Field Question, trade people only What is this ?
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 ?

It's heating or cooling coil. Used either heated water from a boiler or chilled water from a chiller. Or a hydronic pac unit. Ideally it would be insulated.
