I tried CIP using the offset top 1.5 TC ports and the coils still in place but that didn't work well. I was using my Spike pump. Maybe with the coil out and the sprayer centered or possibly a stronger pump. I'm still figuring out what is easiest/fastest but I think a soak and then just manually cleaning might be simplest. They aren't heavy empty. I have an Icemaster 100 so an open base no shelf would be needed for me and just measuring it, it is about 28.5" tall with the wheels. I'm tall so I may still do it, it would free up the chiller footprint and keep me from having to get down on the garage floor to do dumps. My back and hips certainly would appreciate it, thanks for the idea!
I don't think the Spike pump or the Riptide are aggressive enough to clean center mounted coils but it's good for the jacketed types. A friend of mine can clean the Spike with the coils using a 1/2HP brewery pump. It's so aggressive the fermenters shake.
