    19dk

    I have been studying our chillers just trying to learn as much as I can, that goes for all the equipment we have but after reading (more than once) my startup, operation, and maintenance instructions for our 19dk chillers I still can not figure exactly what the purpose of these lines are. any info plus whatever else you know about carrier 19dk chillers would be appreciated.19dk example.jpg19dk example 2.jpg

    It has been a while since I had one apart but if not mistaken the line with the square flange is the oil drain and the round flange is the ref. drain line.

    square flange is oil drain. the insulated round one is motor cooling suction line. There is a check valve in the flange.

    Hey the machine looks nice. Insul is tight and paint looks good. That is the "motor drain down" line. Drains refrigerant from the motor shell back to the low side pressure.

    Thank you, sir. These machine have been maintained well. Started in March of '88 and still running strong. When we have out next inspection I will definitely have the tech show me around this machine so I can take some good notes.

    Nice machine! Square flange actually connects the upper and lower oil sumps together.

    They even piped in the auxiliary oil filters. That has to be one of the nicer plants, I've seen to have machines that old.
