1

• Summary - B
• Efficiency - B
• Antifreeze - A
• Corrosion Control - A
• Toxicity - D

 

CoolFlow B concentrate is a corrosion inhibitor and biocide and should be dosed to the system at a ratio of 1:50. It is light pink in colour and is available in 1L and 5L containers.
