Coolflow Coolflow Secondary Refrigerants - CHW Systems

A range of fully inhibited coolants with antifreeze function for chilled water cooling systems. Coolflow products are installed in CHW systems of all sizes throughout the UK from the Eden Project to Barclays Bank.

To prevent internal corrosion, scaling and biological fouling all Coolflow products are formulated with multi-metal and multi-function inhibitors, which exceed ASTM D1384 standards.

  • Summary - Rating: ASuitable 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: BHigh thermal conductivity and low viscosity at sub-zero temperatures, results in increased heat transfer efficiency and reduced energy demands.

  • Antifreeze - Rating: AProvides protection down to -50°C and lower concentration (% volume) is required to achieve the same freeze-point protection, when compared with NTP, USP, ECO2 and ECO3.

  • Corrosion Control - Rating: ALong-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: AClassified 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.

  • Density:1.04 - 1.15 g/cm³ depending on inhibitors

  • pH:7.5 - 9.0 depending on inhibitors

  • Boiling Point:>100°C

  • Characteristics:a clear, slightly viscous liquid. It is mildly sweet 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.

Coolflow ECO2 Coolflow ECO2

B BCBAA

Ecologically and Environmentally Friendly Non Toxic Antifreeze and Secondary Refrigerant for process cooling & AC systems. Based on Refined Vegetable Extracts and ASTM D1384 proven Corrosion, Scale and Biological Inhibitors.

Show more...

  • Summary - Rating: BSuitable for systems where low environmental impact and ecological sustainability is preferred. Average efficiency but lower in cost compared with MPG based fluids.

  • Efficiency - Rating: CAverage thermal conductivity and high viscosity at sub-zero temperatures, results in reduced heat transfer efficiency and increased energy demands when compared with DTX, IGE and LVF.

  • Antifreeze - Rating: BProvides protection down to -50°C but more volume is required to achieve the same freeze-point protection compared with DTX, IGE and LVF.

  • Corrosion Control - Rating: ALong-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: AClassified 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.

  • Density:1.02 - 1.26 g/cm³

  • pH:7.5 - 9.0 depending on inhibitors

  • Boiling Point:>100°C

  • Characteristics:a clear, slightly viscous liquid. It is slightly sweet to the taste and has a non-pungent but characteristic aroma.
