small capacity centrifugal compressor options

[AlexW_imported]

I have been reading up on centrifugal compressors, and I keep seeing references that small capacity versions exist in the 25 TR to 80 TR range, but I have not been able to determine manufacturers at this small of a capacity. Would anyone be able to point me towards some manufacturers? This range is ideal for my application.

I'm looking to use one with R134a or R513A.


Regards,

Alex

Nobody makes them as they are very inefficient at such low capacities

That's interesting. The lowest turndown I've seen advertised is 60 TR with Danfoss.

The ASHRAE journal has cited that the technology exists, so I was seeking additional information to see who might be making them that small.


Thanks,

Alex

Can you buy a 60 tons centrifugal chiller package from Danfoss?If yes compare it against similar capacity machines and see what you get
