Summary - Rating: ASuitable for biomass boiler heating systems and other heating applications where a non-toxic classification is preferred. High efficiency and more cost effective than MPG and bio-based coolants.
Efficiency - Rating: BHigh thermal conductivity and low viscosity at sub-zero temperatures, results in increased heat transfer efficiency and increased heat recovery.
Antifreeze - Rating: AProvides protection down to -50°C and less volume is required to achieve the same freeze-point protection, when compared with MPG based fluids.

Corrosion Control - Rating: A Long-Life high temperature rated formulation with synergistic corrosion inhibitors to exceed 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 systems where low-toxicity is stipulated or preferred.

Density:1.11 g/cm³
pH:7.5 - 9.0 depending on inhibitors
Boiling Point:>100°C
Characteristics:Clear, straw coloured, 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.

Biotherm BP8

Non Toxic Heat Transfer Fluid with Antifreeze Function. Based on Propylene Glycol and ASTM D1384 High Temperature Corrosion Inhibitors for Biomass Heating Systems.

Show less

Summary - Rating: BSuitable for biomass boiler heating systems where low toxicity is preferred. Average efficiency but higher cost compared with Biotherm VB4 fluid.
Efficiency - Rating: CAverage thermal conductivity and higher viscosity at sub-zero temperatures, results in reduced heat transfer efficiency and increased energy demands, compared with Biotherm DTX. 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 Biotherm DTX and BE2.

Corrosion Control - Rating: A Long-Life high temperature rated formulation with synergistic corrosion inhibitors to exceed 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 systems 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.
