Chiller GlycolHigh Performance Glycols for Chillers

Chiller Glycol is a trade-specific phrase, often used by those in the refrigeration and air conditioning sectors, and/or when searching online.

Hydratech formulate and manufacture a wide range of glycol based heat transfer fluids that can also be classified as chiller-glycol.

Within this site, via the various drop-down menus, searchers of chiller glycol, or glycol for chillers, will find just about every conceivable formulation variation - a few of which are listed below.

Alternatively, you may prefer to call and discuss your specific chiller glycol requirements with one of our engineers.

A ABAAA

High Efficiency Non Toxic Antifreeze and Secondary Refrigerant for process cooling & AC systems. Based on Ethylene Glycol blended with patented DeTox™ additive and ASTM D1384 proven Corrosion, Scale and Biological Inhibitors.

Show more...

  • 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.

B BCBAA

Non Toxic Antifreeze and Secondary Refrigerant for process cooling & AC systems. Based on Propylene Glycol and ASTM D1384 proven Corrosion, Scale and Biological Inhibitors.

Show more...

  • Summary - Rating: BSuitable for food & beverage processing and other applications where a non-toxic classification is preferred. Average efficiency and relatively high cost per litre.

  • Efficiency - Rating: CAverage thermal conductivity and higher viscosity at sub-zero temperatures, results in reduced heat transfer efficiency and increased energy demands. Good Specific Heat capacity helps improve overall performance.

  • Antifreeze - Rating: BProvides protection down to -50°C but greater concentration (% 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 - 1.15 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.
