How long should it take to build air pressure in cold temps?

Got to keep her warm during these cold days. I'm going to fire mine up now & shut her down before I leave for tonight. I'll idle her at 1100 for about 2 hours. It is going to get that cold or colder in pa tonight.

 

It has an electric heater where it exhausts. It took that long for it to warm up.
A trick to keep it from happening again.
When you park and shut down for the day, pump the brakes to get the compressor to activate. Then maybe ten psi before it cuts out, shut the truck off. Then the purge valve will be closed for the night.

 

HEy thanks for the tip!

 

-41C here in Saskatchewan this morning.

 

Happens to me on my truck on mornings of 20 degrees. Not 30 minutes though. More like 5 minutes.
guess won’t be happening again after taking this guys advice

 

We got that on Monday. -38C. It was a balmy -28C today though

 

Guys,..if you know your going from a hot to a cold region, before it gets to cold outside, stop and drain your air tanks.
By removing the moisture out of the tanks early, it will help keep everything from freezing up.

 

very true my friend but the issue is before the tanks and not in the tanks. You can have water in the tanks and it can freeze not causing any problems becuase the water obviously lays at the bottom. The air lines running in and out of the tanks are on the top
