1 sty 2012 · Through a comparative analysis, we examine alternative options for solar thermal heat transfer fluids including water−steam mixtures (direct steam), ionic liquids/melts, and suspensions of...
Many applications in the heat processing industry are well suited to the use of heat transfer fluids to help regulate fluid temperature and provide a controlled environment for chemical reactions. Therminol fluids can be used in both medium-density fiberboard (MDF) and desalination applications.
Thermal expansion is the amount a given fluid expands when heated, or contracts when cooled. It is very low for water–a liter of water at 20 °C expands to 1.04 liters at 95 °C (4%). And it is much higher for silicon oil–a liter of a typical silicone oil at 20 °C expands to 1.10 liters at 120 °C (10%).
Synthetic heat transfer fluids, such as a propylene glycol or an ethylene glycol based fluid, are commonly chosen because they offer better heat transfer efficiency and excellent thermal stability. As a result, these fluids often have a longer lifespan than mineral fluids.
Therminol heat transfer fluids, available in various formulations and operating ranges, all provide excellent benefits—economy, efficient operation, minimum maintenance, and precise temperature control. Contact Eastman for detailed performance information on specific Therminol heat transfer fluids.
Therminol ® heat transfer fluids meet the operating needs of virtually any single- or multiple-station heat-using system. In properly designed systems, our fluids provide excellent thermal stability in their expected temperature ranges and provide years of trouble-free service with minimal downtime.
3 lis 2019 · HTFs must meet a number of key criteria depending on the specifics of the application. These include high-temperature thermal stability, product purity and heat transfer efficiency. The thermal stabilities and properties of mineral and synthetic HTFs differ.
