Coolblend TX
Thermal Xcellence (Coolblend TX) is Blended’s range of specially formulated non-hazardous, glycol-based heat transfer fluids. These formulations contain premium multi-metal corrosion and scale inhibitors* to prevent internal corrosion and scaling, limiting downtime. TX formulations have market leading thermal conductivity and viscosity when compared to other glycol products, and can be used to top-up existing non-hazardous glycol-based systems**. TX systems have significantly higher heat transfer properties, resulting in lower energy costs, reduced carbon footprint but importantly, non-hazardous.
