Find out if replacing conventional pressurized refrigerants with an organic salt as the heat transfer fluid in your secondary loop heat transfer design is a cost-effective and safe enabler for your process.
Some common problems you might find with glycol heat transfer fluids include frequent testing to ensure proper pH is maintained, formation of rust deposits, maintenance of water-to-concentrate ratio, and instability of the base fluid. This condition is accelerated by the use of tap water as that portion of the water/concentrate mix. Deionized water or water that meets specific quality requirements should be used. Figure 1 depicts a schematic of a typical cold loop system.
