Betaine based heat transfer fluid as a solution for toxicity and corrosion problems in heating and cooling systems.

Author(s) : JOKINEN J.

Summary

A betaine-water solution was tested and developed for heat transfer use. Betaine is by nature non-toxic and non-harmful to the environment. Adequate freezing protection is achieved with betaine concentrations of 20-55% by weight. This solution was found to have other good qualities as well; it has good heat transfer capabilities, is not harmful to materials regularly used in equipment and is less corrosive than pure water. The paper gives the results of measurements with different betaine concentrations. Laboratory and field-tests showed that a betaine-water solution performs well as a heat transfer fluid in the HVAC industry. The concrete result was a patented new product for the industry for the temperature range of -45 to 110 °C.
