More BioTherm Products

Ecologically and Environmentally Friendly Non Toxic Heat Transfer Fluid with Antifreeze. Based on Refined Vegetable Extracts and ASTM D1384 proven Corrosion, Scale and Biological Inhibitors, for use in Biomass Heating Systems.

BioTherm VB4 has been especially formulated to provide Biomass Heating System installers with a heat transfer fluid that is 100% RENEWABLE. I.E. not derived from non-renewable crude oil. BioTherm VB4 is based on sustainable Refined Vegetable Extracts that are Non Toxic, Bio-Degradable and more thermally efficient than Propylene Glycol based coolants. Subsequently BioTherm VB4 could be considered the most ecologically friendly antifreeze available.


Antifreeze AntiFreeze

BioTherm VB4 is miscible with water in all proportions and can protect Biomass Heating Systems down to -50°C depending on concentration.

non toxic Non Toxic

BioTherm VB4 has an LD50 toxicity rating (Oral Rat) of ≥15,000 mg/kg of body weight (bw) = “Relatively Harmless”. As confirmed by the Hodge & Sterner Scale.

Renewable Renewable

Manufactured using a blend of refined vegetable extracts. I.E. they do not contain any crude oil derived or synthetic constituents

Corrosion control Corrosion Control

BioTherm VB4 contains synergistic corrosion inhibitors to protect metals commonly found in such systems. It has been tested in accordance with BS5117 and found to meet BS6580 and ASTM D1384 corrosion standards.

BioTherm VB4 also contains scale and biological inhibitors to help prevent fouling – thus promoting long operational life and high thermal efficiency.

Biodegradable Biodegradable

BioTherm VB4 mixtures are readily biodegradable (90% over ten days) and will not remain in the environment or bio-accumulate.

Qulaity Assured Quality Assured

All Hydratech products are manufactured in accordance with certified ISO9001-2008 procedures

Application

As per BSRIA guide BG 29/2012 all pipe-work systems should be clean and free from biological contamination and debris prior to commissioning.

To minimise corrosion air ingress should be minimised. A pressurised system is best.

Determine the total system volume and add BioTherm VB4 to the system according to the minimum operating temperature required (see table, below). The minimum dose of BioTherm VB4 should not be less than 25% of the system volume and the maximum does not normally exceed 60%. We recommend the use of deionised, distilled or UltraPure™ water for this dilution. Avoid water containing high levels of calcium salts or Chlorides [Cl-].

Health & Safety: Please refer to the associated Safety Data Sheet - available via Login or upon request.

Shelf Life: 3 years when stored in sealed containers out of direct sunlight.

Available in: 5, 10, 15, 20, 25, 205 & 1000 litre containers and bulk tankers.

BioTherm VB4 can also be supplied as a Ready-To-Use solution.
