Well, it was news to this unheated, semi-enclosed industrial facility. After twenty years in it's current location, they decided to have an electrical contractor - one familiar with industrial work, and accustomed to RMC- instal some heaters.
Here are two pictures of a typical install. Does anyone notice anything unusual about the EMT run to the thermostat?

BTW, the installs were made when the weather was still nice, and have survived so far.
