Thawing Frozen Pressure Valves

if the guage is freezing, may try one of the hand warmer packets on it. i haul cement, and usualy if the guage don't work there is a blockage in the line, pull the line loose from both ends and see if you can blow thru it.

 

You could try either a hair dryer or a hand held air heater that is used in the shop to remove inspection stickers and other stuck on things.

Or undo the line up stream from the gauge and pour a little alchol or line anti freeze in it and hook it back up and repressure the tank.

Have you been hauling wet or damp product for the gauge to freeze up? The warm air from the tank should thaw it out. If the line isn't warm then look to see if there is a relief nut on the gauge and loosen it so the air moves faster through the line so warm air gets to the gauge and warms it up a bit.

If this problem keeps happening then you might have the shop put a water trap on the line so any moisture will be removed from the line before it gets to the gauge. Or have them remove the gauge and do like you can do with a wet cell and drop it in a can of rice to soak any moisture out of it or put it in the office oven if you have one or just replace it!

 

Maybe a gallon or so of hot water. Trying keeping the parts covered in grease after you do get it thawed out. This will help a little bit. You can wrap them with a towel or something. Well, it works here in Florida, maybe too cold for that trick up there!

 

Have you blown off any damp product that you know of? The heat of the air comming of of your blower should pretty much dry out any moisture in the air. Also, if you or someone used an air compressor to offload instead of the truck mounted blower it may have pumped some water into the trailer. I used to haul bulk Barite, Cement, Lime, etc. so we were pretty picky about moisture.
