Old Dunham-Bush nomenclature

[montanabama]

Got an old D-B unit with a junk TX. Anyone know how to read the nomenclature? What's the tonnage? I'm tempted to say 1600 btu on the condensing unit? Never seen a model number with an ampersand in it.

Condensing unit: AR-16H&C
Evap. unit: C145

None of our dealers can tell me anything about D-B.

surely its a decent sized unit, go with the compressor capacity at evap temp to size your valve. probably 1.25 to 1.5 ton

I've got D/B literature dating from the 1960's and find nothing even close to that model number. Is this a belt-drive or a semi-hermetic? I don't recall ever seeing one with a 16 in the model number.

For a short time in the 1960's they did make some 1/4 and 1/3 hp hermetic condensing units with Kelvinator or Tecumseh compressors, but I have no info left for those.
