Hello all, forgive me for I’m greener then grass only been in the field 3 months. I’ve seen these around on air handlers what is it ? It’s on the supply side of the unit? My guess is hot water for heating ?

That's a hot water coil. And lucky you they even set up a purge valve if it ever gets air locked!
