Hubbard-Hall, Clariant Develop Solar Heat-Transfer Fluid

Hubbard-Hall Inc., based in Waterbury, Conn., has partnered with Germany-based Clariant Corp. to make Antifrogen SOL HT heat-transfer fluid available in the U.S. The product, previously available only in Europe, is being offered in ready-to-use concentrations, packaged in five-gallon pails and 55-gallon drums.

Antifrogen SOL HT was developed as an alternative to traditional heat-transfer fluids that experience thermal decomposition at temperatures above 170° C (338°F). Typical glycol-based heat-transfer fluids tend to evaporate at high temperatures, which may leave insoluble residues, leading to operating problems or failure of the system, according to the companies. Antifrogen SOL HT is designed to withstand short-term stagnation temperatures of greater than 260° C (500°F) without breaking down and forming salt-like scale.

Antifrogen SOL HT also offers excellent corrosion inhibition in combined-metal environments, the companies add. Antifrogen is a non-hazardous, higher-glycol-based product with a price comparable to that of other brand-name glycols.
