Food grade: a closer inspection

摘要

Thermal fluid specialist, Global Heat Transfer has released a white paper analysing the benefits of using food grade thermal fluids in heat transfer systems. The special report includes the results of head-to-head testing of regular and food grade oils carried out by experts at the company. In the head-to-head experiment, Global Heat Transfer examined 1,223 fluid samples - 280 food grade, 943 non-food grade. The resultant data clearly showed mean and maximum values for carbon residue and TAN (Total Acid Number) were higher for non-food grade fluid than for food grade. The analysis demonstrated the non-fouling nature of a food grade thermal fluid, making it more sustainable and less costly to use in the long-run.
