Stop in for a cup of coffee

As seldom as it gets really cold here I had one electric over air solenoid on the old asphalt plant the lowest one on the plant and the one that HAS to function for the mixed AC to escape to the truck. Since it was the lowest of all of them and even with moisture traps on the air line it would freeze. When I knew such temps were in the future, out came the 1000w halogen lamp/heater to keep that solenoid warm at night.
