    Copeland DTC scroll compressor - Emerson DTC



    Has anyone had any issues with the new style demand cooling module leaking on scroll compressors running LT on R407F, we have had a few either split where full nuts have been fitted or have had the seal cap leaking. The gas looks to be escaping via the preset adjuster spindle. This looks to be a new design DTC. Has anyone else had this issue? photo 3.jpg

    I don't work on them. I wonder if refrigerant is leaking past the shrader and condensing into liquid in the cap, then when the pipe warms up it can't get back past the shrader quick enough and sort of hydraulics it?
