Commercial Grade Heat Transfer Fluid with Antifreeze for use in Hot Water Heating Systems. Based on Ethylene Glycol and ASTM D1384 High Temperature Rated Corrosion, Scale and Biological Inhibitors. 

ThermaFlow CMF has been especially formulated for use as a Commercial Grade Heat Transfer Fluid for use in Hot Water Heating Systems.


Antifreeze AntiFreeze

ThermaFlow CMF is miscible with water in all proportions and can protect Hot Water Heating Systems down to -50°C depending on concentration.

ThermaFlow CMF exhibits super-cooling characteristics and mixtures containing in excess of 55% by volume do not freeze solid, alleviating any concern over possible expansion and burst damage.

Optimum Flow Optimum Flow

ThermaFlow CMF has improved heat transfer characteristics. Including lower Dynamic Viscosity and higher Thermal Conductivity. Performance curves available upon request.

Corrosion control Corrosion Control

ThermaFlow CMF 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.

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

Biodegradable Biodegradable

ThermaFlow CMF 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 prior to commissioning.

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

Determine the total system volume and add ThermaFlow CMF to the system according to the minimum operating temperature required (see table). The minimum dose of ThermaFlow CMF 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.

ThermaFlow CMF can also be supplied as a Ready-To-Use solution.
