Fluid Solutions Edition 2

Last year was the inaugural edition of our “Fluid Solutions” magazine dedicated to heat transfer fluids. The magazine was well received by our customers and we got a large amount of positive feedback. Many of our readers enjoyed going through some interesting facts about heat transfer fluids, refrigeration, corrosion and nano-technology. Some readers were fascinated by the tardigrade on our cover page. Even many of us were surprised to know the interesting facts about these tiny creatures; how they can survive under extreme conditions such as very low or high temperatures, the vacuum of space or the high pressure of the deepest part of the ocean, without food or water, and lethal radiation. These tardigrades teach us something: nature’s innovations sometimes far outweigh human accomplishments. Scientists and engineers should continue to learn from our surroundings to develop ground-breaking technologies and products.

This year you will find two review articles, three research papers, and a section called “Ask the Experts”, where we have covered several questions that are frequently asked by our customers. Similar to last year, we have incorporated a number of “Fun Facts” related to the topics covered. The articles in this edition cover a variety of topics ranging from contamination or degradation of heat transfer fluids to high temperature molten salt fluids. There is a review article discussing different types of corrosion measurement techniques commonly used for heat transfer fluids. A thorough research paper demonstrates the effect of sunlight, specifically UV light, on the degradation of glycols. This is important to many glycol users since they might be storing the product outside. Another research paper shows how moisture solubility in a hydrocarbon-based heat transfer fluid changes with temperature and how to desiccate a fluid at very low temperatures. Chloride ion measurement techniques are discussed in another research paper since these ions can negatively affect a heat transfer fluid system by initiating pitting corrosion.
