    Smardt Chiller Repair - Turbocor

    This was my first repair on a turbocor compressor. The IGV on compressor #1 stop responding.......couple months later compressor #2 IGV stop responding and got stuck in a fixed position just like #1 compressor. We talked to DTC they said there was a problem with some of the IGVs installed on some of the ealier compressors. Just finished up the repair today...... compressors came online and loaded up correctly.

    Looks good. What was the problem with the IGV? What year was the compressor built?

    I was wondering why this was in the HOS! Ping one of the moderators, they can move it for you.

    Did the ball bearing in the peep window indicate that it was stuck at 20% Or did it move the full 0-100 range? Did the IGV test ok?

    how do you test the IGV operation? is it thru the I/0 connector and danfoss sofware on your computer ?
    i have a turbocor compressor # 2 that IGV only go up to 12 % . the ball bearing not even move stay closed.
    after numerous time its tripped. no refrigeration effect at all.

    did not see any option on chiller control panel. this is Arctic cool chiller.

    You test the IGV operation with Turbocor 3G software and a connection through the interface board..
