Hi all, 

Does anyone know what can be done to avoid freezing issues or ore in silos in temperature as below as -40degrees celsius. 

We are using calcium chloride solution but it doesnt seem to be helping alot.

The only thing that seems to work reliably is using heat tracing, but this can be expensive depending on the silo size.

Also at -40 degrees you do not need to specify Celsius or Fahrenheit as they are the same.
