Anyone know if a 7 1/2 ton two circut two compressor unit is available. I am only finding 10 tons or better.

Carrier has 15 ton package units (2 stage, Danfoss SRH752 / 7.5tons each compressors I believe) But all the ones we have here are water cooled, dont know what your lookin for. Im sure they have aircooled as well.

ICP CAE090GHC, is the 208 volt, 3 phase model. Dual copeland scrolls, GE fan motor. I've havent had any trouble with them. $2500 out the door at United Refrigeration. Its a single circuit though.

Where do u get the idea that they make them anyway? How would you split 7.5 tons of cooling into 2 even stages?

Thanks for the help in locating this unit, it is not to popular in my circles, so all the local manufactures wanted to sell what they stock.

I may have missed it but looks like York 2 circuit start at 10 ton. That Addison is a 2 circuit at 7.5. Probably pretty pricey! And speaking of pricey, AAON is 2 circuit at 7.5 ton too.

I was working on something similar once and decided to go with 2 separate condensing units, equipment is much cheaper.

I like AAON units do you know if they make a split or is it just RTU'S?

I was going to suggest two 4 ton units staged... equipment would be MUCH cheaper!

Lennox makes a LCA090H2B (R22) OR -H4B (R-410A) RTU with 2 scroll compressors, and optional humidity control package that uses a hot gas reheat coil in the evaporator section.

a lot of people seem to want him to use a package unit?

The 8ton Aaon would work

Yea...my bad. Up here where I live nobody really asks for anything but packaged when it comes to commercial units. I also assumed roof top :oops:
