I am trying to figure out a cost effective way to make a tank for GPU mining. For me that would be using refurbished rigid plastic 1000 liter IBC tanks (Intermediate bulk container - Wikipedia). Are these tanks compatible with your fluids? Do you have any experience with a setup in a IBC tank?
The 1000L IBC Totes are made of HDPE and are fully compatible with our Dielectric Coolants when the Coolants are at temperatures below 35C. However, once you get to operating temperatures of about 60C we have found that HDPE loses its rigidity and that can cause the HDPE material to fail under the weight of the equipment and fluid.
Unfortunately, we cannot recommend the use of 1000L HDPE Totes as immersion tanks due to their low thermal set temperatures.
