Re: Trace Heating for fine coal hopper

Its would be entirely possible for condensation of water to form with temperatures as low as 4 degree C. That will be well below the dew point in humid conditions.

Re: Trace Heating for fine coal hopper

Rather than heat tracing; we installed 4 inches of insulation material on our Fine Coal Bin. Low temperatures inside our fine coal bin building can approach -10 C. We went through detailed calculations to arrive at the insulation thickness. Let me know if you need further help.
