1) Refrigeration coils can often approach sub-zero temperatures when operating, which means that any coils exposed to air will likely form ice or condensation on them. Its extremely important that this frost, ice, and water NOT enter your system as the water will contaminate the coolant and destroy its dielectric strength. We have seen this occur when people place a cooling coil into the coolant and not insulate exposed cooling coils that are placed above their cooling tanks.
2) Because the refrigeration coils can get so cold, circulation of the cooling is critically important, or you will have a significant temperature stratification of coolant in the tank and across your equipment. Most common electrical components are designed to have a component skin operation temperature in range of 10-90C, this means that you do not want to freeze these components, or their performance will suffer. This is especially important when working with our Dielectric Coolants, which have a significantly higher thermal density than air and therefore are far better at removing heat from the skin of electronics, which is exactly why immersion cooling is so efficient!
3) Chillers are typically expensive equipment to build, own, and operate so keep in mind that this method will not be more efficient than simply using a liquid cooler like a liquid to air heat exchanger or dry cooler, or a liquid-to-liquid heat exchanger if you have access to a water source.
