Hello fellow knowledge seekers,
We make custom hvac/refrig. system dedicated for particular close tolerance lab conditions. We match a ceiling mounted evaporator to the room load and to a Copeland condensing unit that has compressor, condensor, receiver pre-assembled.
The evaporator coil manuf...
Hello friends,
My question is this:
