Can anyone help with information regarding the Carrier 19 DR.
Thanks for any information.

The Carrier 19DR low pressure centrifugal chiller is a very interesting unit. Before we can answer your question additional information is needed, for example are the compressors DK or DM units, is the package chiller R-11 or has it been converted to R-123? Which control package in involved, 3200 complete with an ESP panel? The more information that you could provide would assist us in our ability to enhence your knowledge.

The chiller is still a R-11 machine with 3200mp with ESP panel. Compressors I am not sure about yet will know more tomarrow. The only information that I can find is about the surge/stall bullentin and IOM.

Are you having a problem with the machine or are you trying to find general information?

As you can see they are dual compressor machines yet there is only one refirgerant circuit.

They are also very good low load performers, but the best feature about these machines is their ability to operate with a wide range of GPM through the cooler which makes them perfect for a variable primary loop.

The fact that they are still R-11 is nothing to get concerned with.
Just keep it tight & add a condensing purge if it doesn't already have one.

How about a model number along with compressor model numbers.

I wouldn't post the serial number on here as some people think its cute or cool to announce to the whole world where this machine is located when they look it up.
