The name of the unit is Melco "rooftop unit"
I am told these date back to the late 60s. THese four units are on a mall that was built between 1970-72. All four units are no longer used.

Melco unit
I have a customer in Houston who has one of these units.
Talk about a Work Horse. I have photos of it but am unable to upload them. This unit is a 25 H.P. 460 volt and holds 68 LBS of R-22. The biggest problem I have is the customer doesn't change filters often enough.

Nice. Is that a POS Carrier behind it?
Actually, I have to hold my tounge there.
Carrier has been one stinking pile since they made the ever dependable 50YQ-xxx, etc RTU's!
The new RTU's, even the commercial ones, are turds at times.

Yeah. the compressor is under that sheetmetal cover
and it has a belt-driven condenser fan. I worked on a rooftop that had four of these, two with bad heat exchangers (gas-fired units). They ended up getting junked
in favor of some new Lennox L-Series units.
Definitely a bit different design than an anything I had
previously seen.

Until about two years ago had five under contract, lost the contract on renewal. Units are a simple design, control systems have usually been hacked around. Heat is normally provided by a Reznor(if I remember correctly) unit built into the Melco.

Yep worked on many of them. Have not seen one this year but did 6 last year. A real work horse.
You think a new Carrier will hold up that long?
